Summary
There is no general agreement about the optimal duration of postoperative urinary drainage,
with relevant literature reporting durations ranging from 1 to 10 days. The available
research supporting the routine use of prolonged catheterization is limited and studies
investigating early removal following infraperitoneal colorectal surgery have largely been
underpowered to form valid practice conclusions. The aim of the investigators study is to
determine whether a postoperative colorectal patient can safely have an indwelling catheter
removed on postoperative day one (24 hours following surgery) with the addition of a study
medication (prazosin), without a statistically significant difference in the incidence of
urinary retention compared to the standard, accepted approach of delayed removal (72 hours
postoperatively). Patients undergoing laparoscopic and open pelvic colorectal surgery below
the peritoneal reflection for both benign and malignant conditions will be randomized into
two groups: group one will have the catheter removed on postoperative day 3 (72 hours
postoperatively) Group 2 will have a dose of the alpha-blocker prazosin given 6 hours prior
to catheter removal and will have the urinary catheter removed on postoperative day 1 (24
hours postoperatively).
