Abstract

OBJECTIVE:To determine whether backfilling the bladder postoperatively will reduce time to discharge in patients undergoing outpatient laparoscopic hysterectomy.METHODS:In a single-blind, randomized, controlled trial among women undergoing outpatient laparoscopic hysterectomy, patients were randomly assigned to a backfill-assisted void trial or a trial of spontaneous voiding. The primary outcome was time to discharge assessed by length of time spent in the postanesthesia care unit. Secondary outcomes included time to first spontaneous void, urinary retention rates, and postoperative complications within 8 weeks. We estimated that 152 patients (76/group) would provide greater than 80% power to identify a 30-minute difference in the primary outcome with a SD of 56 minutes and a two-sided α of 0.05.RESULTS:Between June 2017 to May 2018, 202 women were screened, 162 women were randomized, and results were analyzed for 153 women. Seventy-five patients (group A) who had a backfill-assisted voiding trial and 78 patients (group B) who had a spontaneous voiding trial were included in the analysis. The mean time to discharge was 273.4 minutes for group A vs 283.2 minutes for group B, which was not found to be significant (P=.45). The mean time to first spontaneous void was 181.1 minutes in group A vs 206.0 minutes in group B. There was a statistically significant reduction of 24.9 minutes in time to first spontaneous void with patients randomized to the backfill group (P=.04). Five of 75 patients (6.7%) in group A and 10 of 78 patients (12.8%) in group B developed urinary retention postoperatively and required recatheterization before discharge, which was also not significant (P=.20).CONCLUSION:Bladder filling before removing the Foley catheter is a simple procedure shown to reduce time to first spontaneous void, but not time to discharge in patients undergoing outpatient laparoscopic hysterectomy.CLINICAL TRIAL REGISTRATION:ClinicalTrials.gov, NCT03126162.
