N35.913 Unspecified membranous urethral stricture, male

Name of the Condition

• Unspecified membranous urethral stricture, male
• ICD-10 Code: N35.913

Summary

Unspecified membranous urethral stricture, male refers to a narrowing of the membranous portion of the urethra in males. This condition can obstruct urine flow and may lead to urinary symptoms or complications. The stricture results from scarring or inflammation that 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

• Urethral dilation to temporarily widen the stricture
• Urethrotomy to cut scar tissue
• Surgical reconstruction (urethroplasty) for severe cases
• Intermittent self-catheterization to maintain patency

Prognosis and Follow-Up

Early treatment often leads to good outcomes with minimal complications. Regular follow-up with a urologist may be necessary to monitor for recurrence or progression.

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
• Promptly treat urinary tract infections

When to Seek Professional Help

Seek medical attention if you experience difficulty urinating, pain during urination, or signs of urinary retention. These symptoms may indicate a serious obstruction requiring evaluation.

Tips for Medical Coders

Document the location (membranous urethra) and specify if the stricture is unspecified. Ensure clinical documentation supports the diagnosis and any associated procedures or complications.
