N35.1 Postinfective urethral stricture, not elsewhere classified

Name of the Condition

• Postinfective urethral stricture, not elsewhere classified

Summary

Postinfective urethral stricture is a narrowing of the urethra resulting from scarring caused by a prior infection. This condition can obstruct urine flow and lead to urinary symptoms. The stricture is classified here when it does not fall under other specified subcategories.

Causes

The condition develops due to scarring from infections affecting the urethra, such as sexually transmitted infections or other bacterial infections. Inflammation from these infections can lead to tissue damage and subsequent narrowing of the urethral passage.

Risk Factors

• History of urethral infections
• Recurrent or untreated urinary tract infections
• Prolonged catheterization or instrumentation
• Inflammatory conditions involving the urethra

Symptoms

• Difficulty initiating urination
• Weak or intermittent urine stream
• Increased frequency or urgency of urination
• Painful urination or discomfort
• Urinary retention or incomplete bladder emptying

Diagnosis

Diagnosis typically involves a physical examination, uroflowmetry to assess urine flow, and imaging studies such as retrograde urethrogram or cystoscopy to visualize the stricture. These methods help determine the location and severity of the narrowing.

Treatment Options

Treatment may include urethral dilation to temporarily widen the stricture, urethrotomy to cut the scar tissue, or surgical reconstruction (urethroplasty) for more severe cases. The choice of treatment depends on the stricture's location and severity.

Prognosis and Follow-Up

With appropriate treatment, many patients experience improved urine flow. However, strictures may recur, requiring ongoing monitoring. Regular follow-up with a healthcare provider is recommended to assess symptoms and adjust treatment as needed.

Complications

• Recurrent urinary tract infections
• Urinary retention or incomplete bladder emptying
• Kidney damage from prolonged obstruction
• Increased risk of stricture recurrence

Lifestyle & Prevention

• Practice safe sex to reduce the risk of sexually transmitted infections.
• Seek prompt treatment for urethral infections to minimize scarring.
• Avoid unnecessary urethral instrumentation when possible.
• Stay hydrated to support urinary tract health.

When to Seek Professional Help

Consult a healthcare provider if you experience persistent urinary symptoms, such as difficulty urinating, pain, or frequent infections. Early evaluation can help prevent complications and guide appropriate management.

Tips for Medical Coders

When coding for postinfective urethral stricture, ensure the documentation supports the infectious etiology and confirms the stricture is not classified elsewhere. Verify that the medical record specifies the condition as postinfective and not due to trauma or other causes. Accurate documentation of the stricture's location and severity may be required for appropriate coding.
