Optilume drug-coated balloon for anterior urethral stricture: 2-year results of the ROBUST III trial.

Objective: The aim of this study is to report the updated 2-year results of the intervention arm of the ROBUST III randomized trial evaluating the safety and efficacy of the Optilume drug-coated balloon (DCB) versus standard endoscopic management of recurrent male anterior urethral stricture.

Materials And Methods: Eligible patients included men with recurrent anterior urethral stricture ≤3 cm in length and ≤12Fr in diameter, International Prostate Symptom Score (IPSS) ≥11 and peak flow rate (Qmax) <15 mL/s. Patients were randomized to treatment with the Optilume DCB or standard-of-care endoscopic management.

Prospective Trial of Water Vapor Thermal Therapy for Treatment of Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia in Subjects with a Large Prostate: 6- and 12-month Outcomes.

Background: Current guidelines recommend Rezūm water vapor thermal therapy for the treatment of benign prostatic hyperplasia (BPH) for prostate glands ranging in volume from 30 to 80 cm. Few prospective studies have specifically evaluated the use of Rezūm for larger prostates.

Objective: To evaluate the safety and efficacy of water vapor thermal therapy in patients with a prostate gland >80 cm and ≤150 cm.

Transurethral Vapor Ablation in Patients with Intermediate-Risk Localized Prostate Cancer.

We report results of a prospective, multicenter single-arm study of transurethral vapor ablation (TUVA) of prostate tissue in patients with unilateral, intermediate-risk, localized prostate cancer (PCa). Men ≥45 years of age with biopsy-confirmed unilateral Gleason grade group 2 (GGG2) adenocarcinoma of the prostate, prostate volume of 20-80 cc, and prostate-specific antigen (PSA) ≤15 ng/mL were enrolled. Cystoscopy and transrectal ultrasound (TRUS) guidance were used to deliver ∼103°C water vapor to prostate zones for unilateral hemigland ablation, including destruction of cancers detected by multiparametric MRI (mpMRI) and confirmed by biopsy.

One-Year Results for the ROBUST III Randomized Controlled Trial Evaluating the Optilume Drug-Coated Balloon for Anterior Urethral Strictures.

Purpose: The Optilume® drug-coated balloon (DCB) is a urethral dilation balloon with a paclitaxel coating that combines mechanical dilation for immediate symptomatic relief with local drug delivery to maintain urethral patency. The ROBUST III study is a randomized, single-blind trial evaluating the safety and efficacy of the Optilume DCB against endoscopic management of recurrent anterior urethral strictures.

Materials And Methods: Eligible patients were adult males with anterior strictures ≤12Fr in diameter and ≤3 cm in length, at least 2 prior endoscopic treatments, International Prostate Symptom Score ≥11 and maximum flow rate <15 ml per second.

Final 5-Year Outcomes of the Multicenter Randomized Sham-Controlled Trial of a Water Vapor Thermal Therapy for Treatment of Moderate to Severe Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.

Purpose: We present final 5-year outcomes of the multicenter randomized sham-controlled trial of a water vapor therapy (Rezūm™) for treatment of moderate to severe lower urinary tract symptoms due to benign prostatic hyperplasia.

Materials And Methods: A total of 197 subjects 50 years of age with International Prostate Symptom Score ≥13, maximum flow rate ≤15 ml/second and prostate volume 30 to 80 cc were randomized and followed for 5 years. From the control arm of 61 subjects, a subset of 53 subjects requalified and after 3 months received treatment as part of the crossover group and were also followed for 5 years.

The Rezūm system - a minimally invasive water vapor thermal therapy for obstructive benign prostatic hyperplasia.

Benign prostatic hyperplasia (BPH) and accompanying lower urinary tract symptoms (LUTS) sits in the top ten prominent and costly disease conditions in men over 50 years of age. In the United States it is the most common diagnosis made by urologists for men 45 to 74 years of age. Twenty percent of the population will reach 65 years of age or older by 2030, and those over 85 years will represent the fastest growing segment of our population.

Convective Thermal Therapy: Durable 2-Year Results of Randomized Controlled and Prospective Crossover Studies for Treatment of Lower Urinary Tract Symptoms Due to Benign Prostatic Hyperplasia.

Purpose: We report 2-year outcomes of a multicenter randomized controlled trial plus 1-year results of a crossover trial after treatment with convective radiofrequency water vapor thermal energy for lower urinary tract symptoms due to benign prostatic hyperplasia.

Materials And Methods: A total of 197 men at least 50 years old with I-PSS (International Prostate Symptom Score) 13 or greater, maximum flow rate 15 ml per second or less and prostate size 30 to 80 cc were randomized 2:1 to thermal therapy with the Rezūm® System or a control group. Rigid cystoscopy with simulated active treatment sounds served as the control procedure.

Erectile and Ejaculatory Function Preserved With Convective Water Vapor Energy Treatment of Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia: Randomized Controlled Study.

Introduction: Most surgical treatments for male lower urinary tract symptoms and benign prostatic hyperplasia affect erectile and ejaculatory functions negatively, leading to patient dissatisfaction.

Aim: To determine whether water vapor thermal therapy, when conducted in a randomized controlled trial, would significantly improve lower urinary tract symptoms secondary to benign prostatic hyperplasia and urinary flow rate while preserving erectile and ejaculatory functions.

Methods: Men at least 50 years old with International Prostate Symptom Scores of at least 13, a peak flow rate of at least 5 to no higher than 15 mL/s, and prostate volume of 30 to 80 cm(3) were randomized 2:1 between Rezūm System thermal therapy and control.

Minimally Invasive Prostate Convective Water Vapor Energy Ablation: A Multicenter, Randomized, Controlled Study for the Treatment of Lower Urinary Tract Symptoms Secondary to Benign Prostatic Hyperplasia.

Purpose: This report reveals the results of a multicenter, randomized, controlled study using transurethral prostate convective water vapor thermal energy to treat lower urinary tract symptoms associated with benign prostatic hyperplasia.

Materials And Methods: Men 50 years old or older with an International Prostate Symptom Score of 13 or greater, maximum flow rate of 15 ml per second or less and prostate size 30 to 80 cc were randomized 2:1 between thermal therapy with the Rezūm® System and control. Thermal water vapor was injected into the transition zone and median lobe as needed.
