Immediate urinary catheter removal after colorectal surgery with the enhanced recovery after surgery protocol.

Abstract

The Enhanced Recovery After Surgery protocol for colorectal surgery recommends early urinary catheter (UC) removal after surgery. However, the optimal timing remains controversial. We aimed to evaluate the safety of immediate UC removal and risk factors of postoperative urinary retention (POUR) after colorectal cancer surgery. From November 2019 and April 2022, patients who underwent elective colorectal cancer surgery at Seoul St. Mary's hospital were collected retrospectively. A UC was inserted in the operating room after general anesthesia and removed in the operating room immediately after surgery. The primary outcome was the occurrence of POUR following immediate UC removal after surgery, and the secondary outcomes were the identification of POUR-related risk factors and postoperative complications. Among 737 patients, 81 (10%) had POUR immediately after UC removal. No patient had urinary tract infection. The incidence of POUR was significantly higher in male and in those with a history of urinary disease. However, there were no significant differences in tumor location, surgical procedure, or approach. The mean operative time was significantly longer in the POUR group. Postoperative morbidity and mortality rates did not differ significantly between two groups. Multivariate analysis showed that risk factors for POUR were male, a history of urinary disease, and intrathecal morphine injection. Immediate removal of UC immediately after colorectal surgery is safe and feasible in the trend of ERAS. Male, ahistory of benign prostatic hyperplasia, and intrathecal morphine injection were risk factors for POUR.
