Urinary retention in early urinary catheter removal after colorectal surgery.

ABSTRACT

BACKGROUND: High urinary infection (UTI) rate (12%) for our rectal surgery prompted practice change to early catheter removal (postoperative day 2) and prophylactic tamsulosin. Here we report urinary retention (UR) and UTI after this change. METHODS: Retrospective cohort study in male patients 50+ years undergoing elective colorectal surgery from July 2015 to July 2017. Multivariate regression was used to determine risk factors for urinary retention. RESULTS: 157 patients, 57 without and 100 with tamsulosin had UR 11.46% and UTI 5.13%. Of all potential risk factors, ileus (OR 5.50, 95% CI 1.86-16.24) was an independent risk factor for urinary retention. CONCLUSIONS: Urinary retention of 11% after colorectal resection is within literature range and associated with post-operative ileus. Tamsulosin did not affect UR in our small study sample. Early catheter removal was associated with decreased UTI rate.
