N35 Urethral stricture

Name of the Condition

• Urethral stricture

Summary

Urethral stricture is a condition characterized by the narrowing of the urethra, which can impede the flow of urine. This narrowing may result from scarring or inflammation, leading to urinary symptoms and potential complications.

Causes

Urethral stricture can develop due to various factors, including trauma, infection, inflammation, or previous medical procedures involving the urethra. Scarring from these events can reduce the urethral diameter over time.

Risk Factors

• History of urethral injury or trauma
• Recurrent urinary tract 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 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 location, length, and underlying cause.

Prognosis and Follow-Up

The prognosis varies based on the stricture's severity and treatment. Recurrence is possible, especially with conservative treatments. Regular follow-up is recommended to monitor for symptoms and assess the need for further intervention.

Complications

Untreated or recurrent strictures can lead to urinary retention, kidney damage, or recurrent infections. Chronic obstruction may also increase the risk of bladder or kidney stones.

Lifestyle & Prevention

• Stay hydrated to promote urine flow
• Practice safe catheterization techniques if needed
• Address urinary tract infections promptly
• Avoid activities that may cause urethral trauma

When to Seek Professional Help

Seek medical attention if you experience persistent difficulty urinating, pain, or signs of infection (e.g., fever, cloudy urine). Prompt evaluation can prevent complications and guide appropriate treatment.

Tips for Medical Coders

When coding for urethral stricture (ICD-10-CM code N35), ensure documentation specifies the stricture's location, cause (e.g., post-traumatic, inflammatory), and any associated complications. Accurate clinical details support precise code assignment and reimbursement.
