Impact of Urinary Catheterization on Postoperative Outcomes After Roux-En-Y Gastric Bypass Surgery in Propensity-Matched Cohorts

Background The impact of urinary catheter avoidance in bariatric enhanced recovery after surgery (ERAS) protocols is yet to be established. The purpose of the current study is to determine whether urinary catheter use in patients undergoing Roux-en-Y gastric bypass (RYGB) procedures has an effect on postoperative outcomes. Methods An institutional database was utilized to identify adult patients undergoing primary minimally invasive RYGB surgery. Outcomes included incidence of urinary tract infection (UTI) within 30 days postoperatively, 30-day readmission rates, proportion of patients discharged after postoperative day 1 (delayed discharge), length of stay (LOS), and operating room time. These were compared between propensity-matched groups with and without urinary catheter placement. Results There were no significant differences in postoperative UTI’s (2.2% for both cohorts, P = .593) or 30-day readmission rates for patients with and without urinary catheters (6.6% and 4.4%, respectively, P = .260). Mean LOS (1.7 vs. 1.5 days, P = .001) and the proportion of patients having a delayed discharge (47.3% vs. 33.7%, P = .001) was greater in patients with a catheter. Operating room time was longer in the urinary catheter group (221.8 vs. 207.9 minutes, P = .002). Discussion Avoidance of indwelling urinary catheters in RYGB surgical patients decreased delayed discharges and LOS without affecting readmission or reoperation rates. Therefore, we recommend that avoidance of urinary catheters in routine RYGB surgery be considered for inclusion into standardized ERAS protocols. Urinary catheters should continue to be utilized in select cases, however, as these were not shown to affect rate of UTIs.
