<b><i>Introduction:</i></b> The Butterfly Prostatic Retraction device is a novel transurethral implant designed to dilate the prostatic urethra and treat lower urinary tract symptoms. We assessed its safety, efficacy and impact on urinary flow, ejaculation, and quality of life. <b><i>Materials and Methods:</i></b> We included 64 men, treated for benign prostate hyperplasia for at least 1 year. All patients had Qmax≤ 13 mL/s and IPSS &#x3e;12. Insertion of the device was performed via cystoscopy. Follow-up visits were performed at 2 weeks, 1, 3, 6, and 12 months and included uroflowmetry, IPSS, QoL, and sexual function questionnaires. Cystoscopy was performed on 3 and 12 months. <b><i>Results:</i></b> Patients age was 50–83 years. 28 patients completed a 1-year follow-up with an intact device. Mean Qmax improved by 2 mL/s (25%), IPSS median drop was 10 points (40%), and QoL score was 1.5 points (38%). Sexually active patients reported antegrade ejaculation. On cystoscopy, gradual coverage of the devices with urethral mucosa was observed. In 1 patient, the device was repositioned. In 19 patients, the device was removed. 12 patients returned to alpha-blocker therapy and 7 patients underwent TURP. One patient developed a bulbar urethral stricture. <b><i>Conclusions:</i></b> We demonstrated feasibility and good tolerability of the Butterfly device.
