Ureteral Reimplantation, Psoas Hitch, and Boari Flap

摘要

Introduction: Ureteral reimplantation is indicated for patients with congenital distal ureteral strictures, for iatrogenic intraoperative distal ureteral injuries, and for those who require distal ureterectomy for transitional cell carcinoma. Methods: Using the da Vinci system from Intuitive, we demonstrate distal ureterectomy with reimplantation. Both a refluxing extravesical reimplant and nonrefluxing extravesical reimplant are shown. We also demonstrate modifications, including psoas hitch and Boari flap. Results: Robotic ureteral reimplantation with psoas hitch and Boari flap are demonstrated in a reproducible manner. Additional topics covered include the delineation of diseased ureter vs healthy ureter, the applications of indocyanine green, and the use of interoperative ureteral stents. Conclusions: Robotic ureteral reimplantation is safe and feasible when performed with proper technique. Ureteroscopy and near-infrared fluorescence technology facilitate improved detection of diseased ureteral segments. Key points include the maintenance of principles of open surgery such as a tension-free, watertight, and stented anastomosis.
