1289 Urinary Retention Following Outpatient Minimally Invasive Hysterectomy

Study Objective Identify risk factors associated with postoperative urinary retention in patients undergoing minimally invasive outpatient hysterectomy. Design Retrospective cohort study Setting Academic medical center Patients or Participants All patients undergoing outpatient minimally invasive hysterectomy between January, 2013 to July, 2018 were considered for inclusion. Interventions Outpatient laparoscopic, vaginal, or robotically-assisted-laparoscopic hysterectomy. Measurements and Main Results A total of 543 patients met inclusion criteria. Postoperative urinary retention occurred in 175 patients (cases) and 368 patients successfully passed their voiding trial in the postanesthesia care unit (controls), for a pass rate of 68%. Cases were older (mean age 54.5 years, SD=11.9 vs. 49 years SD=10.2, p Conclusion In patients undergoing minimally invasive outpatient hysterectomy, performing concomitant FPMRS procedures, having a longer operating time, and increased perioperative narcotic use is shown to increase the risk of postoperative urinary retention. The rate of urinary tract infection is higher in patients who experience postoperative urinary retention.
