BACKGROUND: To report short-term clinical outcomes of endoscopic correction of congenital urethral stricture in 10 boys who suffer from enuresis resistant to conservative therapy. METHODS: Fifteen boys ranging between 5 and 15 years old consulted our clinics for nocturnal and diurnal enuresis which had not been improved by medication and behavioral therapy. Among them, voiding cystography revealed bulbar narrowing (Cobb's Collar) in 10 cases and vesico-ureteral reflux was found in four cases (seven ureters). Endoscopically, this lesion was recognized as a ring-form stenosis just distal to the urethral sphincter. It was incised with infantile urethrotome. RESULTS: Vesico-ureteral reflux was resolved in four ureters and improved in one. In all cases, daytime enuresis resolved dramatically and night enuresis became controllable. CONCLUSIONS: Boys who suffer from diurnal enuresis should immediately be explored for the existence of congenital urethral stenosis. Early resolution may bring about better urinary behavior.
