Successful management of ureteral injury after gender-affirming laparoscopic hysterectomy: A case report.

Introduction And Importance: A two-step process involving ureteral stenting and surgical repair is generally recommended to manage a delayed diagnosis of postoperative ureteral injury; however, retrograde stenting is often difficult.

Case Presentation: A 35-year-old female-to-male transgender person who underwent laparoscopic gender-affirming total hysterectomy with bilateral salpingo-oophorectomy developed right ureteral injury at 2 months postoperatively. Initially, the stenting guidewire could not pass through the stenotic tract and was diverted into the abdominal cavity. Using a 0.014-in. microguidewire and a 2-Fr microcatheter, both of which are designed for angiography, the ureteral stent was ultimately placed. The patient underwent surgical repair using the Boari flap technique. The double J catheter was removed at 1 month postoperatively, and postoperative retrograde pyelography revealed no urinary leakage or ureteral stricture.

Clinical Discussion: Immediate primary repair is desirable for intraoperative ureteral injuries. However, up to 70 % of ureteral injuries are diagnosed during the postoperative period. For a delayed diagnosis of ureteral injury, urinary diversion with ureteral stent, nephrostomy, or both, followed by delayed repair, is recommended to avoid the inflammatory phase. In this patient, ureteral stenting was difficult on the first attempt. Thin microguidewires designed for angiography could be useful in such difficult situation.

Conclusion: A ureteral injury at the mid-ureter diagnosed at 2 months postoperatively was successfully managed using a two-step process involving ureteral stenting and surgical repair. A microguidewire and a microcatheter are useful for successful stenting in patients with late-diagnosed, severe ureteral strictures.
