  • Title: Indwelling catheter can increase postoperative urinary tract infection and may not be required in total joint arthroplasty: a meta-analysis of randomized controlled trial.
    Author: Ma Y, Lu X.
    Journal: BMC Musculoskelet Disord; 2019 Jan 05; 20(1):11. PubMed ID: 30611266.
    Abstract:
    BACKGROUND: The purpose of this study was to investigate whether patients undergoing total joint arthroplasty (TJA) require catheterization. METHODS: PubMed, EMBASE, Web of Science, Cochrane Library and China National Knowledge Infrastructure were systematically searched. All randomized controlled trials (RCTs) receiving either a urinary catheterization or no urinary catheterization were included. Meta-analysis results were assessed by RevMan 5.3 software. RESULTS: Seven independent RCTs were included, with a total sample size of 1533 patients, including 750 patients in the indwelling catheter group and 783 patients in the none-indwelling catheter group. Our pooled data analysis indicated that patients in the indwelling catheter group had a higher risk of urinary tract infection than patients in the none-indwelling catheter group (RR, 3.21; P = 0.0003). However, the meta-analysis indicated that there was no significant difference between the two groups in terms of urinary retention (RR, 0.67; P = 0.13), duration of the surgery (MD, - 0.37; P = 0.55), and length of hospital stay (MD, 0.15; P = 0.38). CONCLUSION: Based on the current evidence, this meta-analysis showed that urinary catheterization during TJA can increase the postoperative urinary tract infection, and it may not routinely be required for the patients undergoing TJA. LEVEL OF EVIDENCE: Level I, therapeutic study.
