Abstract

Objective: To report 4-year outcomes of the randomized controlled trial of water vapor thermal therapy for treatment of moderate to severe lower urinary tract symptoms due to benign prostatic hyperplasia. Materials and Methods: Total 188 subjects; 135 men ≥50years old, International Prostate Symptom Score ≥ 13, maximum flow rate (Qmax) ≤15 mL/s and prostate volume 30 to 80 cc treated with Rezūm System thermal therapy were followed 4 years; subset of 53 men who requalified for crossover from control to active treatment were followed 3years. Results: Lower urinary tract symptoms were significantly improved within ≤3 months after thermal therapy and remained consistently durable (International Prostate Symptom Score 47%, quality of life 43%, Qmax 50%, Benign Prostatic Hyperplasia Impact Index 52%) throughout 4years (P <.0001); outcomes were similarly sustained in crossover subjects at 3years. Surgical retreatment rate was 4.4% over 4years. No disturbances in sexual function were reported. Conclusion: The minimally invasive thermal therapy provides effective symptom relief and improved quality of life that remains durable for over 4years. It is applicable to all prostate zones with procedures performed under local anesthesia in an office setting.
