Kidney Stones in Men: Symptoms, Causes, and When to Seek Care

Kidney stones in men are a common urinary problem that can cause sudden pain, urinary symptoms, and sometimes complications if a stone blocks urine flow. Understanding the symptoms, causes, and treatment options can help men seek care at the right time and reduce the chance of future stones.

Overview

Kidney stones are hard deposits made of minerals and salts that form inside the kidneys. They can stay in the kidney or move into the ureter, the tube that carries urine from the kidney to the bladder. When a stone travels or causes a blockage, it may lead to sudden and intense discomfort.

Kidney stones can affect anyone, but they are often discussed in men’s health because men have historically had a higher risk of developing them. Risk can vary with age, diet, hydration, body weight, family history, and certain medical conditions. A man who has had one stone is also more likely to develop another in the future.

Stones are not all the same. The most common types are calcium stones, followed by uric acid stones, struvite stones, and cystine stones. Knowing the stone type can help guide prevention, because the causes and long-term management may differ from one person to another.

Symptoms of Kidney Stones in Men

The most well-known symptom is sudden pain that may begin in the side, back, or below the ribs. This pain can move toward the lower abdomen, groin, or testicular area as the stone travels. It may come in waves, changing in intensity over time as the urinary tract contracts around the stone.

Other common symptoms include burning or pain during urination, a frequent urge to urinate, passing small amounts of urine, or seeing pink, red, or brown urine from blood. Urine may also look cloudy or have an unusual odor, especially if irritation or infection is present.

Some men also experience nausea and vomiting because kidney stone pain can trigger a strong body-wide stress response. Small stones may occasionally pass with only mild symptoms, while larger stones or those causing blockage are more likely to produce noticeable pain and urinary changes.

• Sharp pain in the back, side, lower abdomen, or groin
• Blood in the urine
• Painful urination
• Urgent or frequent urination
• Nausea or vomiting
• Cloudy or foul-smelling urine

Causes and Risk Factors

Kidney stones develop when substances in the urine, such as calcium, oxalate, or uric acid, become concentrated enough to form crystals. If there is not enough fluid in the urine to dilute these substances, crystals can stick together and grow into a stone. Low fluid intake is one of the most important and preventable risk factors.

Diet can play a role, though the exact triggers differ by stone type. A diet high in salt may increase calcium in the urine. High intake of animal protein can contribute to uric acid stones in some people. Certain foods high in oxalate may matter for people prone to calcium oxalate stones, especially if fluid intake is low.

Medical conditions can also raise risk. These include obesity, gout, recurrent urinary tract infections, bowel disease, some kidney disorders, and conditions that change the body’s acid-base balance, such as renal tubular acidosis. Family history matters as well, and some people have a hereditary tendency to stone formation. In men with repeated stones, a specialist may also evaluate for broader kidney or genetic factors when appropriate.

How Kidney Stones Are Diagnosed

Diagnosis usually begins with a medical history and physical examination. The doctor asks about the location and pattern of pain, urinary symptoms, past stone episodes, diet, medicines, and family history. Because several conditions can mimic kidney stone pain, the goal is to confirm the stone and check for complications such as infection or obstruction.

Urine and blood tests are commonly used. A urine test may show blood, crystals, or signs of infection, while blood tests can help assess kidney function and measure substances linked to stone formation. If a stone is passed, it may be collected and analyzed to determine its composition.

Imaging is often needed to locate the stone and estimate its size. Ultrasound may be used first in many situations and can be part of renal ultrasonography for the urinary system. In some cases, especially when more detail is needed, CT imaging through CT and MRI for urology can help identify the stone and evaluate the degree of blockage.

Treatment Options

Treatment depends on the size, location, and type of stone, as well as the severity of symptoms. Small stones often pass on their own with time, fluids, pain relief, and close follow-up. Doctors may also prescribe medicines that help relax the ureter, making it easier for some stones to pass.

When a stone is too large to pass, causes ongoing severe pain, blocks urine flow, damages kidney function, or occurs with infection, a procedure may be needed. One common noninvasive option is shock wave lithotripsy, which uses sound waves to break certain stones into smaller fragments. Other procedures may be recommended depending on where the stone is located and how complex the case is.

Men with repeated stones may benefit from a more detailed evaluation and prevention plan, sometimes within a dedicated nephrolithiasis program. If infection is suspected, it is treated promptly because a blocked urinary tract with infection can become serious. The aim of treatment is not only to relieve current symptoms but also to reduce the risk of future stone episodes.

Prevention and Self-Care

The most effective general prevention step is staying well hydrated. Drinking enough fluid helps dilute the urine so crystals are less likely to form. The exact amount varies from person to person, but many men are advised to drink regularly throughout the day and increase intake in hot weather, during exercise, or whenever sweating is heavy.

Dietary prevention should be individualized rather than overly restrictive. Lowering excess salt intake, avoiding dehydration, and discussing protein balance with a doctor or dietitian may help. In many cases, maintaining a normal dietary calcium intake is still important, because cutting calcium too much can sometimes increase oxalate absorption and may not prevent stones.

Weight management, regular follow-up, and treatment of related conditions also matter. Men with recurrent stones may be advised to complete a metabolic evaluation, which can include urine and blood testing to identify personal triggers. Taking prescribed preventive medicines consistently, if recommended, can significantly support long-term stone prevention.

When to Seek Medical Care

Medical assessment is important for any first episode of suspected kidney stones, especially when pain is strong or symptoms are unclear. Because pain in the side, back, or lower abdomen can have several causes, a proper diagnosis helps rule out other urgent conditions and ensures the most suitable treatment plan.

Urgent care is needed if there is fever, chills, severe or uncontrolled pain, persistent vomiting, difficulty passing urine, little or no urine output, or signs of dehydration. These symptoms can suggest infection, significant blockage, or another complication that should not be managed at home.

Men who keep getting stones should also see a specialist even if symptoms eventually settle. Recurrent stones can affect quality of life and may point to an underlying metabolic or urinary problem. Near the end of the care pathway, it may also be reassuring to know that Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat kidney stone disease for international patients.

Frequently asked questions

Are kidney stones more common in men?

Kidney stones have historically been more common in men, although they can affect people of any sex. Risk depends on several factors, including hydration, diet, weight, family history, and certain medical conditions.

What does kidney stone pain feel like in men?

Kidney stone pain is often described as sharp, cramping, or wave-like pain in the side or back. It may move toward the lower abdomen, groin, or testicular area as the stone travels through the urinary tract.

Can a kidney stone go away on its own?

Yes, many small stones pass on their own with fluids, time, and symptom management. However, a doctor should assess the situation to determine the stone’s size and location and to make sure there is no infection or significant blockage.

How long does it take to pass a kidney stone?

The time varies widely depending on the stone’s size, shape, and location. Some stones pass within days, while others can take weeks or require a procedure if they do not move or if symptoms worsen.

When is a kidney stone an emergency?

A kidney stone needs urgent care if it causes fever, chills, severe pain, repeated vomiting, or difficulty passing urine. These signs may indicate infection or blockage, which can require prompt treatment.

Can kidney stones be prevented from coming back?

In many cases, yes. Drinking enough fluid, reducing excess salt, addressing medical risk factors, and following a doctor’s prevention plan can lower the chance of recurrence.
