RCT Foley Catheter Study for Elective TJA
United States388 participantsStarted 2020-11-16
Plain-language summary
Urinary retention is a known complication following surgical procedures, with a theoretical increased risk in patients receiving neuraxial anesthesia due to a decreased ability to sense bladder distension. Urinary retention is associated with adverse events including bladder atony, increased post void residuals, and postoperative urinary tract infection. Treatment of urinary retention involves intermittent or indwelling urinary catheter placement, both of which are associated with an increased prevalence of postoperative urinary tract infection.
There currently is no consensus whether the use of a urinary catheter in elective joint arthroplasty with neuraxial anesthesia decreases the risk of urinary retention. The prevalence of retention reported in the literature varies widely with reports anywhere from 0% to 75% in patients with early removal of a catheter or after procedures performed without a catheter.
The goal of this study is to determine whether the routine use of an indwelling urinary catheter decreases the rate of postoperative urinary retention in patients undergoing elective joint arthroplasty.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Any patient \>18 years of age scheduled for an inpatient primary hip or knee replacement
Exclusion Criteria:
* Patients with a known history of prostate, urological or kidney surgery
* Patients where close monitoring of urine output are necessary during the perioperative period (renal disease, renal failure, chronic indwelling urinary catheter)
* Patients with a history of urinary incontinence
* Patients undergoing a revision total knee or total hip arthroplasty
* Patients requiring indwelling continuous epidural anesthesia
* Patients with a preexisting urinary tract infection, as diagnosed on preoperative screening.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
