CaseThe patient was a 3-year-old with hypospadias. Urethroplasty was performed as a two-stage procedure, but a severe urethral stricture occurred due to a postoperative infection and the patient was virtually in urinary retention. An emergency cystostomy was performed, and thereafter urethral reconstruction was performed. A large urethral diverticulum had formed in the scrotum. The inner wall of the diverticulum was found to be completely epithelialized and well vascularized. Therefore, it was elevated as a skin flap and a neourethra was reconstructed up to the glans region using the diverticular tissue.
OutcomePostoperative complications were not observed, and micturition was satisfactory.
ConclusionA urethral diverticulum is one of the often encountered complications of hypospadias surgery. However, there are only a few literature reports related to the treatment of urethral diverticulum. In addition, there are almost no reports on reconstructions using urethral diverticular tissue. In this report, we describe such a treatment experience.
