Abstract
Purpose: We described laparoscopic nonrefluxing ureteral reimplantation with a psoas hitch using a submucosal tunneling technique combined with cystoscopy. Patients and Methods: We performed this operation on two female patients. The first patient had a right lower-ureteral stricture after a laparoscopy-assisted vaginal hysterectomy, and the second patient had a left distal-ureteral stricture after a left laparoscopic oophorectomy, which was performed for endometriosis. We performed laparoscopic intravesical ureteral reimplantations with a psoas hitch using submucosal tunneling after a submucosal injection of normal saline was provided under cystoscopy. Results: The operative times were 325 and 280 minutes, respectively. The estimated blood loss was 300 mL in the first case and 120 mL in the second. The hospital stays were 5 and 3 days, respectively. There were no postoperative complications. Follow-up voiding cystourethrography and intravenous urography demonstrated normal compliance and function of the kidneys and ureters with no vesicoureteral reflux. Conclusions: Laparoscopic intravesical nonrefluxing ureteroneocystostomy with a psoas hitch is a safe and feasible procedure. Cystoscopic submucosal injection of normal saline during submucosal tunneling is beneficial.
