Clinical experience and video description of minimally invasive surgery for benign prostatic obstruction using the Schelin Catheter®.

Although designed for in-office use, water vapor thermal therapy (Rezum™) remains a painful procedure, and oral±intravenous sedation is often required. Schelin Catheter® (ProstaLund AB, Lund, Sweden) is an innovative bladder catheter that delivers local anesthesia to the prostate in a sterile transurethral way. We aimed to evaluate the safety and feasibility of Rezum™ for male lower urinary tract symptoms due to benign prostatic obstruction (LUTS/BPO) with local anesthesia delivered with Schelin® catheter, and to report its first step-by-step video description. A total of 15 patients were enrolled, and 14 analyzed. Median pain numeric rating scale at catheter insertion, anesthetic injection, Rezum™ insertion, Rezum™ treatment, and at 2-h postoperatively were 3 (2-5), 3 (2-5), 1 (0-3), 3.5 (2-6), and 0 (0), respectively. In 1 patient local anesthesia protocol failed and intravenous sedation was used. All Rezum™ therapies were performed successfully. Local anesthesia with Schelin® catheter opens up new possibilities for ultra-minimally invasive surgery for LUTS/BPO.
