Key Takeaways
Urethral stricture is a narrowing of the urethra that blocks normal urine flow
Most cases develop from injury, infection, or inflammation of the urethral tissue
Symptoms include difficulty urinating, weak stream, and frequent urinary tract infections
Treatment ranges from gentle dilation to surgical reconstruction depending on severity
Early diagnosis and appropriate treatment can relieve symptoms and reduce the risk of complications, including bladder or kidney damage in severe cases.
Overview
Urethral stricture is a condition where the tube that carries urine from the bladder out of the body becomes narrow. This narrowing blocks the normal flow of urine. The urethra can become scarred from injury, infection, or other causes.
Men are much more likely to develop urethral strictures than women. This happens because men have a longer urethra that passes through the prostate and penis. Urethral strictures are uncommon, but they occur much more often in men than in women.
When urine cannot flow freely, it can cause serious problems. The bladder may not empty completely, leading to infections. Over time, backed-up urine can damage the kidneys and bladder. Without treatment, strictures can get worse and make daily activities difficult. The good news is that many effective treatments can help restore normal urine flow. Doctors have many options to choose from based on each person's needs.
Symptoms & Signs
Urethral stricture symptoms often develop gradually, although some people may notice symptoms suddenly or first seek care because they cannot urinate. Many people notice changes in their urinary habits before other symptoms appear. Early recognition of these signs helps doctors start treatment quickly.
Primary Symptoms
Weak or slow urine stream that may stop and start
Difficulty starting urination or feeling like you cannot empty your bladder completely
Frequent urinary tract infections with burning, pain, or blood in urine
Spraying or splitting of the urine stream during urination
When to Seek Care
See a doctor if you have trouble urinating or notice changes in your urine stream. Some men feel pain in the lower belly or between the scrotum and anus. You should also see a doctor if you keep getting urinary tract infections. Understanding allergies and other medical conditions can sometimes affect urinary symptoms too.
When to Seek Immediate Care
Get emergency medical help if you cannot urinate at all, have severe pain, or develop a fever with urinary symptoms.
Causes & Risk Factors
Age
Most common in men over 40, though can occur at any age
Genetics
Most urethral strictures are linked to injury, inflammation, infection, medical procedures, or an unknown cause.
Lifestyle
Sex without barrier protection, previous sexually transmitted infections, and activities or jobs that carry a risk of pelvic injury
Other Conditions
Previous sexually transmitted infections, pelvic or urethral injury, or a history of procedures involving the urethra

Diagnosis
Medical History & Physical Examination
Your doctor will ask about your symptoms and medical history. They want to know when urinary problems started and how they have changed over time. Previous injuries, infections, or medical procedures are important clues.
During the physical exam, your doctor will check your abdomen and genital area. They may feel for an enlarged bladder or tender areas. This examination helps identify possible causes and complications.
Diagnostic Testing
Urine flow study measures how fast and how much urine you can pass in a given time
Retrograde urethrogram uses contrast dye and X-rays to see the inside of the urethra
Cystoscopy involves inserting a thin, flexible camera through the urethra to directly view the narrowing
Ultrasound imaging can show bladder emptying and detect retained urine

Treatment Options
Treatment goals focus on restoring normal urine flow and preventing complications. The best approach depends on the location, length, and severity of the stricture. Your doctor will recommend the best option for your specific situation.
Conservative Treatments
Urethral dilation uses special instruments to gently stretch the narrowed area
For selected patients, a clinician may recommend intermittent self-catheterization and teach them how to do it safely to help keep the urethra open after treatment.
Medications can treat infections and reduce inflammation, though they do not cure strictures
Lifestyle changes like avoiding irritants and managing underlying conditions may help
Advanced Treatments
Urethroplasty surgery removes the scarred section and reconnects healthy tissue
Urethrotomy uses an instrument passed through the urethra to cut the scar tissue. In selected cases, a clinician may use an additional treatment intended to reduce recurrence.
Tissue grafts from other parts of the body can be used to reconstruct longer strictures

Daily Management Strategies
Drink enough fluid to avoid dehydration unless your healthcare professional has told you to limit fluids. Hydration may support urinary health, but it does not treat a stricture or a urinary infection. Avoid holding urine for long periods, as this can worsen bladder problems.
Practice good hygiene, especially around the genital area. Use mild, unscented soaps and avoid harsh chemicals. Some men find that certain positions during urination help improve flow. Sitting down to urinate sometimes helps the bladder empty more completely.
Keep track of your symptoms in a diary. Note changes in urine stream, frequency, or any pain. This information helps your doctor monitor your condition and adjust treatment. Sharing this diary with your healthcare team leads to better care decisions.
Monitor for signs of infection like burning, blood in urine, or fever. Contact your doctor right away if these symptoms appear. Seek urgent medical advice for fever with urinary symptoms, worsening pain, or difficulty passing urine; get emergency help if you cannot urinate.
Exercise & Movement
Regular physical activity supports overall health and may improve blood flow to healing tissues. Low-impact exercises like walking, swimming, or cycling are generally safe. Avoid activities with high risk of pelvic injury, such as contact sports or horseback riding. Always talk to your doctor before starting new exercises after treatment.
Pelvic floor exercises do not open a scarred urethra, but a clinician or pelvic-floor therapist may recommend them for certain other urinary symptoms. However, check with your doctor before starting any new exercise program, especially after surgery.
Prevention
Practice safe sex to reduce the risk of sexually transmitted infections that can cause urethral inflammation
Use proper protective equipment during sports and occupational activities to prevent pelvic injuries
Avoid using harsh chemicals, soaps, or products near the genital area that could irritate the urethra
Seek medical care for symptoms of a urinary tract infection or sexually transmitted infection so the cause can be diagnosed and treated appropriately.
Frequently Asked Questions
A true scar-related urethral stricture usually does not go away on its own. Treatment depends on the symptoms, degree of obstruction, and risk of complications; early evaluation can help prevent worsening problems.
Yes, but it is much less common in women because they have a shorter urethra. When strictures do occur in women, they are often related to previous surgery, trauma, or infections. In women, diagnosis may require evaluation by a clinician experienced with female urinary disorders because other conditions can cause similar symptoms.
Surgery success rates vary with the procedure used, the stricture's location and length, previous treatments, and how success is defined. Ask your surgeon about expected outcomes for your specific case. Choosing a procedure requires careful evaluation of the stricture and the person's overall health and treatment goals.
Some treatments like dilation may need to be repeated if the stricture returns. Surgery, especially urethroplasty, often provides long-lasting results. Your doctor will monitor you regularly to catch any recurrence early.
Yes, if left untreated, urethral strictures can cause urine to back up into the kidneys. This can lead to kidney damage over time. If obstruction is severe or prolonged, a clinician may use blood tests and imaging to check kidney function and look for urinary backup.
