A Systematic Review of the Optilume® Drug-Coated Balloon in the Management of LUTS Secondary to BPH and Urethral Stricture

Le résumé fourni par la source

Background and Objective: Benign prostatic hyperplasia (BPH) and urethral stricture (US) are common causes of lower urinary tract symptoms in ageing men, often requiring repeated interventions. Conventional treatments of US, such as urethrotomy and mechanical dilation, have high recurrence rates. The Optilume drug-coated balloon catheter system, which combines mechanical dilation with paclitaxel delivery, has emerged as a minimally invasive alternative. This systematic review assesses its efficacy and safety in the management of BPH and US. Methods: A systematic search of PubMed was conducted for studies published between August 2020 and October 2023. Eligible studies included randomised controlled trials (RCTs), cohort studies, and case reports evaluating Optilume’s therapeutic effects. Key outcomes analysed included symptom relief, urinary flow improvement, recurrence rates, and adverse events. Results: Seven studies met the inclusion criteria, including five on US and two on BPH. The ROBUST trial series demonstrated sustained improvements in urinary flow rates and symptom scores in US patients over follow-up periods of up to four years. The EVEREST-1 and PINNACLE trials reported significant symptom relief and preserved sexual function in BPH patients, with a favourable safety profile and minimal complications. Conclusions: Optilume appears to be a promising alternative to conventional endoscopic treatments for US and BPH, offering durable symptom relief with a low complication rate. Further long-term studies are required to confirm its efficacy and cost-effectiveness in routine clinical practice.
