One case report of laparoscopic biological patch repair for the ureterosciatic hernia and literature review.

Ureterosciatic hernia is a very rare disease worldwide. We report a successful case of laparoscopic biological repair of large ureteral hernia. Preoperative CT examination showed ureterosciatic hernia with incarceration and proximal ureteral dilatation. Laparoscopic ureteral incarceration release, ureteral stent placement and biological patch repair of sciatic foramen hernia were performed. Under the observation of laparoscope, the stent was placed through urethra with cystoscope to restore the course of ureter. A biological patch was placed behind the ureter to cover the closed hernia ring. We have been followed up for 2 months after operation. According to the reexamination, the effect is obvious. Laparoscopic biological patch repair for ureteral sciatic foramen hernia has the advantages of less trauma, convenient operation and ideal prognosis in theory.
