Assessing medium-term functional results of a novel minimally-invasive treatment for lower urinary tract symptoms due to BPO with the second generation of the temporary implantable nitinol device (iTind; Medi-Tate Ltd®, Israel): 2-year follow-up of a single-arm, prospective, international multicenter study. Further, we aimed to identify preoperative baseline parameters predicting response to iTind treatment. Following local ethical committee approval in every participating centre, 81 men with symptomatic BPO (IPSS ≥ 10, peak urinary flow 250 ml, obstructive median lobe, previous prostatic surgery, confounding bladder or sphincter dysfunction based on medical history, active urinary infection and unable to interrupt antithrombotic or antiplatelet treatment were exclusion criteria. A wash-out period of 1 month for alpha-blockers and 6 months for 5-ARIs was mandatory to avoid confounders. The procedure was performed as previously described: implantation under light sedation and removal 5–7 days later with topical sedation. Patients were assessed for perioperative results including OR-time, pain (VAS) and complications (Clavien–Dindo-Grading System); and for functional results (PVR, Qmax, IPSS) and quality of life (QoL) including sexual and ejaculatory function using two yes/no questions. Follow-up assessments were done at 1, 3, and 6 months, and 1 and 2 years. Of the 81 patients initially enrolled in this study, follow-up included 67 men at 1 year and 51 men at 2 years. For the 51 men included in the present analysis, the median age was 65 years, median prostate volume 37 ml (range 16–65 ml). Baseline values for IPSS and QoL were 20.51 ± 4.58, 3.96 ± 0.87. Qmax and PVR were 7.62 ± 2.25 ml/s and 65.84 ± 38.46, respectively. No intraoperative complications were observed and the average pain level recorded on the visual analogue scale (VAS) was 3.2 ± 1.6. A significant reduction in symptoms and improvement in urinary flow was observed (p
