Abstract
Abstract: Urethral calculus is a late complication of urethroplasty for hypospadias when hair-bearing scrotal skin is included in the neourethra. From 1992 to 2002, we had one adolescent and four adult hypospadiac patients with urethral calculi. All patients had undergone staged repair for severe hypospadias at our institute or another hospital in their childhood. Open ureterolithotomy or endoscopic ureterolithotripsy was conducted except in one patient. Open ureterolithotomy was conducted successfully including retubularization with trimming of the diverticular area of the neourethra in two patients. Endoscopic ureterolithotripsy was conducted via Lithoclast in the other two patients. The calculi were struvite in the four patients.
