Ureteral Reimplantation, Psoas Hitch, and Boari Flap.

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. 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. Robotic ureteral reimplantation with psoas hitch and Boari flap are demonstrated in a reproducible manner. Additional topics covered include the delineation of diseased ureter healthy ureter, the applications of indocyanine green, and the use of interoperative ureteral stents. 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.
