N35.113 Postinfective membranous urethral stricture, not elsewhere classified, male

Name of the Condition

• Postinfective membranous urethral stricture, not elsewhere classified, male

Summary

Postinfective membranous urethral stricture, not elsewhere classified, male, is a condition where the male urethra narrows due to scarring from a prior infection, specifically affecting the membranous portion. This narrowing can obstruct urine flow and cause urinary symptoms.

Causes

The condition develops from scarring of the membranous urethra following an infection, such as a sexually transmitted infection or other bacterial urethritis. Inflammation from the infection leads to tissue damage and subsequent stricture formation in this specific segment.

Risk Factors

• History of urethral infections
• Recurrent or untreated sexually transmitted infections
• Prolonged catheterization or instrumentation
• Inflammatory conditions affecting 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 and may include urethroscopy to visualize the stricture, uroflowmetry to assess urine flow, or imaging studies like retrograde urethrogram to evaluate the narrowing. These methods help determine the location and severity of the stricture.

Treatment Options

• Dilation: Gradual widening of the stricture using instruments.
• Urethrotomy: Endoscopic procedure to cut the stricture.
• Urethroplasty: Surgical reconstruction of the urethra.

Prognosis and Follow-Up

Prognosis depends on the stricture's severity and treatment response. Regular follow-up may be necessary to monitor for recurrence or complications. Treatment success varies, and some cases may require repeated interventions.

Complications

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

Lifestyle & Prevention

• Practice safe sex to reduce infection risk.
• Seek prompt treatment for urethral infections.
• Avoid unnecessary urethral instrumentation when possible.

When to Seek Professional Help

Consult a healthcare provider if you experience persistent urinary symptoms, pain, or difficulty urinating. Early evaluation can prevent complications.

Tips for Medical Coders

Document the specific location (membranous urethra) and confirm the stricture is postinfective and not classified elsewhere. Ensure clinical notes support the diagnosis to justify code assignment.
