Summary

This study looks at whether removing a urinary catheter one day after colorectal surgery is as safe as the standard three days. About 176 adults having certain pelvic surgeries will be randomly assigned to early or standard removal. The goal is to see if shorter use lowers infection rates without increasing the chance of urinary retention.

Inclusion Criteria: * Elective procedures involving total mesorectal excision, including low anterior resection and abdominoperineal resection for rectal cancer as well as proctectomy for inflammatory bowel disease. * All approaches (open, laparoscopic and robotic) will be included, as the approaches not differ in the total mesorectal excision technique. * Patients who received neoadjuvant chemotherapy and/or radiation treatments will be included. * Age ≥ 18 years. * American Society of Anesthesiologists (ASA) class I-III. * Ability to understand and the willingness to sign a written informed consent.
