How Is a Ureteral Stricture Repair Chosen? Endoscopic Widening vs Reconstructive Surgery

The scan report is one line long, but it changes the whole appointment: “moderate hydronephrosis, likely mid-ureteral stricture.” You came in for a nagging flank ache and a urine infection that would not settle. Now a urologist is drawing a tube on a notepad, pinching it narrow in the middle, and saying the words “we have two broad ways to fix this.”

That fork in the road, ureteral stricture endoscopic vs reconstruction, is one of the more genuinely balanced decisions in urology. One path threads a tiny instrument up through the bladder and stretches or cuts the scar from inside. The other removes the scarred segment and rebuilds the drainage with healthy tissue. Neither is automatically better. Each suits a different kind of scar, a different kidney, and a different person.

What follows is the reasoning behind that choice, laid out the way a good surgeon would explain it if the clinic ran twenty minutes over.

What is a ureteral stricture, and why does the repair choice matter?

The ureter is the narrow muscular tube, roughly the width of a drinking straw, that carries urine from each kidney down to the bladder. A ureteral stricture is a segment of that tube that has scarred and narrowed, so urine backs up behind it. The backed-up kidney swells, a state called hydronephrosis, and if the pressure persists, the filtering tissue slowly thins and loses function (Mayo Clinic; NHS).

Scars form for a handful of reasons. A stone lodged for weeks can injure the lining. Instruments passed during earlier procedures can leave a tight ring. Pelvic surgery, radiation therapy for gynecologic or bowel cancers, tuberculosis, and a rare inflammatory condition called retroperitoneal fibrosis, in which scar tissue behind the abdominal cavity wraps around the ureters, all appear on the list (Mayo Clinic). Sometimes no cause is ever found.

Why does the method of repair matter so much? Because scar tissue is stubborn. A stricture that is simply stretched can quietly contract again over months, and a kidney can lose function without much warning, since the other kidney often compensates and blood tests stay normal for a long time. The wrong tool for a particular scar means either repeated procedures or a bigger operation than was ever needed.

So the question is never “which treatment is best” in the abstract. It is “which treatment matches this scar, in this location, above this kidney, in this person.” The next sections walk through each of those variables in turn, because they are exactly what the surgical team will weigh before proposing a plan.

Is a ureteral stricture serious?

It can be, and the seriousness is measured less by pain than by pressure. A blocked kidney under sustained back-pressure is the real concern, and obstruction is a recognized route to kidney damage, infection, and in the worst case permanent loss of that kidney’s function (MedlinePlus; Mayo Clinic).

Two complications push the situation from “needs a plan” to “needs action now.” The first is infection above the blockage. Stagnant urine behind a stricture is an inviting environment for bacteria, and an infected, obstructed kidney can tip into sepsis, a body-wide response to infection that is a medical emergency (NHS). The second is silent functional loss, which is why teams measure how much each kidney contributes, often with a nuclear medicine renogram, a scan that tracks a small amount of tracer through each kidney to estimate its share of total function.

The reassuring side is that most strictures are found before either of those points, often incidentally on a scan done for something else, and there are effective ways to relieve the pressure quickly while the definitive repair is planned. A ureteral stent, a soft hollow tube placed inside the ureter to hold it open, or a nephrostomy tube, a drain placed through the back directly into the kidney, both decompress the system within minutes of placement (Cleveland Clinic; Mayo Clinic).

A useful mental picture: think of the stricture as a kink in a garden hose with the tap left on. The kink itself may never hurt. The swelling upstream is what damages the hose, and the longer it sits, the harder it is to reverse. That is why even a stricture that is producing no symptoms is generally not simply left alone once it is causing hydronephrosis.

How the team decides: five things that drive the ureteral stricture endoscopic vs reconstruction choice

Ask any reconstructive urologist how they choose and you will hear the same handful of variables, usually in roughly this order.

Length of the scar. This is the single largest factor. Short strictures, meaning a thin ring rather than a long tunnel of scar, are the ones most likely to stay open after being stretched or cut from inside. Long segments tend to recoil no matter how well they are dilated, because there is simply too much diseased tissue to remodel.

Location along the ureter. The ureter is described in thirds: upper (near the kidney), middle, and lower (near the bladder). Location determines which reconstruction is even possible. A lower stricture can often be repaired by reattaching the ureter directly to the bladder, whereas an upper one may need a different approach, discussed later.

Cause and tissue quality. Scar from a brief stone episode behaves very differently from scar in a field that received radiation years ago. Irradiated tissue has a poor blood supply and heals unpredictably, which pushes teams away from procedures that rely on the tissue remodeling itself.

Kidney function on that side. A kidney contributing a healthy share of overall function is worth a substantial operation to protect. A kidney that has already lost most of its function changes the calculus entirely, and in some cases the team will discuss whether repair is worthwhile at all.

Prior attempts. A stricture that has already recurred after one or two endoscopic treatments is telling you something about its biology. Most guidelines and expert reviews treat recurrence after endoscopic management as a signal to move toward reconstruction rather than a third dilation.

Layered on top of all five sits the person: overall health, ability to tolerate anesthesia, other conditions, and their own tolerance for either repeated small procedures or one larger recovery. None of these variables is scored on a formula. They are weighed together, in a conversation.

What actually happens during endoscopic widening: balloon dilation for a ureteral stricture, and incision

Endoscopic treatment is done from inside the urinary tract, with no external incision. Under general or spinal anesthesia, the urologist passes a thin telescope called a cystoscope through the urethra into the bladder, finds the opening of the affected ureter, and threads a fine guidewire up past the stricture under X-ray guidance. Everything that follows travels along that wire.

There are two main techniques. In balloon dilation, a deflated balloon on a slim catheter is positioned across the narrowed segment and inflated for a short period, stretching the scar ring apart. In endoureterotomy, meaning a cut made in the ureter wall from the inside, a small blade or laser fiber passed through a ureteroscope, a longer, thinner telescope that enters the ureter itself, makes a controlled incision through the scar so that the tube can heal at a wider diameter. Some surgeons combine both.

Whichever is used, a ureteral stent is almost always left in afterward. The stent acts as an internal scaffold while the widened segment heals around it. How long it stays is a decision for the treating team, but stents are generally intended as temporary devices, kept for days to weeks and not usually beyond a few months without being changed (Cleveland Clinic).

The appeal is obvious. The procedure is typically completed in under an hour, many people go home the same day, and it leaves the door open to reconstruction later if needed. The limitation is equally clear: it treats the scar by remodeling it rather than removing it. For a thin, short, well-vascularized stricture that is a reasonable bet. For a long or dense one, the scar frequently returns once the stent is out, which is why endoscopic management is usually presented as “worth trying first for the right stricture” rather than a definitive fix for every stricture.

What actually happens during reconstructive surgery

Reconstruction takes the opposite philosophy. Instead of persuading scar tissue to behave, the surgeon removes it and restores drainage with healthy tissue. The operation can be done open, through a single larger incision, or laparoscopically or robotically, through several small ports with a camera and long instruments; the robotic approach is now common in centers that offer it, but the underlying repair is the same (Mayo Clinic).

Which repair depends on where the scar sits and how much ureter is missing after it is cut out:

• Ureteroureterostomy: for a short segment, the diseased piece is excised and the two healthy ends are sewn back together over a stent.
• Ureteral reimplantation: for a lower stricture near the bladder, the ureter is detached above the scar and stitched into a fresh opening in the bladder wall.
• Psoas hitch and Boari flap: when the gap to the bladder is too long to bridge directly, the bladder is stitched up to the psoas muscle to bring it closer, or a tongue of bladder wall is fashioned into a tube that reaches upward to meet the ureter.
• Buccal mucosa graft ureteroplasty: a strip of lining from inside the cheek is used as a patch to widen a long or upper stricture without removing the whole segment.
• Ileal ureter: for very long defects, a segment of small bowel is used to replace the ureter altogether.
• Autotransplantation: rarely, the kidney itself is moved down into the pelvis so it can drain directly into the bladder.

A stent and often a small drain are left at the end, and the anastomosis, the surgical join, is checked with imaging before the stent is removed. Reconstruction asks more of the person up front: general anesthesia, a hospital stay, and a longer recovery. In exchange it offers a repair built from healthy tissue rather than remodeled scar, which is why it is the preferred route for strictures that endoscopy is unlikely to hold.

Ureteral stricture endoscopic vs reconstruction: a side-by-side summary

Numbers for durability vary widely between studies and depend heavily on stricture length and cause, so this table deliberately compares what the two approaches involve rather than quoting outcome percentages that would not transfer to your particular scar.

Feature	Endoscopic widening	Reconstructive surgery
What is done	Scar is stretched (balloon) or cut (incision) from inside	Scar is removed or bypassed; drainage rebuilt with healthy tissue
External incisions	None	Several small ports (robotic or laparoscopic) or one open incision
Typical setting	Often day case	Inpatient stay
Best suited to	Short, thin, first-time strictures with good blood supply	Long, dense, recurrent, or radiation-related strictures
Stent afterward	Almost always, temporary	Almost always, temporary
Main limitation	Scar can re-form after stent removal	Larger operation, longer recovery, anesthesia risk
If it fails	Reconstruction remains possible	Revision is more complex
Kidney function needed	Any, but usually reserved for worthwhile kidneys	Generally a kidney worth preserving

Two honest observations about this table. First, the row that matters most is “best suited to,” because almost every disagreement between surgeons about a given case comes down to where a particular stricture falls on that spectrum. Second, the “if it fails” row explains why a stepwise approach, endoscopy first for suitable cases, is so common: it rarely burns bridges. The reverse is not true. A failed reconstruction leaves scar plus surgical change, and the next operation is harder.

What the table cannot show is the person sitting across the desk. Someone with significant heart or lung disease may reasonably accept a higher chance of recurrence to avoid a long anesthetic; someone young with a long working life ahead may prefer one definitive operation over years of stent exchanges. Both are legitimate, and both should be said out loud in clinic (Mayo Clinic; Cleveland Clinic).

Who is usually offered endoscopic treatment first, and who is usually asked to wait?

The classic candidate for a first attempt at endoscopic widening has a short stricture, a kidney that is still doing meaningful work, and a scar that formed from a discrete, non-radiation injury such as a stone or a previous instrument. Add a person who is well enough for a brief anesthetic and who understands that the procedure may need repeating, and most teams will offer this route before anything larger.

Endoscopy is also the pragmatic choice when reconstruction is not yet possible. Someone in the middle of chemotherapy, or recovering from another major operation, or too unwell for a long anesthetic, may be managed with dilation and stents as a bridge, with reconstruction revisited when circumstances change.

Then there is the group asked to wait, and waiting here means something specific. After a fresh injury to the ureter, for example during pelvic surgery, the tissue is inflamed and the true length of the eventual scar cannot be judged. Many teams place a stent or nephrostomy to protect the kidney and deliberately postpone the definitive decision for a period, letting the inflammation settle so that imaging shows the real stricture rather than swollen tissue. Rushing to reconstruct through an inflamed field risks a worse repair.

Similarly, a stricture discovered in a kidney whose function is uncertain usually prompts a functional scan before any repair is chosen. If that scan shows the kidney contributes very little, the conversation may turn to whether it is better to leave it drained by a stent, observe it, or in some circumstances remove it, rather than perform a complex reconstruction to save an organ that is already largely lost (Mayo Clinic). That is a difficult conversation, and a good team will have it early rather than after an operation.

Who is usually steered toward reconstruction?

Several patterns push a team toward rebuilding rather than stretching.

Length. Long strictures are the clearest indication. There is no precise universal cutoff, and different expert groups draw the line at slightly different points, but the principle is consistent: the more scar there is, the less likely dilation is to hold, and the stronger the case for excision or a graft.

Recurrence. A stricture that has closed again after endoscopic treatment is behaving like dense scar, and a second or third dilation is unlikely to change its nature. Most reviews of the topic treat early recurrence as the moment to change strategy.

Radiation history. Tissue that has been irradiated has a compromised blood supply and tends to scar aggressively and heal poorly. Endoscopic incision through such tissue can even make things worse. Reconstructions that bring in fresh, well-vascularized tissue, such as a Boari flap, a buccal graft, or a bowel segment, are generally favored here.

Complete obliteration. Occasionally the ureter is not merely narrowed but entirely blocked, with no channel for a guidewire to pass. Without a lumen there is nothing to dilate, and reconstruction becomes the only reconstructive option.

A young person with a good kidney. When decades of kidney function are at stake, many surgeons and many patients prefer one durable operation over an indefinite cycle of stent changes, each carrying its own small risks and its own recovery.

Fitness for surgery is the balancing weight on the other side. Reconstruction, especially with bowel, is a significant operation, and the anesthetic and surgical risk must be justified by the kidney being protected. This is where the renogram, the kidney function scan, earns its keep: a kidney doing a healthy share of the work is worth the operation, while a kidney doing very little may not be. The team’s job is to put those two numbers, surgical risk and kidney value, honestly side by side.

What the days and weeks afterward usually look like, including robotic ureteral reconstruction recovery

The two paths diverge sharply here, and knowing the shape of each helps people plan work, childcare, and expectations.

After endoscopic widening. Most people wake with a stent in place and go home the same day or the next. The stent, not the procedure, dominates the recovery. Stents commonly cause an urge to urinate more often, mild burning, a dull ache in the flank when the bladder empties, and pink-tinged urine; these are expected and settle once the stent is removed (Cleveland Clinic). Light activity is usually resumed within days. The stent is then removed in clinic or a short procedure on a timeline set by the surgeon, and imaging over the following months checks whether the widened segment has stayed open. That surveillance is not optional: recurrence is often painless.

After reconstruction. Robotic or laparoscopic repair typically involves a hospital stay measured in days, with a urinary catheter and often a small abdominal drain for part of that time. Walking begins early, because mobility lowers the risk of blood clots and chest infection after any abdominal surgery. Port-site discomfort is usually managed with routine measures set by the team. The internal stent stays for a period the surgeon chooses, and the surgical join is often checked with a contrast study before it comes out. Heavier lifting and strenuous exercise are generally restricted for several weeks while the deeper tissues heal; open surgery and bowel-based reconstructions extend that timeline. Specific durations are individual and should come from your own team rather than a general article.

Both paths share a long tail. Follow-up imaging, usually ultrasound and sometimes a repeat renogram, continues for a year or more, because a repair that looks perfect at six weeks can narrow at six months. If you take one thing from this section, let it be that the last follow-up scan is as much a part of the treatment as the operation itself.

Risks and alternatives, in plain clinical terms

Every option carries risk, including the option of doing less. Laying them out neutrally is the only fair way to compare.

Endoscopic widening risks include bleeding, infection, perforation of the ureter wall by the balloon or blade, and, most commonly, simple failure with the stricture re-forming. Repeated procedures accumulate anesthetic exposure and repeated stent periods, each with its own discomfort and small infection risk (Cleveland Clinic).

Reconstructive surgery carries the general risks of abdominal surgery: bleeding, wound or urinary infection, blood clots, injury to nearby organs, and anesthetic complications. Repair-specific risks include leakage of urine at the surgical join, narrowing at the join itself, and, with bladder-flap repairs, changes in bladder capacity. Bowel-based reconstructions add the risks of bowel surgery, mucus in the urine, and longer-term changes in blood chemistry that require monitoring. Buccal grafts add a temporary sore mouth at the donor site.

Alternatives deserve equal airtime. Long-term stenting, with the stent exchanged periodically, keeps the kidney drained without attempting repair; it suits people who are unfit for surgery or whose life expectancy or priorities make a major operation unreasonable, at the cost of ongoing stent symptoms and exchanges (Cleveland Clinic). A permanent nephrostomy tube does the same job externally. And for a kidney that has already lost most of its function, nephrectomy, removal of that kidney, is sometimes the least burdensome path, provided the other kidney is healthy (Mayo Clinic).

The right comparison is not “surgery versus no risk” but “the risk of this repair versus the risk of that one versus the risk of the obstruction itself.” Untreated obstruction has its own price, paid in kidney function and infections (MedlinePlus). A good consent conversation names all three columns.

What is the newest treatment for ureteral strictures? Buccal grafts and robotics, honestly assessed

People searching this question often land on articles about urethral strictures, which is a different tube, addressed in the next section. For the ureter, two developments dominate recent surgical literature, and both deserve a measured description rather than a headline.

Buccal mucosa graft ureteroplasty borrows a technique long used in the urethra. A thin strip of the moist lining inside the cheek is harvested and stitched as an onlay patch over the opened stricture, widening the ureter without removing the segment or sacrificing the ureter’s own blood supply. Its attraction is for long or upper strictures that would otherwise need a bowel segment or autotransplantation. The published experience is growing but remains mostly single-center case series with modest follow-up; there are no large randomized trials comparing it with older reconstructions. That means it is a promising option in experienced hands, not a proven replacement for established repairs.

Robotic reconstruction is less a new operation than a new way of performing established ones, with magnified three-dimensional vision and wristed instruments that make fine suturing deep in the pelvis easier. Studies generally report shorter hospital stays and less blood loss than open surgery, but the repair being sewn is the same repair, and the outcome depends far more on the surgeon’s judgment about which reconstruction to perform than on the platform used (Mayo Clinic).

Techniques under investigation, such as tissue-engineered grafts and drug-coated balloons, remain experimental for the ureter and should be described that way. If a team proposes something newer than the options in this article, reasonable questions are how many of these they have performed, what their own follow-up shows, and what the fallback is if it fails. “Newest” is a description of timing, not of quality, and the honest answer to “which treatment is best” is still “the one matched to your stricture.”

What people often get wrong about ureteral stricture treatment options

“Ureteral and urethral are the same thing.” They are not, and search engines blur them constantly. The ureters run from kidney to bladder; the urethra runs from the bladder out of the body. Urethral strictures are far more common, are treated with different procedures, and most of the online material about “how painful is stricture surgery” refers to them. If your report says ureteral, filter what you read accordingly.

“If it does not hurt, it cannot be doing harm.” Chronic obstruction is frequently painless. Pain tends to come from sudden blockage or infection; slow scarring can quietly cost kidney function while you feel fine (MedlinePlus; NHS).

“A stent has fixed it.” A stent is a scaffold or a bridge. It keeps urine flowing while the real decision is made, and stents are designed to be temporary (Cleveland Clinic). Leaving one in and forgetting about it is a well-recognized way to end up with encrusted stents, infections, and a harder repair later.

“Endoscopic means minor, so it must be safer overall.” Per procedure, yes. Over years, a cycle of repeated dilations, stent exchanges, and anesthetics carries its own cumulative burden, and a stricture that keeps recurring may be better served by one reconstruction.

“Reconstruction is a last resort.” For long, dense, or radiation-related strictures it is often the first-line recommendation, because the alternative is predictable failure.

“Once the scan looks good, I am done.” Recurrence can appear many months after either treatment. Missing follow-up imaging is one of the most avoidable reasons people present again with a damaged kidney.

“The robot does the operation.” It does not. It is an instrument controlled entirely by the surgeon, and the choice of repair remains a human judgment.

None of these errors is foolish. Most come from perfectly reasonable reading applied to the wrong tube or the wrong timescale.

Questions to ask your care team

A twenty-minute clinic slot goes further with a written list. These are the questions that tend to change plans or clarify them.

• How long is my stricture, and where exactly along the ureter is it? Which third?
• What do you think caused it, and does that cause affect which repair you would recommend?
• How much function does the affected kidney have compared with the other one, and has that been measured with a renogram?
• Are you recommending endoscopic treatment first, reconstruction first, or a period of drainage while we wait for tissue to settle? What is the reasoning?
• If we start with endoscopic widening and it recurs, what would the next step be, and does trying it first make reconstruction harder later?
• If you are recommending reconstruction, which specific repair, and why that one for my location and length?
• Will the operation be open, laparoscopic, or robotic, and does that change anything about the repair itself or the recovery?
• How long would I expect to have a stent, and what symptoms from the stent should I expect versus report?
• What is the follow-up schedule, and which scans will tell us the repair is holding?
• What are the alternatives if I decide not to have surgery, including long-term stenting or observation, and what are the risks of each for my kidney?
• Is there anything about my other health conditions or medicines that changes the balance between the options? (Decisions about starting, stopping, or adjusting any medicine belong with the prescribing clinician.)
• Who do I call, and at what number, if something worries me after I go home?

Bring someone with you if you can, and ask whether the discussion can be summarized in your clinic letter. The choice between endoscopic and reconstructive repair is one where understanding the “why” genuinely helps people live comfortably with the “what,” especially if the first attempt needs revising.

When to call your doctor

Whether you are waiting for a decision, living with a stent, or recovering from either kind of repair, some signs should not wait for the next scheduled appointment. Contact your care team promptly, or seek urgent care, if you notice any of the following (NHS; Mayo Clinic; Cleveland Clinic):

• Fever, chills, or shaking, particularly alongside flank or back pain. An infected, obstructed kidney can progress to sepsis quickly, and this combination is treated as an emergency.
• Severe or rapidly worsening pain in the flank, abdomen, or side that is not controlled by the measures your team advised.
• Passing very little or no urine, or a marked drop in the amount you usually pass, especially if you have only one working kidney.
• Heavy bleeding in the urine: clots, or urine that is dark red rather than faintly pink, or bleeding that gets heavier rather than lighter.
• Persistent nausea and vomiting that prevents you from keeping fluids down.
• After surgery: redness, swelling, or discharge from a wound; a drain or catheter that stops draining; sudden abdominal distension; calf pain or swelling; shortness of breath or chest pain, which can signal a blood clot and need emergency assessment.
• Stent-related: symptoms that were tolerable and suddenly change, or a stent that appears to have moved or partially come out.
• Feeling generally unwell in a way that frightens you, confused, drowsy, or unusually breathless.

Mild burning, urinary frequency, and a dull flank ache with a stent in place are expected and usually settle once it is removed. The distinction that matters is trend and company: symptoms that escalate, or that arrive with fever, deserve a call. When in doubt, ring. Urology teams would far rather hear about a false alarm than see an obstructed, infected kidney the next day. Every decision about what to do next, including whether the plan needs to change, belongs with your treating team.

Frequently asked questions

Which treatment is best for a ureteral stricture, endoscopic or reconstruction?

Neither is best in general; the right one depends on the stricture. Short, thin, first-time strictures above a well-functioning kidney are often treated endoscopically first, while long, dense, recurrent, or radiation-related strictures are usually referred for reconstruction. Your urology team weighs length, location, cause, kidney function, prior attempts, and your overall health before recommending a route, and the decision sits with them and you together.

Is a ureteral stricture serious?

It can be. The concern is not the narrowing itself but the pressure it creates in the kidney above it, which can lead to infection and gradual, sometimes permanent, loss of that kidney’s function. Most strictures are found before serious damage occurs, and drainage with a stent or nephrostomy relieves pressure quickly while a definitive plan is made. Fever with flank pain in someone with a known stricture is an emergency.

How does balloon dilation for a ureteral stricture work?

A guidewire is passed up the ureter through a telescope in the bladder, a slim deflated balloon is positioned across the narrowed segment, and the balloon is inflated to stretch the scar ring apart. A temporary stent is then left in place as a scaffold while the widened area heals. It is done under anesthesia, usually as a day case, and suits short strictures best; longer ones frequently narrow again after the stent comes out.

What is the newest treatment for ureteral strictures?

The most discussed recent developments are buccal mucosa graft ureteroplasty, which patches a long stricture with lining taken from inside the cheek, and robotic platforms for performing established reconstructions. Both are promising in experienced hands, but the evidence consists mainly of case series rather than large randomized trials. Newer does not automatically mean better; the best repair is still the one matched to your stricture’s length, location, and cause.

How painful is ureteral stricture surgery?

Pain after endoscopic widening is usually mild and comes mostly from the stent, which can cause flank ache, urgency, and burning until it is removed. Reconstructive surgery involves incisions and a hospital stay, so discomfort is greater in the first days, though robotic and laparoscopic approaches generally involve less than open surgery. Pain control is planned by your team; severe or escalating pain, or pain with fever, should always be reported.

What does robotic ureteral reconstruction recovery involve?

Expect a hospital stay of several days with a urinary catheter and often a small drain at first, early walking to reduce clot risk, and an internal stent left for a period your surgeon sets. Strenuous activity and heavy lifting are restricted for some weeks while deeper tissues heal, and imaging checks the surgical join before the stent is removed. Exact timelines vary by repair type and should come from your own team.

Can a ureteral stricture come back after treatment?

Yes, after either approach. Recurrence is more common after endoscopic widening, especially for longer strictures, because the scar is remodeled rather than removed. Narrowing can also develop at the surgical join after reconstruction. Because recurrence is often painless, follow-up imaging for a year or longer is a standard part of care, and skipping those scans is one of the most avoidable ways a kidney is lost.

What are the ureteral stricture treatment options if I cannot have surgery?

Long-term stenting, with the stent exchanged periodically, keeps the kidney drained without a formal repair, at the cost of ongoing stent symptoms and regular procedures. A nephrostomy tube through the back does the same job externally. For a kidney that has already lost most of its function, observation or removal of that kidney may be discussed if the other is healthy. Your team will weigh these against the risk of untreated obstruction.

Why did my surgeon suggest waiting before repairing my ureteral stricture?

After a recent injury to the ureter, the tissue is inflamed and the true length of the eventual scar cannot be judged accurately. Many teams place a stent or nephrostomy to protect the kidney and deliberately delay the definitive decision until inflammation settles, so imaging shows the real stricture. Operating through an inflamed field risks a worse repair. Waiting in this context is a planned step, not neglect.

Is a ureteral stricture the same as a urethral stricture?

No. The ureters carry urine from each kidney to the bladder; the urethra carries it from the bladder out of the body. Urethral strictures are more common, are treated with different procedures such as urethrotomy or urethroplasty, and account for much of what appears online about stricture surgery. If your report says ureteral, information about urethral strictures does not apply, including most figures about pain and recovery.
