The goal of this prospective, randomized trial is to determine the optimal duration of urinary catheterization in patients that receive elective, right-sided colectomy. The main objectives of this study are:
Enrolled participants will be randomized to one of two groups, immediate removal of urinary catheter at the conclusion of the operation or removal of urinary catheter on post operative day one.
Urinary catheterization is indicated for various operations conducted by colorectal surgeons. This process allows a tube to be inserted into the bladder to provide decompression while the patient is anesthetized. Prolonged urinary catheter placement is associated with urinary retention, urinary tract infections, and increased hospital length of stay. Clinical guidelines recommend urinary catheter discontinuation within 24 hours of operation but there is mixed evidence to support this recommendation. Further, there is a paucity of data that investigates optimal urinary catheter duration in specific colorectal surgery operations.
This prospective, randomized clinical trial aims to identify the optimal urinary catheter duration for patients undergoing elective, right-sided colectomy. Patients will be randomized into two groups: 1) urinary catheter discontinuation at the completion of surgery, or 2) urinary catheter discontinuation on post operative day 1. The primary objective is to compare rates of urinary retention between groups. The investigators hypothesize that patients with immediate urinary catheter discontinuation will have reduced rates of urinary retention and urinary tract infections compared to the group with urinary catheters maintained until post operative day 1.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Participants will undergo urinary catheter removal immediately after completion of surgery, in the operating room on post operative day 0.
Procedure: Immediate Urinary Catheter Removal
Participants will undergo urinary catheter removal on post operative day 1.
Procedure: Postoperative Day 1 Urinary Catheter Removal
Removal of the urinary catheter immediately after elective right hemicolectomy before leaving the operating room.
Also known as: POD0 catheter removal, Immediate Foley Removal
Removal of the intra-operatively placed Foley urinary catheter on the day after elective right-sided colectomy, post-operative day one.
Also known as: removal POD1 catheter removal, next-day Foley removal
Percentage of Participants With Post Operative Urinary Retention
Post operative urinary retention will be identified by inability to void within 8 hours after catheter removal, associated suprapubic fullness and/or tenderness, and a bladder scan volume greater than 300 mL; or by spontaneous voiding with urinary symptoms and a post-void residual volume greater than 300 mL. Symptoms include suprapubic pain or fullness, bladder pressure, incomplete emptying, or straining.
Time frame: From initial post operative urinary catheter removal through hospital discharge, assessed up to 90 days.
Percentage of Participants With Urinary Tract Infection
Urinary tract infection will be identified by clinical signs or symptoms such as suprapubic pain or tenderness, dysuria, hematuria, or urinary frequency, together with a urine culture showing more than 100,000 colony-forming units/mL of bacteria. Urinalysis and urine culture will be obtained only when infection is clinically suspected.
Time frame: From post operative day one through hospital discharge, assessed up to 90 days.
Postoperative Hospital Length of Stay
Number of inpatient hospital days from the day of surgery to the day of discharge.
Time frame: From post operative day one through hospital discharge, assessed up to 90 days.
Plan to share: No — Consent does not permit sharing; will revisit

Start is estimated for Nov 2026; primary completion for May 2028, 18 months later.
Of 136 non-industry interventional studies with no phase under Urinary Tract Infections, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 39. This study's planned 18 months is below that.
Counting every sponsor, half of 153 studies reached it within 22 months; a quarter within 8 and three quarters within 37.
