Comparing Clean Intermittent Self-catheterization and Indwelling Catheterization for the Management of Urinary Retention Before BPH Surgery.

The CATHETERS trial is a multicenter, randomized, open-label superiority study comparing two methods of managing urinary retention before surgery for benign prostatic hyperplasia (BPH): clean intermittent self-catheterization (ICSC) versus indwelling catheter (IDC). The primary objective is to determine whether ICSC reduces the occurrence of infectious complications (urinary bacterial colonization requiring antibiotic therapy, urinary tract infection, or urosepsis) compared to IDC in men awaiting BPH surgery. A total of 106 patients will be enrolled across multiple centers in France, with follow-up extending to three months after surgery.
