After Ureteral Stone Removal: Stent Discomfort, Fluids and the Metabolic Work-Up That Follows

The stone is out. That was the sentence you wanted to hear in the recovery bay, and for about an hour it felt like the whole story. Then came the first walk to the bathroom: a sudden, almost electric urge, a sting at the end of the stream, a rosy tint in the bowl, and a dull pull under the ribs that showed up the moment your bladder emptied. Nobody warned you that the aftermath might be noisier than the stone itself.

That noise usually has a name. A ureteral stent after stone removal is the thin, curled tube your surgeon left behind, and it is doing exactly what it was designed to do. It is also, for many people, the least comfortable part of the whole episode.

This explainer walks through the three things that fill the weeks after ureteroscopy: living with and losing the stent, the plain business of fluids, and the metabolic work-up that turns one bad night into a plan for not repeating it. Every timeline here is a typical range from the cited sources, not a promise, and every decision stays with the team that treated you.

What a ureteral stent after stone removal actually is, and what happened in the operating room

The ureter is the narrow muscular tube, roughly the width of a drinking straw’s inner channel, that carries urine from each kidney to the bladder. A ureteral stent is a soft, hollow plastic tube placed inside that channel, with a curl at each end so it stays put: one loop rests in the kidney’s collecting system, the other sits in the bladder. Urine flows both through the tube and around it (Cleveland Clinic).

Most stones in the ureter today are removed by ureteroscopy. A ureteroscope, a slender instrument with a camera, is passed through the urethra and bladder and up the ureter with no incision. The surgeon either lifts the stone out in a tiny basket or breaks it into fragments with a laser fiber so the pieces can be removed or passed (Mayo Clinic; NHS). Some stones are treated instead with shock wave lithotripsy from outside the body, and a stent may follow that procedure too, particularly when the stone was large.

Why leave a tube behind after the stone is gone? Because the ureter has just had an instrument threaded through it, and often a laser fired inside it. The lining swells. In a passage that narrow, even mild swelling can slow urine to a trickle, and a kidney that cannot drain hurts in a way that closely mimics the original stone. The stent props the channel open while the swelling resolves, lets small residual fragments and clots pass, and gives any small tear a scaffold to heal along (Cleveland Clinic).

A useful mental image: the stent is a temporary drainage culvert under a road that has just been dug up. It is not treating anything itself. It is buying time for tissue to settle, and it comes out once that job is done.

Is a stent necessary after kidney stone removal? Who usually gets one and who can skip it

Not everyone needs a stent, and the decision is made in the operating room based on what the surgeon sees. When a small stone comes out cleanly, the ureter looks calm, and no access sheath was used, many surgeons will finish without a stent. Ureteroscopy without stenting is an accepted option for uncomplicated cases in mainstream urology practice, and it spares the patient the symptoms described below (Cleveland Clinic).

A stent is more likely to be placed when the ureter is judged to need protection or drainage. Common reasons include:

• visible swelling, bruising or a small tear in the ureteral lining after the stone was extracted
• a large stone burden, or many fragments still expected to pass
• a ureter that had to be gently stretched or that was tight around the scope
• signs of infection in the urine at the time of surgery, where drainage matters
• a solitary kidney, a transplanted kidney, or reduced kidney function, where any blockage carries more risk
• a planned second procedure in the coming weeks, where the stent keeps the passage easy to re-enter

Then there is the group who are asked to wait. If you arrive in the emergency department with an infected, blocked kidney, the safe sequence is usually drainage first and stone removal later. A stent (or a drain placed through the back) relieves the obstruction, antibiotics treat the infection, and the definitive stone procedure is scheduled once the fever has settled, often some weeks later (NHS). People on blood thinners, or those with an unstable medical condition, may also have their stone surgery staged in this way.

The honest answer to “is a stent necessary” is therefore: sometimes, and the surgeon who saw your ureter is the only person who can say why in your case. Ask. Knowing the reason makes the discomfort easier to tolerate.

What to expect with a stent after kidney stone removal: the symptoms and why they happen

Stent symptoms are so common that urologists have a shorthand for them, and they cluster around three sources of irritation (Cleveland Clinic).

The bladder end is the loud one. The lower curl sits on the bladder floor, a surface packed with nerve endings that normally only register stretch. A foreign loop resting there sends a constant “you need to go” signal. The result is urgency, frequency, waking at night, a sense of incomplete emptying, and a stinging or burning finish to the stream. Some people describe a small leak when they cough or laugh, because the irritated bladder contracts before they are ready.

The kidney end causes a different complaint: an ache in the flank or back, often worst at the moment of urination. When the bladder squeezes to empty, pressure travels up the open stent to the kidney, which briefly stretches. This is called reflux pain, and it explains why some people wince mid-stream and feel better once the flow stops.

The third source is the lining of the ureter and bladder itself, which has been touched by instruments and now rubs against plastic. That produces the pink, red or rust-colored urine most people notice, sometimes for the whole time the stent is in. Light bleeding that comes and goes, especially after activity, is expected. Heavy bleeding with clots that block the flow is not, and belongs in the red-flag section below.

Timing matters too. The first two or three days are usually the hardest, as the effects of anesthesia and any local anesthetic fade and the fresh irritation peaks. Many people find the symptoms ease, though rarely vanish, over the following week. Both a swelling ureter and a stent that has migrated slightly can make things worse, so a sudden change in pattern is worth a phone call rather than stoicism.

How long does a stent stay in after stone removal, and what decides that?

There is no single correct duration, and this is one of the most active areas of debate in stone surgery. In everyday practice, a stent placed after an uncomplicated ureteroscopy typically stays for a period measured in days to a few weeks; a stent placed for other reasons, such as a stricture or an obstruction that cannot yet be fixed, may remain for months and be exchanged on a schedule (Cleveland Clinic).

Several factors push the timeline one way or the other. A ureter that looked clean, with a small stone lifted out whole, may only need the stent for a short spell. A ureter with a laser-treated large stone, or with visible injury, usually earns a longer period of protection. If the stent was placed to drain infection ahead of surgery, it stays until the stone procedure is done. If a second-stage procedure is planned, the stent bridges the gap.

The other side of the ledger is why stents do not simply stay longer to be safe. The longer a stent remains, the more it irritates, the greater the chance of urinary infection, and the more likely it is to develop a crust of mineral deposits along its surface, a process called encrustation. A heavily encrusted stent can be difficult to remove. A stent that is forgotten, because a follow-up appointment was missed, is a well-recognized hazard in urology, which is why teams keep registers and why you will be asked to confirm your removal date (Cleveland Clinic).

The practical takeaway: before you leave, know two things. Is there a stent, and when and how is it coming out? Write the date somewhere you will see it. If life intervenes and the appointment slips, call the clinic rather than assuming a few extra weeks are harmless. In stent care, longer is not safer.

Living with a ureteral stent after stone removal: work, exercise, sex and travel

A stent does not require bed rest, and most people return to desk-based work within a few days once the anesthesia has worn off and they feel steady (Mayo Clinic). What it does require is honesty about how you feel, because activity and symptoms are linked.

Movement tends to increase the pink tint in the urine and can stir up flank ache, as the stent shifts slightly with each stride. That is not damage; it is friction. Walking is encouraged. Gentle cycling, swimming and light gym work are usually fine once you feel up to them, though many people choose to postpone running, contact sports and heavy lifting until the stent is out, simply because the jolting is unpleasant. Your surgeon may give specific limits if the ureter was injured, so those instructions override any general rule.

Sex is medically permitted with a stent unless you have been told otherwise. Some people find it uncomfortable because the bladder end is irritated, and men may notice discomfort or a trace of blood with ejaculation. Neither is harmful, but a little planning and communication with a partner goes a long way. If a string is attached to your stent, take care that it is not pulled.

Driving is a matter of comfort and any sedating pain medicine, not the stent itself. Travel is possible, but plan for frequent bathroom access, carry your procedure summary, and know where you would seek care if fever developed. Long flights while stented are not forbidden; they are simply tiring, and the stent should never be left in past its removal date because of a trip.

Alcohol and caffeine can sharpen bladder urgency in some people. If your evenings are miserable, an experiment with cutting back is low-risk and worth trying. Sleep often improves if you empty your bladder fully before bed and keep a night light on the route.

How the stent comes out: string removal or a quick cystoscopy

Stents leave in one of two ways, and knowing which applies to you removes a lot of worry.

If your surgeon attached a tether, sometimes called a string, a thin thread runs from the bladder end of the stent out through the urethra and is taped to the skin. Removal is then simple: at the agreed time, either a nurse or you yourself pulls the string steadily, and the stent slides out in a second or two. Patients are often startled by how quick it is. The sensation is a brief, odd tug and a moment of stinging, followed by relief. The advantage is no second procedure. The disadvantage is that the string can be pulled accidentally, and a stent that comes out early, before the ureter has settled, may need to be replaced. Follow the specific instructions you were given about when and how to pull.

If there is no string, the stent is removed with a flexible cystoscope, a thin camera passed through the urethra into the bladder, usually in a clinic room with a numbing gel rather than a general anesthetic. The surgeon sees the curl, grasps it with a tiny instrument, and withdraws it. The whole visit is typically short, and people go home the same day (Cleveland Clinic).

Occasionally the stent is exchanged rather than removed, if a second stone procedure is planned or if the ureter still needs support. This is decided by your team based on imaging or what was seen at surgery, not by the calendar alone.

One genuinely useful tip: drink a reasonable amount before the removal appointment so that you can urinate afterward, which flushes the urethra and confirms that everything is flowing. Then expect the first day after removal to feel like a smaller repeat of the first day after surgery.

What not to do after ureteral stent removal

The stent is out, and the temptation is to declare the episode over. A few habits in the following days make that more likely to be true.

Do not stop drinking. The ureter is still slightly swollen where the stent lay, and the bladder is irritated. Steady fluids keep urine dilute, which stings less, and keep any last fragments or clots moving. A sudden return to a coffee-only morning is the most common reason the first post-removal days feel worse than they need to (NHS).

Do not ignore fever. After removal there is a short window in which a small blockage from swelling, or a flare of infection, can show itself. Feeling hot, shivery, or generally unwell is not a normal part of healing and should be reported the same day, as the red-flag section explains.

Do not assume all flank pain is fine. Mild ache for a day or two is expected. Severe, colicky pain that builds in waves and makes you restless is the signature of a blocked kidney, and it means a fragment or swelling is obstructing the ureter now that the stent is no longer holding it open.

Do not throw the follow-up away. Removal is not the end of care. Your team will want to confirm the kidney is draining, sometimes with an ultrasound, and to start the metabolic work-up described below. People who skip this step lose the single best opportunity to lower their chance of a repeat stone (Harvard Health).

Do not stop or start any medicine on your own account. If you were given antibiotics or bladder-calming medicine while stented, the instructions about when to stop came from your prescriber, and any change should go back to them.

What you can do freely: walk, shower, return to normal food, and resume most activities as comfort allows.

Ureter healing after stent removal: how long does it really take?

People often expect instant normality once the stent is out, and are disappointed when the burning and urgency linger. Two different tissues are healing on two different clocks.

The bladder recovers fastest. Its lining, the urothelium, renews quickly, and once the foreign curl is gone the constant urge signal fades. Most people notice that frequency and stinging settle within a few days of removal, with the first day typically the worst (Cleveland Clinic). A trace of pink in the urine for a day or two is common as the spot where the stent rested weeps slightly.

The ureter is slower and quieter. Its lining also renews within days, but the muscle wall beneath it, which was stretched, instrumented and possibly lasered, takes longer to shed its swelling and regain its normal rhythmic squeeze. You do not feel this process directly. What you may feel is a mild, intermittent ache in the flank that fades over the following couple of weeks as the tissue settles. Guidance from the sources cited here describes recovery after ureteroscopy in terms of days to a few weeks rather than months (Mayo Clinic; NHS).

Scarring is the outcome everyone wants to avoid. A ureter that heals with a narrowed segment, called a stricture, can obstruct the kidney silently. This is uncommon after routine ureteroscopy, and it is precisely why some surgeons arrange a follow-up ultrasound or scan weeks after the stent is removed: to confirm that the kidney is draining freely rather than relying on the absence of pain, since a slowly obstructing kidney may hurt very little.

Healing, in short, is mostly invisible and mostly complete within weeks. Persistent or worsening flank pain after that point is not “still healing” and deserves a scan.

Fluids after stone surgery: how much, which ones, and why it matters more than any diet rule

If the metabolic work-up is the strategy, fluid is the tactic that almost everyone is given, because it works on every stone type by the same mechanism. Stones form when urine is so concentrated that minerals crystallize. Dilute the urine and crystals struggle to form, whatever your chemistry (NIH NIDDK).

How much is enough? Rather than a fixed volume, most guidance aims at a result: urine that is pale yellow or nearly clear throughout the day. To get there, the NHS suggests drinking up to about 3 liters of fluid spread across the day, and the Mayo Clinic describes roughly 2 to 3 quarts a day as a common target, with more in hot weather or during heavy exercise (NHS; Mayo Clinic). Anyone with heart failure, advanced kidney disease or a fluid restriction should have this target set individually by their clinician, not taken from a magazine.

Water is the backbone. Beyond that, the evidence is more nuanced than folklore suggests. Citrus juices such as lemon and orange contribute citrate, a natural inhibitor of calcium crystals, and are reasonable additions. Sugar-sweetened sodas and drinks high in fructose are associated with higher stone risk and are best limited (Harvard Health). Coffee and tea in ordinary amounts are not stone-formers and count toward fluid; the old advice to avoid them has not held up (Harvard Health). Alcohol contributes fluid but also dehydrates and can worsen bladder symptoms while stented.

Two practical habits matter more than the exact number. Spread intake across the day, including a glass before bed, because urine concentrates overnight. And carry a bottle: people who keep water in sight drink it, and people who wait for thirst usually do not reach their target. A pale-urine check each time you use the bathroom is the only monitoring most people need.

The metabolic work-up: what is tested after a kidney stone, and who needs the full version

A stone is a symptom, not a diagnosis. Something in your urine chemistry, your diet, your fluid habits, your medications or your genes allowed minerals to crystallize, and the metabolic work-up is the search for that something (NIH NIDDK).

Nearly everyone is offered a basic evaluation: a medical and dietary history, a review of medicines and supplements, blood tests for kidney function, calcium, uric acid and sometimes phosphate, and a urinalysis. The stone itself, or its fragments, are sent for composition analysis whenever they can be retrieved. That single result shapes everything that follows.

The fuller evaluation centers on a 24-hour urine collection. You collect every drop for a full day, on your usual diet and fluid intake, and the laboratory measures total volume, calcium, oxalate, citrate, uric acid, sodium, and acidity (pH), among others. The pattern points to a cause: low volume, too much calcium or oxalate, too little protective citrate, acidic urine that favors uric acid stones, or high sodium driving calcium loss. Many teams request two collections, because a single day can be unrepresentative, and they schedule them several weeks after surgery once you are back to normal eating and the stent is out (NIH NIDDK).

Who is usually offered the full work-up rather than the basic one? Mainstream guidance points to people with recurrent stones, children, anyone with stones in both kidneys or a solitary kidney, a strong family history, stones of uncommon composition such as cystine or uric acid, bowel disease or previous weight-loss surgery, and those with reduced kidney function. A first, uncomplicated calcium stone in an otherwise healthy adult may reasonably be managed with the basic tests, fluids and dietary review, though many people in that position ask for the fuller evaluation, and that is a fair conversation to have.

If blood calcium is high, your team may check parathyroid hormone, since an overactive parathyroid gland is a treatable cause of repeated calcium stones.

What your stone analysis tells you, and the diet changes the evidence actually supports

Once the laboratory reports what your stone was made of, the advice becomes specific. The table summarizes the main types and the dietary emphasis that mainstream sources attach to each (NIH NIDDK; Harvard Health).

Stone type	How common	What tends to drive it	Dietary emphasis usually discussed
Calcium oxalate	The most common type	Concentrated urine, high sodium, high oxalate, low dietary calcium, low citrate	Fluids; less salt; normal food calcium with meals; moderate high-oxalate foods; moderate animal protein
Calcium phosphate	Less common	Alkaline urine, high urinary calcium, some medical conditions	Fluids; less salt; clinician-guided, since alkali supplements can worsen it
Uric acid	A minority of stones	Acidic urine, high purine intake, gout, metabolic conditions	Fluids; less red meat, organ meat and shellfish; weight and glucose management
Struvite	Uncommon	Recurrent urinary infection with certain bacteria	Infection control matters more than diet
Cystine	Rare, inherited	A genetic defect in amino acid handling	Very high fluid intake; specialist-led plan

Three points deserve emphasis because they run against instinct. First, cutting calcium from the diet usually backfires for calcium oxalate formers: dietary calcium binds oxalate in the gut, so less calcium means more oxalate reaching the urine. Guidance favors normal food calcium, eaten with meals, rather than restriction (NIH NIDDK). Second, salt matters as much as calcium, because sodium pulls calcium into the urine. Third, the oxalate list is about proportion, not prohibition; spinach, rhubarb, nuts, wheat bran and some beans are high, but a varied diet with adequate calcium tolerates them in moderation (NIH NIDDK).

Any change you make should be checked against your 24-hour urine results, which is the only way to know whether it worked for you.

Medications that lower stone risk: what the main classes do, and who decides

For many people, fluids and diet adjustments are the whole plan. For others, particularly those whose urine chemistry stays abnormal despite those changes or who keep forming stones, a clinician may discuss medicine. The point of this section is to explain what the main classes do, not to suggest any of them; whether you need one, which one, and for how long is a decision for the prescriber who has your urine results in front of them.

Thiazide-type diuretics are the classic option for people whose urine carries too much calcium. Their relevant action here is not the water loss most people associate with diuretics but a shift in how the kidney handles calcium, so that less of it is excreted into the urine. Their effect is judged over months with repeat 24-hour urine collections, and they can lower potassium, so blood monitoring is part of the package (Mayo Clinic).

Alkali therapy, most often a citrate salt, works in two ways: citrate itself binds calcium in the urine and blocks crystal growth, and the alkali raises urine pH, which keeps uric acid dissolved. It is a mainstay for uric acid stones and for calcium stones with low urinary citrate. Because raising pH too far can favor calcium phosphate crystals, dosing is guided by urine testing, which is another reason this is not a self-directed treatment (Mayo Clinic).

Xanthine oxidase inhibitors reduce the body’s production of uric acid and are used when uric acid excretion is high, particularly in people who also have gout.

For struvite stones the treatment is fundamentally about eradicating infection and removing all stone material. For cystine stones, specialist medicines that make cystine more soluble exist and are managed in dedicated clinics.

Whatever is chosen, it is meant to be measured. If you start a stone-prevention medicine and nobody rechecks your urine, ask why. And never adjust or stop it because a website suggested you might.

What people often get wrong about stents, fluids and stone prevention

“Blood in the urine means something has gone wrong.” With a stent in, intermittent pink or red urine is expected and usually rises with activity. The concern is heavy bleeding with clots that block flow, or bleeding that comes with fever or severe pain, not color alone (Cleveland Clinic).

“If I drink less, I’ll need the bathroom less.” Concentrated urine irritates a stented bladder more, not less, and it is exactly the condition that formed the stone. Spreading fluid through the day, rather than cutting it, is what most people find eases the sting (NHS).

“The stent can fall out or move into my kidney.” The curls at both ends are designed to hold it in place. Slight migration can happen and may change symptoms, but stents do not wander into the kidney or vanish. A string-attached stent can be pulled out early, which is why you protect the string.

“Leaving the stent in longer is the cautious choice.” Longer indwelling raises infection risk and encrustation. The cautious choice is to remove it on the date your team set (Cleveland Clinic).

“Kidney stones come from too much calcium, so I’ll stop dairy.” Restricting dietary calcium usually increases urinary oxalate and can raise risk for calcium oxalate formers. Normal food calcium with meals is the mainstream recommendation (NIH NIDDK).

“I’ve had one stone, so I’ll probably never have another.” The odds run the other way: about half of people who form a stone form another within roughly five to seven years without prevention (Harvard Health). That statistic is the whole argument for the metabolic work-up.

“Cranberry juice prevents stones.” Its evidence relates to urinary infection, not stones, and some analyses suggest it may raise oxalate. It is not a stone-prevention strategy in mainstream guidance.

“Once the stent is out, I’m done.” Removal is the midpoint. Confirmation that the kidney drains, plus the stone analysis and urine chemistry, are the parts that change your future.

Questions to ask your care team before you leave and at follow-up

Recovery goes better when you leave the hospital knowing the shape of the next few weeks. These are the questions that, in practice, prevent the most confusion. Bring them written down; anesthesia is unkind to memory.

Before discharge:

• Do I have a stent? Is there a string attached, and if so, what exactly should I do with it?
• What is the planned removal date, and how will it be removed? Who do I call if that appointment is missed?
• Were all the stone fragments removed, or should I expect to pass some? Do you want me to strain my urine and save fragments for analysis?
• Was the stone sent to the laboratory for composition? When and how will I get the result?
• What symptoms are expected with this stent, and which ones should make me call the same day?
• Are there any activity limits specific to what you saw in my ureter?
• How much should I be drinking, given my other medical conditions?

At follow-up, once the stent is out:

• Do I need imaging to confirm the kidney is draining, and when?
• Do I need a 24-hour urine collection? One or two? When should I do it, and on what diet?
• Which blood tests are you checking, and is a parathyroid hormone level warranted?
• Based on my stone type, what are the two or three changes that would matter most for me specifically?
• If medicine is ever recommended, how would we measure whether it is working?
• How often should I be seen or imaged in the future, and is there a plan if I have pain again?

A good answer to any of these will include the reason behind it. If you hear a rule without a reason, it is fair to ask for one; the rationale is usually simple, and understanding it makes the rule easier to follow.

When to call your doctor: red-flag signs after ureteroscopy and stent removal

Most of what you feel with a stent is uncomfortable but safe. A short list of symptoms is different, and each one deserves a same-day call to your surgical team or, if you cannot reach them, urgent care or an emergency department (Cleveland Clinic; NHS; Mayo Clinic).

• Fever, chills or shaking, with or without urinary symptoms. An infection behind a partially blocked or instrumented kidney can worsen quickly and is treated as an emergency.
• Severe or escalating flank pain that comes in waves, makes you unable to sit still, or is not controlled by the pain plan you were given. This suggests obstruction from a fragment, clot or swelling.
• Heavy bleeding: urine that looks like pure blood, passing clots, or clots that stop you from urinating. Pink or rust-colored urine that comes and goes does not qualify.
• Inability to pass urine, or passing only a few drops with a full, painful bladder.
• Persistent vomiting that prevents you from keeping fluids down.
• A stent that appears to have come out, wholly or partly, before the planned date, or a string that has been pulled and now feels different.
• New confusion, dizziness or feeling faint, particularly alongside fever, which can indicate a spreading infection.

After the stent is removed, the same list applies for the following days, with extra attention to fever and severe flank pain, since those are the signs that the ureter has narrowed or a fragment has lodged now that the tube is gone.

Two quieter situations also warrant a call rather than waiting: symptoms that were improving and then clearly worsen, and any flank ache that persists beyond the few weeks of expected healing. Neither is an emergency, but both are reasons for your team to look, often with a simple ultrasound. When in doubt, the clinic would rather hear from you than not.

Frequently asked questions

Is a stent necessary after kidney stone removal?

Not always. After a small, cleanly removed stone with a calm-looking ureter, many surgeons finish without a stent. A stent is more likely when the ureter is swollen or injured, the stone burden was large, infection was present, the kidney is solitary, or a second procedure is planned. The decision is made in the operating room based on what the surgeon sees.

What should I expect with a stent after kidney stone removal?

Expect urgency, frequency, stinging at the end of urination, a flank ache that peaks mid-stream, and pink or rust-colored urine that rises with activity. The first two or three days are usually the hardest, with gradual easing over the following week. Fever, severe pain, heavy bleeding with clots, or inability to pass urine are not expected and need a same-day call.

What not to do after ureteral stent removal?

Do not cut back on fluids, ignore fever or severe flank pain, skip your follow-up, or change any prescribed medicine without your prescriber. The ureter is still slightly swollen after removal, so steady drinking and attention to warning signs matter for a few days. Walking, showering, normal eating and most everyday activities can resume as comfort allows.

How long does it take for the ureter to heal after stent removal?

Bladder symptoms usually settle within a few days of removal, while the ureter’s swelling and muscle tone recover over the following couple of weeks, mostly without any sensation. Sources describe recovery after ureteroscopy in days to a few weeks. Flank pain that persists or worsens beyond that point is not normal healing and should be assessed, often with an ultrasound.

Why does my kidney hurt when I urinate with a stent in?

Because the stent is an open tube, the pressure generated when your bladder contracts travels up to the kidney and briefly stretches it. This reflux pain typically eases as soon as the stream stops. Emptying the bladder without straining and keeping urine dilute can reduce it. Pain that is severe, constant, or accompanied by fever is a different matter and needs a call.

How much should I drink after kidney stone surgery?

The usual goal is urine that stays pale yellow through the day. The NHS suggests up to about 3 liters of fluid spread across the day, and the Mayo Clinic describes roughly 2 to 3 quarts as a common target, with more in heat or during exercise. People with heart failure, kidney disease or a fluid restriction should have an individual target set by their clinician.

What is a 24-hour urine test for kidney stones and when is it done?

It is a collection of all urine over a full day, analyzed for volume, calcium, oxalate, citrate, uric acid, sodium and acidity to find why stones formed. It is done on your usual diet and fluids, typically several weeks after surgery once the stent is out, and many teams request two collections because one day can be misleading.

Can I exercise or have sex with a ureteral stent?

Yes, unless your surgeon has given specific limits. Activity often increases pink urine and flank ache because the stent moves slightly, so many people postpone running and heavy lifting until removal for comfort rather than safety. Sex is permitted; some notice discomfort or a trace of blood, which is harmless. If a string is attached, take care it is not pulled.

Should I stop eating calcium or dairy to prevent another stone?

Usually not. For calcium oxalate stones, the most common type, dietary calcium binds oxalate in the gut so less reaches the urine; restricting it tends to raise risk. Mainstream guidance favors normal food calcium eaten with meals, less salt, adequate fluids and moderation of high-oxalate foods. Your stone analysis and urine results should guide any specific change.

What happens if a ureteral stent is left in too long?

The stent can become coated in mineral deposits, a process called encrustation, which makes removal harder and may require an extra procedure. Longer indwelling also increases the risk of urinary infection and prolongs symptoms. Forgotten stents are a recognized hazard, which is why teams track removal dates. If your appointment is missed, call the clinic promptly rather than waiting.
