About this trial

This randomized controlled trial investigates the effectiveness and safety of the Optilume® drug-coated balloon (DCB) compared to standard direct visual internal urethrotomy (DVIU) in the treatment of bulbar urethral strictures. The primary objective is to assess freedom from repeat intervention at 12 months. Secondary objectives include evaluating urethral patency, urinary symptoms, and sexual function through objective measures (Qmax, PVR, cystoscopy) and patient-reported outcomes (USS-PROM, IPSS, IIEF-5). The study will recruit 140 participants across multiple sites, with follow-ups conducted at 6 and 12 months. This trial seeks to provide evidence for Optilume DCB as a safe and effective alternative to standard treatment.
