Bioregenerative Umbilical Cord Amniotic Membrane Allograft Ureteral Wrap During Robot-Assisted Ureterolysis

J Endourol Case Rep. 2020 Dec 29;6(4):431-434. doi: 10.1089/cren.2020.0185. eCollection 2020.

Abstract

Omental wrap is commonly performed after ureterolysis to prevent ureteral obstruction from recurrence of periureteral adhesions and fibrosis. We present the case of a 37-year-old Caucasian woman with a history of two cesarean sections and laparotomy for the treatment of endometriosis. She subsequently developed right flank pain caused by a right distal ureteral stricture requiring a chronic indwelling ureteral stent. Diagnostic laparoscopy revealed extrinsic compression of the ureter for which robot-assisted ureterolysis was performed. Because of inadequate omentum, we report the initial use of a cryopreserved bioregenerative umbilical cord amniotic membrane allograft to perform a ureteral wrap to promote ureteral tissue healing and serve as an adhesion barrier to prevent recurrence of the fibrosis.
