Early Post-operative Removal of Urethral Catheter in Patients Undergoing Colorectal Surgery With Epidural Analgesia

All participants are to have a urethral catheter placed following successful placement of an epidural catheter for analgesia prior to undergoing colorectal resection. Following urethral catheter placement participants will be randomly assigned to either the experimental arm or the control arm. Participants assigned to the experimental arm will have their urethral catheters removed at 48 hours following surgery. Participants assigned to the control group will have their urethral catheters removed within 12 hours of withdrawal of the epidural infusion, as is standard practice in our institution.
