To determine the proportion of patients discharged with a urinary catheter after a same-day benign gynecologic minimally invasive hysterectomy (MIH) according to active vs passive voiding protocols. The secondary objectives included assessing postanesthesia care unit (PACU) duration and postoperative urinary retention (POUR) rate ≤2 weeks of discharge. Design: Retrospective, observational cohort study. Setting: Large integrated healthcare system serving approximately 40% of the Northern California population. Patients: Patients aged 18 years or older undergoing same-day MIH without urogynecology procedures from 2015 to 2018 were categorized into active or passive voiding trial groups. Active voiding trials were defined as patients arriving in the PACU with a catheter, retrograde filling of the bladder with 300 mL saline then allowing for voiding ≥50% within 30 minutes. If the patients were unable to void this volume, they were discharged with a catheter to be removed within 24 hours. A passive voiding trial involved filling or not filling the bladder before PACU arrival without a catheter, then allowing for voiding or performing a straight catheterization if the patients were unable to void. Interventions: Retrospective cohort study. Measurements and Main Results: A total of 1644 (83.2%) patients underwent passive voiding trials, and 333 (16.8%) underwent active voiding trials. The proportion of patients discharged with a catheter was lower in the passive voiding group than in the active voiding group (5.4% vs 10.5%; p = .001). The passive group had a shorter mean PACU time than the active group (218 § 86 vs 240 § 93 minutes; p <.001). The crude POUR rates for the passive and active voiding groups were 1.8% and 3.0%, respectively (p = .16). Conclusion: Within an integrated healthcare system, patients who underwent passive voiding trials compared with those who underwent active voiding trials were discharged home from the PACU after a shorter duration. In addition, a larger proportion of the patients who underwent passive voiding trials were discharged home without a urinary catheter. There were no differences in the POUR rates. Our findings suggest that passive voiding trials can be safely used after a benign MIH to reduce hospital duration, optimize healthcare resources, and improve patient experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
