Summary

This trial will test if tamsulosin can reduce post-op urinary retention in men after rectal surgery. Secondary outcomes are length of stay, number of catheterizations, re-insertions, & duration of catheter.

Who is the study for?
This trial is for male patients aged 18 or older who are scheduled for rectal resection. It's not open to those with urinary tract trauma, epidural anesthesia during surgery, revisional surgeries, past urinary tract surgeries, current alpha-blocker medication use, indwelling catheters post-surgery over 24 hours, or intolerance to alpha-blockers.
What is being tested?
The study tests if Tamsulosin can prevent urinary retention after rectum resection in men. It's a phase III trial where participants are randomly given either Tamsulosin or a placebo without knowing which one they receive (double-blind). Hospital stay length and number of catheterizations will also be compared.
What are the potential side effects?
Tamsulosin may cause dizziness, headache, sleepiness, nausea, low blood pressure upon standing up (orthostatic hypotension), and ejaculation problems. These side effects aren't guaranteed but are possible.

Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: Group receiving TamsulosinActive Control1 Intervention
Patients randomized to the intervention group will receive 0.4 mg tamsulosin capsules, administered orally, once a day for 5 days before surgery, the morning of surgery and the day after surgery. The steady-state plasma concentration of tamsulosin is reached after 4 to 5 consecutive doses, which justify the administration duration of 5 days preoperatively. The total duration of administration of tamsulosin was established at 7 days since the study of Patel et al. showed a significant reduction in POUR after 7 days of administration.
Group II: Group receiving PlaceboPlacebo Group1 Intervention
Patients assigned to the placebo group will receive glucose capsules according to the same protocol. The glucose capsules will be manufactured by the pharmacy of the CHU de Quebec.
