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.
网膜包裹术通常在输尿管松解术后进行，以防止输尿管因输尿管周围粘连和纤维化复发而阻塞。我们报告了一例37岁的白人女性病例，她有两次剖宫产和因子宫内膜异位症行剖腹手术史。随后，她因右侧远端输尿管狭窄导致右侧胁腹疼痛，需要长期留置输尿管支架。诊断性腹腔镜检查显示输尿管受到外部压迫，为此进行了机器人辅助输尿管松解术。由于网膜不足，我们报告首次使用冷冻保存的生物再生脐带羊膜同种异体移植物进行输尿管包裹，以促进输尿管组织愈合，并作为粘连屏障防止纤维化复发。
