N99.115 Postprocedural fossa navicularis urethral stricture

Name of the Condition

• Postprocedural fossa navicularis urethral stricture

Summary

Postprocedural fossa navicularis urethral stricture is a narrowing of the urethra in the fossa navicularis region that occurs as a complication following a medical procedure. This narrowing can obstruct urinary flow and may cause associated symptoms.

Causes

This condition typically develops after procedures involving the urethra or surrounding structures, such as catheterization, surgical interventions, or trauma from medical instruments. It results from scarring or tissue changes during healing.

Risk Factors

• Undergoing urological surgeries, repeated catheter use, or prior urethral trauma.
• Procedures involving the urethra, such as endoscopic surgery or instrumentation.

Symptoms

• Weak or interrupted urine stream.
• Difficulty initiating or completing urination.
• Increased frequency or urgency of urination.
• Pain during urination or ejaculation.
• Urinary tract infections.

Diagnosis

Diagnosis involves a physical examination, patient history, and imaging studies such as retrograde urethrogram or cystoscopy to visualize the urethra. Uroflowmetry may assess urine flow rates.

Treatment Options

• Urethral dilation or urethrotomy to widen the narrowed area.
• Open surgical reconstruction (urethroplasty) for complex cases.
• Catheterization or stenting to maintain patency during healing.

Prognosis and Follow-Up

With appropriate treatment, the prognosis is generally good, though strictures may recur. Regular follow-up may be necessary to monitor for recurrence or complications.

Complications

• Recurrent stricture formation.
• Urinary retention or incontinence.
• Chronic urinary tract infections.
• Impaired kidney function due to prolonged obstruction.

Lifestyle & Prevention

• Avoiding unnecessary urethral instrumentation when possible.
• Maintaining good hygiene to reduce infection risk.
• Following post-procedure care instructions to minimize scarring.

When to Seek Professional Help

Seek medical attention if experiencing persistent urinary symptoms, pain, or signs of infection after a procedure.

Tips for Medical Coders

Document the specific location (fossa navicularis) and postprocedural nature of the stricture. Ensure clinical notes support the diagnosis and any associated procedures or complications.
