N35.012 Post-traumatic membranous urethral stricture

Name of the Condition

• Post-traumatic membranous urethral stricture
• ICD-10-CM Code: N35.012

Summary

Post-traumatic membranous urethral stricture is a condition characterized by the narrowing of the membranous portion of the urethra due to injury or trauma. This narrowing can obstruct urine flow and lead to urinary symptoms.

Causes

Direct trauma to the pelvic region or urethra, such as from pelvic fractures, falls, or penetrating injuries. Previous surgical procedures involving the urethra or pelvic organs. Prolonged catheterization or instrumentation of the urethra.

Risk Factors

• History of pelvic or urethral trauma.
• Prior surgeries affecting the urinary tract.
• Repeated urethral catheterization or instrumentation.
• Engaging in high-risk activities that may result in pelvic injury.

Symptoms

• Difficulty initiating urination or weak urine stream.
• Increased frequency or urgency of urination.
• Painful urination or discomfort in the pelvic region.
• Urinary retention or incomplete bladder emptying.
• Recurrent urinary tract infections.

Diagnosis

Diagnosis involves a combination of clinical evaluation and imaging studies. A physical examination may reveal signs of urethral obstruction. Uroflowmetry assesses urine flow rate, while cystoscopy or urethroscopy allows direct visualization of the stricture. Imaging studies, such as retrograde urethrogram or voiding cystourethrogram, help identify the location and severity of the narrowing.

Treatment Options

• Dilation: Temporary widening of the stricture using specialized instruments.
• Urethrotomy: Endoscopic procedure to incise the stricture and improve urine flow.
• Surgical Reconstruction: Urethroplasty or other reconstructive techniques for severe or recurrent cases.

Prognosis and Follow-Up

The prognosis depends on the severity of the stricture and the chosen treatment. Recurrence is possible, especially with conservative treatments. Regular follow-up appointments are recommended to monitor for symptoms, assess urine flow, and detect recurrence early.

Complications

• Recurrent stricture formation.
• Chronic urinary retention or incontinence.
• Urinary tract infections.
• Kidney damage due to prolonged obstruction.

Lifestyle & Prevention

• Avoid activities that increase the risk of pelvic trauma.
• Ensure proper medical care for pelvic injuries to minimize urethral damage.
• Follow post-procedure guidelines to reduce the risk of stricture recurrence.

When to Seek Professional Help

Seek medical attention if you experience persistent difficulty urinating, pain during urination, blood in the urine, or signs of urinary tract infection. Prompt evaluation is important to prevent complications.

Tips for Medical Coders

When coding for post-traumatic membranous urethral stricture (N35.012), ensure documentation specifies the membranous urethra as the site of the stricture and confirms a traumatic etiology. Include details about the nature of the trauma, diagnostic findings, and treatment provided to support accurate code assignment.
