During radical cystectomy, the patient’s bladder is first completely removed, the lymph nodes near the bladder and the iliac vessels and paracervical lymph nodes of the closed nerve are cleared bilaterally, and then urinary flow is rerouted. In case of ureteral skin fistula, a stent tube needs to be placed in the ureter to prevent postoperative ureteral stricture. If the patient has a storage bladder, a section of bowel is amputated to implant the ureter on the storage bladder, which opens in the abdomen. If the patient has an in situ bladder, a section of bowel is cut and placed in the anatomical position of the patient’s bladder.
