Case: The 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.
Outcome: Postoperative complications were not observed, and micturition was satisfactory.
Conclusion: A 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.
