Abstract
BACKGROUND: Postoperative urinary retention (POUR) is a common complication after inguinal hernia repair that may result in catheter-related infections or injuries, longer hospital stays, and thus, higher overall costs. Our aim was to assess the incidence of POUR after endoscopic total extraperitoneal (TEP) inguinal hernia repair and identify its risk factors. METHODS: We retrospectively analyzed all data that were included in a prospective Hernia Database for patients undergoing a TEP inguinal hernia repair at our institution between July 2012 and May 2018. POUR was defined as the inability to urinate spontaneously after surgery, thus requiring a bladder catheter. RESULTS: Data from 1570 patients were included. Sixty-five patients developed POUR, which was an incidence of 4.1%. In the univariate analysis, patients over 50 years of age (1.6% vs. 5.5%), patients with higher American Society of Anesthesiologists (ASA) score (ASA-1 2.7% vs. ASA-3 12.5%), previous prostate surgery (3.9% vs. 10.9%), unilateral operation (1.9% vs. 6.0%), and intraoperative drain placement (2.1% vs. 4.9%) developed POUR more often than younger patients. After multivariate adjustment, advanced age and unilateral surgery remained risk factors for POUR. CONCLUSION: Advanced age and unilateral inguinal hernia repair, possibly due to a lack of catheterization, were risk factors for POUR. Due to increasing outpatient inguinal hernia repairs worldwide, it is imperative to identify patients who are at risk of POUR to apply prophylactic measures and reduce readmission, and thus, reduce health-care costs.
