Endourology & Stone Disease(비디오) (V-007) Boari flap을 이용한 로봇보조복강경하 요관방광문합술 인제대학교 해운대백병원 김정호, 박명찬, 정재승, 박상현, 오철규 Ureteral reconstruction is performed for a variety of disease that includes ureteral stricture, iatrogenic ureteral injury and ureteral malignancy. Treatment options include ureteroureterostomy, ureteroneocystostomy (with or without a psoas hitch or Boari flap), ileal ureter, and transureteroureterostomy. Depending on the etiology and nature of the ureteral lesion, the decision as to which repair to perform is often made in the operating room when tension can be assessed. Over the past decade, there has been an increasing shift towards robot-assisted laparoscopic surgery with multiple institutions reporting their outcomes. Robot-assisted surgery offers intraoperative advantages, including three-dimensional visualization with magnification and wristed movements with additional degrees of freedom. We present the case of a 33-year-old women with a persistent ureteral stricture underwent robot-assisted surgery for definitive management. To optimize the repair with tension-free anastomosis, creation of a Boari-flap was chosen pre-operatively. The surgery was completed without complication. The patient remains asymptomatic at 6 months with CT scan demonstrating without hydronephrosis. The robot-asssted laparoscopic Boari flap ureteral reimplantation is feasible and safe for patients with long-segment ureteral stricture. keywords : ureteral stricture, Boari flap, Robot
