Purpose
Acute urinary retention (AUR) is a common postoperative complication in colorectal surgery. In pelvic colorectal operations, the optimal duration for postoperative urinary catheter use is controversial. This systematic review and meta-analysis aims to compare early (POD 1), intermediate (POD 3), and late (POD 5) urinary catheter removal.
Methods
Medline, EMBASE, CENTRAL, and PubMed databases were searched. Articles were eligible for inclusion if they compared patients with urinary catheter removal on POD 1 or earlier to patients with urinary catheter removal on POD 2 or later in major pelvic colorectal surgeries. The primary outcome was rate of postoperative AUR. The secondary outcome was rates of postoperative urinary tract infection (UTI).
Results
From 691 relevant citations, five studies with 928 patients were included. Comparison of urinary catheter removal on POD 1 versus POD 3 demonstrated no significant difference in rate of urinary retention (RR 1.36, 95%CI 0.83–2.21, P = 0.22); however, compared to POD 5, rates of AUR were significantly higher (RR 2.58, 95%CI 1.51–4.40, P = 0.0005). Rates of UTI were not significantly different between POD 1 and POD 3 urinary catheter removal (RR 0.40, 95%CI 0.05–3.71, P = 0.45), but removal on POD 5 significantly increased risk of UTI compared to POD 1 (RR 0.50, 95%CI 0.31–0.81, P = 0.005).
Conclusion
Risk of AUR can be minimized with late postoperative urinary catheter removal compared to early removal, but at the cost of increased risk of UTI. Patient-specific factors should be taken into consideration when deciding upon optimal duration of postoperative urinary catheterization.
