Postoperative urinary retention after laparoscopic total extraperitoneal inguinal hernia repair

Abstract

BackgroundPostoperative urinary retention (POUR) after laparoscopic inguinal hernia repair has an incidence of 2%-30%. POUR can lead to increased length of stay, decreased patient satisfaction, and increased health-care costs. The objective of this study was to determine the patient risk factors at our institution contributing to POUR after laparoscopic total extraperitoneal (TEP) inguinal hernia repair. MethodsA retrospective chart review of patients who underwent a laparoscopic TEP inguinal hernia repair at our institution from 2009 to 2016. POUR is defined as the inability to urinate requiring urinary straight or indwelling catheterization in the postoperative period. Univariate analyses were performed on perioperative variables and their correlation with POUR. ResultsIn total, 578 laparoscopic TEP inguinal hernia repair patients were included in the study: 277 (48%) indirect, 144 (25%) direct, 6 (1%) femoral, and 151 (26%) combination of direct, indirect, and/or femoral hernias. Of these, 292 (51%) were bilateral, and 286 (49%) were unilateral. Overall, 64 (11.1%) of the 578 patients developed POUR. POUR was significantly associated with benign prostatic hyperplasia, age 60 y or older, urinary tract infection within 30 d, and decreased body mass index. ConclusionsPatients aged greater than 60 y, with benign prostatic hyperplasia, and a decreased body mass index (≤25.8 kg/m2) were more likely to develop POUR after laparoscopic TEP inguinal hernia repair. In addition, these patients were more likely to develop a urinary tract infection within 30 d. Future quality initiatives can be explored to minimize the incidence of POUR in high-risk patient populations.
