Incidence and risk factors for urinary retention after endoscopic hernia repair.
BACKGROUND
Postoperative urinary retention (PO-UR) frequently complicates the repair of inguinal hernias. The purpose of this study was to determine the incidence of and risk factors for developing PO-UR in patients undergoing endoscopic inguinal hernia repair.


METHODS
The incidence of PO-UR was determined by a retrospective review of a prospective patient database for all patients undergoing inguinal hernia repair by 1 surgeon from 2001 to 2003 at a tertiary referral center. A case-control study was used to identify risk factors for the development of PO-UR.


RESULTS
Thirty-four (22.2%) out of 153 patients undergoing endoscopic inguinal hernia repair developed PO-UR. The use of narcotic analgesia and the volume of intravenous postoperative fluid administered were significant risk factors (P < .05) for the development of PO-UR.


CONCLUSIONS
Postoperative urinary retention is common after totally extraperitoneal and transabdominal preperitoneal inguinal hernia repairs and is associated directly with increased narcotic and postoperative intravenous fluid administration.
