Description of modified ileal conduit surgery for PL. a, b The left and right ureters were fully dissociated to the level of the lower pole of the kidney, and a ureteral stent was placed, respectively. c, d A 25 cm-long ileum was isolated and excised near 15 cm from the ileocecal part to make the ileal conduit and the continuity of the original bowel was restored. e, f At the level of the lower pole of the left kidney, the incised left ureteral orifice was anastomosed end-to-end with the proximal ileal conduit. g A small hole was cut near 10 cm from the proximal end of the ileal conduit. h The incised right ureteral orifice was anastomosed with the ileal conduit at the level of the lower pole of the right kidney. i The distal end of the ileal conduit and the ureteral stent were pulled out of the abdominal wall together, and the distal end was sutured into a papillary shape and fixed with the abdominal wall.
