The results of this study suggest that the use of an indwelling urinary catheter following total knee arthroplasty may increase the risk of urinary tract infection and lengthen the time to first urination, without any significant reduction in urinary retention. This study was limited by the variation in definitions for urinary retention, limited follow up time in the included studies, and small number of RCTs included in the meta-analysis. Future high quality trials are needed to confirm the conclusions of the study.
Study Summary
Six randomized controlled trials containing a total of 1334 total knee arthroplasty patients were included in this meta-analysis comparing post-operative indwelling urinary catheterization (n=687) to no catheterization (n=647). Pooled outcomes of interest included urinary retention, urinary tract infection, length of hospital stay, duration of surgery, and time to first urination. Results of the meta-analysis demonstrated significantly greater risk of urinary tract infection (p=0.009) and longer time to first urination (p=0.004) in patients with indwelling urinary catheters than those without indwelling urinary catheters. No significant differences in pooled risk of urinary retention (p=0.52), length of stay (p=038) or duration of surgery (p=0.55) were observed between the two groups.
