Insights
Congenital urethral stricture in boys, a rare condition causing enuresis, can be effectively treated. Surgical incision of bulbar narrowing resolved daytime wetting and improved nighttime control in pediatric patients.
Area of Science:
- Pediatric Urology
- Medical Case Reports
Background:
- Congenital urethral stricture is a condition affecting young boys.
- It can lead to significant voiding dysfunction, including enuresis.
Observation:
- Three boys (ages 5-8) presented with persistent day and night enuresis.
- Voiding cystography identified bulbar narrowing (Cobb's Collar) and vesicoureteral reflux (VUR) in two cases.
Findings:
- Endoscopic examination revealed ring-form stenosis distal to the urethral sphincter.
- Infantile urethrotomy successfully incised the stenosis, resolving daytime enuresis and improving nighttime control.
- Vesicoureteral reflux resolved in two ureters and improved in one post-procedure.
Implications:
- Congenital urethral stenosis is a treatable cause of enuresis in boys.
- Early diagnosis and endoscopic management offer significant functional improvement.
- This condition warrants greater recognition in pediatric urology.
Abstract:
We report three cases of congenital urethral stricture in boys. They were 8, 7 and 5 years old. They complained of enuresis both day and night. Voiding cystography revealed bulbar narrowing (Cobb's Collar) in all cases, and vesico-ureteral reflux (VUR) occurred in two cases (three ureters). Endoscopically this lesion showed ring-form stenosis just distal to the urethral sphincter, and incised by using an infantile urethrotome. After the operation, VUR resolved in two ureters and improved in one. In all cases, daytime enuresis resolved dramatically, and night enuresis became controllable. Congenital urethral stenosis in boys is an important clinical entity in pediatric urology, and is not such a rare disease.
