Laparoscopic Repair of Ureteral Diverticulum Caused by Ureterosciatic Hernia.

Ureterosciatic hernia and ureteral diverticulum are rare conditions. Only a few cases with surgical management for these conditions have been reported. We report a case of ureteral diverticulum due to ureterosciatic hernia in an 85-year-old woman admitted for septic shock. Computed tomography and retrograde ureterography revealed obstructive ureterosciatic hernia. During intraoperative laparoscopic mesh repair for the hernia after urosepsis treatment, we noted ureteral diverticulum that was also detected endoscopically at the herniated ureter wall. Suture plication was performed to prevent stricture and hernia mesh infection. To our knowledge, this is the first report on ureteral diverticulum due to ureterosciatic hernia.
