“…When comparing backfill-assisted VT and autofill VT, time to spontaneous void was shown to be shorter with a backfill-assisted VT as compared to autofill VT in one randomized trial; 21 otherwise proportion discharged with catheter, proportion of VT failure, retention after initial VT, time in PACU, time to discharge, duration of catheterization, patient burden and urinary tract infection (UTI) rate were similar. When comparing backfillassisted versus FoS assessment, time to discharge was shown to be shorter with FoS as compared to backfill-assisted VT in one study, 25 with equal outcomes reported for proportion discharged home with catheter, number of postoperative visits, proportion of VT failure, surgery for retention, retention after initial VT, duration of catheterization and UTI. None of the included studies reported outcomes related to number of postoperative calls and provider burden.…”
