[Prostatic urethral lift using Urolift® system for benign prostatic hyperplasia: 7years experience]. / Pose d'implants Urolift® intra-prostatique pour hyperplasie bénigne de la prostate : résultats après 7 ans d'expérience.

INTRODUCTION: Urolift® system is a mini-invasive technique, proposed as an alternative treatment for classic surgery of benign prostatic hyperplasia (BPH). Our objective was to report the results of Urolift® system in our center after 7years experience. PATIENTS AND METHODS: Urolift® implants were proposed between February 2012 and March 2019 for patients presenting symptomatic BPH in our center, as an alternative for classic surgery. The efficacy was evaluated with questionnaires about lower urinary tract symptoms (IPSS) and its impact on quality of life (IPSS-QdV). Tolerance was evaluated with questionnaires about erectile (IIEF5) and ejaculatory function (MSHQ-EjD) and complication rate. Survival without additional treatment was assessed using Kaplan-Meier method. RESULTS: Forty patients were treated during this period, with a median follow-up of 32months [12-67]. Three months after the procedure, IPSS and IPSS-QdV were significantly improved (respectively 8 [4-11] vs 20 [17-24]; P<0.0001 and 2 [1-2] vs 5 [4-6]; P<0.0001). MSHQ-EjD and IIEF5 were not modified (respectively 13 [11-14] vs 12 [9-13]; P=0.69 and 21 [18-23] vs 21 [18-23]; P=0.13). Two patients (5%) experienced a urinary retention and needed a bladder catheter. No complication with a Clavien-Dindo score>2 were reported. Survival without additional treatment at 5years was 63%. CONCLUSION: Urolift® implants improved significantly the lower urinary tract symptoms in our population, with a good tolerance profile. More than 60% of the patients did not need an additional treatment after 5years of follow-up. LEVEL OF EVIDENCE: 3.

[Are the UroLift(®) implants an alternative for the treatment of benign prostatic hyperplasia? Short-term results and predictive factors of failure]. / La pose d'implants intra-prostatiques UroLift(®) est-elle une alternative chez les patients ayant une hyperplasie bénigne de la prostate ? Résultats initiaux et facteurs prédictifs d'échec.

OBJECTIVE: To report the results of UroLift(®) implants after a 2-year experience in the technique. PATIENTS AND METHODS: The procedure was proposed between February 2012 and April 2014 in patients with symptomatic benign prostatic hyperplasia, as an alternative to standard endoscopic ablation techniques. Evaluation of BPH related symptoms relied on the IPSS and IPSS-QoL self-questionnaires, as well as on maximum uroflow (Qmax). Evaluation of erectile and ejaculatory functions relied on the IIEF5 and MSHQ-EjD self-questionnaires, respectively. RESULTS: A total of 23 patients were treated during this period. Median age was 66 years [53-78]. Median prostate volume was 38mL [20-80]. Preoperative IPSS and IPSS-QoL were 20 [9-29] and 5 [3-6], respectively. No severe adverse event was observed postoperatively. Median follow-up was 14 [5-31] months. At the end of follow-up, 19 (83%) patients reported sustained symptomatic improvement without any additional treatment. Median IPSS and IPSS-QoL were improved significantly (11 [1-27] and 2 [0-6], P<0.0001), with however no significant improvement in Qmax. Four patients needed additional treatment during the first postoperative year. Among them, 3 had a prostate volume>60mL. No patient reported retrograde ejaculation or worsened erectile function. CONCLUSIONS: UroLift(®) implants allowed symptomatic improvement in more than 80% of the patients after 1-year follow-up. A high prostate volume may potentially be predictive of symptomatic failure. LEVEL OF PROOF: 5.
