Surgical technique of robot-assisted laparoscopic ileal ureter replacement with extracorporeal ileal segment preparation. A Port placement. B Ureterectomy. C Measurement of the distance from the proximal ureteral transverse section to the bladder dome. D The ileal segment (necessary length acquired by the stent measurement) was isolated. E The mesentery of harvested bowel segment was incised parallel to the axis of the bowel approximately 3 cm on both sides. F For left-sided procedures, the ileal segment was brought into the retroperitoneal cavity through a mesenteric window in the sigmoid colon. G The pyeloileal anastomosis. H The ileovesical anastomosis
