The UREA trial is a randomized clinical trial assessing postoperative urinary retention (POUR) monitoring methods in 170 patients undergoing total knee arthroplasty (TKA). It compares symptom-based monitoring to ultrasound-based monitoring, aiming to determine if symptoms alone can safely guide catheterization decisions. The primary outcome is the difference in International Prostate Symptom Score (IPSS) at 3 months.
Key findings
- The trial includes 170 patients randomized in a 1:1 ratio to either monitoring group.
- Primary outcome measures the difference in IPSS between groups at 3 months.
- Secondary outcomes include urinary complications and health-related quality of life at 3 and 12 months.
Why it matters
Understanding the effectiveness of symptom-based monitoring for POUR could lead to reduced catheterizations, minimizing patient discomfort and the risk of urinary tract infections, ultimately improving postoperative care efficiency.
