WATER: A Double-Blind, Randomized, Controlled Trial of Aquablation ® vs Transurethral Resection of the Prostate in Benign Prostatic Hyperplasia

Surgical prostate resection using Aquablation showed noninferior symptom relief compared to transurethral prostate resection but with a lower risk of sexual dysfunction. Larger prostates (50 to 80 ml) demonstrated a more pronounced superior safety and efficacy benefit. Longer term followup would help assess the clinical value of Aquablation.
