Abstract Purpose To compare the efficacy and time-to-discharge of two methods of trial of void (TOV): bladder infusion versus standard catheter removal. Methods Electronic searches for randomized controlled trials (RCTs) comparing bladder infusion versus standard catheter removal were performed using multiple electronic databases from dates of inception to June 2020. Participants underwent TOV after acute urinary retention or postoperatively after intraoperative indwelling catheter (IDC) placement. Quality assessment and meta-analyses were performed, with odds ratio and mean time difference used as the outcome measures. Results Eight studies, comprising 977 patients, were included in the final analysis. Pooled meta-analysis demonstrated that successful TOV was significantly higher in the bladder infusion group compared to standard TOV (OR 2.41, 95% CI 1.53–3.8, p = 0.0005), without significant heterogeneity (I2=19%). The bladder infusion group had a significantly shorter time-to-decision in comparison to standard TOV (weighted mean difference (WMD)—148.96 min, 95% CI − 242.29, − 55.63, p = 0.002) and shorter time-to-discharge (WMD − 89.68 min, 95% CI − 160.55, − 18.88, p = 0.01). There was no significant difference in complication rates between the two groups. Conclusion The bladder infusion technique of TOV may be associated with a significantly increased likelihood of successful TOV and reduced time to discharge compared to standard TOV practices.

Indwelling catheter (IDC) insertion is a common approach for a number of circumstances including acute urinary retention and as part of postoperative protocols. Acute urinary retention affects 5–70% of patients postoperatively [1–3], with a high
