Monitoring urination after knee surgery without ultrasound
Urinary Retention After Arthroplasty - UREA Trial
This study is testing if monitoring how patients feel about urination after knee surgery is as safe as using ultrasound to check for problems.

What this trial studies
This study investigates the safety of monitoring spontaneous urination in patients after knee arthroplasty using symptoms alone, rather than ultrasound monitoring. Adult patients undergoing elective total knee arthroplasty will be randomly assigned to either a symptom-based monitoring group or an ultrasound monitoring group. The symptom-based group will be catheterized only if they report symptoms of urinary retention or have not voided within 10 hours post-anesthesia. The primary outcome will be assessed by changes in the International Prostate Symptom Score (IPSS) at three months post-surgery.
Who should consider this trial
Good fit: Ideal candidates are adults scheduled for elective total knee arthroplasty.
Not a fit: Patients with a history of urologic cancer surgery, fractures as an indication for surgery, or those requiring general anesthesia may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could reduce the need for catheterization and associated complications, improving patient outcomes after knee arthroplasty.
How similar studies have performed: While there is limited evidence on this specific approach, similar studies have explored symptom-based monitoring in other contexts, suggesting potential for success.
