N35.91 Urethral stricture, unspecified, male

Name of the Condition

• Urethral stricture, unspecified, male
• ICD-10 Code: N35.91

Summary

Urethral stricture, unspecified, male refers to a narrowing of the urethra in males that is not further specified by location. This condition can obstruct urine flow and lead to urinary symptoms. The stricture may result from scarring or inflammation, which reduces the urethral diameter over time.

Causes

Urethral stricture can develop due to scarring from injury, infection, inflammation, or previous medical procedures involving the urethra. Trauma, surgery, or chronic inflammation may contribute to the formation of scar tissue that narrows the urethra.

Risk Factors

• History of urethral injury or trauma
• Recurrent urinary tract infections
• Prolonged catheterization or instrumentation
• Inflammatory conditions affecting the urethra
• Previous urethral surgery or procedures

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. Intermittent self-catheterization may also be used to maintain patency.

Prognosis and Follow-Up

With appropriate treatment, patients can experience significant symptom relief. Regular follow-up is important to monitor for recurrence or complications, as strictures may redevelop over time.

Complications

• Urinary retention
• Recurrent urinary tract infections
• Kidney damage from prolonged obstruction
• Bladder dysfunction

Lifestyle & Prevention

• Stay hydrated to promote urine flow
• Practice safe sex to reduce infection risk
• Avoid unnecessary urethral instrumentation
• Seek prompt treatment for urethral injuries or infections

When to Seek Professional Help

Consult a healthcare provider if you experience persistent difficulty urinating, pain during urination, or signs of urinary retention. Early evaluation can prevent complications.

Tips for Medical Coders

Document the location and cause of the stricture when available, as this may impact coding specificity. For N35.91, ensure the diagnosis is confirmed and the unspecified nature of the stricture is clearly noted in the medical record.
