N35.813 Other membranous urethral stricture, male

Name of the Condition

• Other membranous urethral stricture, male

Summary

Other membranous urethral stricture, male, refers to the narrowing of the membranous portion of the male urethra due to causes not classified under more specific subcategories. This narrowing can obstruct urine flow and lead to urinary symptoms. The condition is distinguished by its etiology, which does not fall into the post-traumatic or postinfective categories.

Causes

The stricture may result from various non-traumatic, non-infectious factors, including chronic inflammation, iatrogenic injury (e.g., from medical procedures), or congenital abnormalities. Scarring from these events can reduce the urethral diameter over time.

Risk Factors

• History of urethral procedures or instrumentation
• Chronic inflammatory conditions affecting the urethra
• Congenital urethral abnormalities
• Prolonged catheterization or urethral manipulation

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 combination of 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 length, location, and underlying cause.

Prognosis and Follow-Up

Prognosis varies based on the stricture's severity and treatment response. Recurrence is possible, especially with conservative treatments. Regular follow-up may be necessary to monitor for recurrence or complications.

Complications

• Recurrent urinary tract infections
• Urinary retention or incontinence
• Kidney damage due to prolonged obstruction
• Sexual dysfunction

Lifestyle & Prevention

• Stay hydrated to promote urine flow
• Avoid prolonged catheter use when possible
• Seek prompt treatment for urethral injuries or infections
• Follow post-procedure care instructions to reduce scarring

When to Seek Professional Help

Seek medical attention if you experience persistent urinary symptoms, pain, or difficulty urinating. Immediate care is needed for signs of urinary retention or infection.

Tips for Medical Coders

Document the location (membranous urethra) and exclude post-traumatic or postinfective causes. Ensure clinical notes support the diagnosis and specify any contributing factors to justify the code.
