Incidence of Acute Urine Retention: Randomized Clinical Trial Comparing Early, Mid or Late Urinary Catheter Removal in Patients With Rectal Resection

DESIGN: Randomized, open-label and parallel clinical trial, assigned to early, mid, or late withdrawal of urinary catheter with a 1: 1: 1 allocation ratio. POPULATION: Patients undergoing anterior rectal resection, low rectal resection, or abdominoperineal amputation for any reason. OBJECTIVES: The main objective is to compare the incidence of acute urine retention after removal of the urinary catheter in the postoperative period of rectal resection. Secondary objectives are: 1. Incidence of urinary tract infection after urinary catheter removal. 2. Incidence of specific postoperative complications (Surgical wound infection, Respiratory infection, Anastomotic dehiscence, ileus). 3. Incidence of postoperative complications assessed according to the Comprehensive Complication Index (CCI) scale. DESCRIPTION OF THE INTERVENTION: In all patients, a Rectal Resection (anterior rectal resection, posterior pelvic exenteration or abdominoperineal amputation) will be performed. In group 1A, the urinary catheter will be removed on the 1st postoperative day. In group 1B patients, the urinary catheter will be removed on the 3rd postoperative day. In group 1C patients, the urinary catheter will be removed on the 5th postoperative day. All patients will have a urine culture taken at the time of withdrawal.
