N35.1

Clinical Causes: Previous urinary tract infections (UTIs), especially if recurrent or severe Sexually transmitted infections such as gonorrhea or chlamydia Injury to the urethra due to trauma or catheter use Involvement of scarring from inflammation or infection Certain surgical procedures around the urinary tract

Key Symptoms: A weak or slow urine stream Difficulty starting urination Frequent urination or a persistent urge to urinate Pain or a burning sensation during urination The feeling of incomplete bladder emptying Urinary retention in severe cases Blood in the urine

Diagnosis Path: To diagnose postinfective urethral stricture, healthcare professionals typically perform a combination of clinical assessments and diagnostic tests. These may include: - **Physical Examination:** Checking for any palpable abnormalities or tenderness. - **Urinalysis:** Detecting signs of infection or blood. - **Post-Void Residual Measurement:** Assessing how much urine remains in the bladder after urination. - **Uroflowmetry:** Measuring the flow rate of urine. - **Retrograde Urethrogram:** An imaging test where contrast dye is injected into the urethra to visualize narrowing or blockages. - **Cystoscopy:** A procedure where a thin camera is inserted into the urethra to directly observe the interior. Accurate diagnosis helps determine the severity and location of the stricture, guiding appropriate treatment.

Treatment Protocols: Treatment options for postinfective urethral stricture aim to restore normal urine flow and alleviate symptoms. These include: - **Dilation:** Gradually stretching the narrowed section of the urethra using specialized instruments. - **Urethrotomy:** A surgical procedure to cut the scar tissue causing the stricture. - **Urethroplasty:** A more extensive surgery to remove the narrowed segment and reconnect the healthy ends. Often used for complex or recurrent strictures. - **Catheterization:** Temporary placement of a catheter to manage urine flow during healing. - **Antibiotic Therapy:** If active infection is present, appropriate antibiotics are prescribed. Post-treatment, regular follow-up is essential to monitor for recurrence. Preventive measures include prompt treatment of urinary tract infections and avoiding urethral trauma whenever possible.
