Waterjet-based prostate resection (Aquablation procedure) is an increasingly recognized treatment for symptomatic benign prostatic hyperplasia (BPH). We confirmed the safety and effectiveness of the Aquablation procedure in the commercial setting in 178 men at five sites. The mean prostate volume was 59 cc. The procedure time averaged 24 min and total anesthesia duration was 50 min. The International Prostate Symptom Score (IPSS) decreased from 21.6 at the baseline to 6.5 at the 12-month follow-up, a 15.3-point improvement (p < 0.0001). The maximum urinary flow rate increased from 10 cc/s at the baseline to 20.8 cc/s at month 12 (increase of 11.8 cc, p < 0.0001). Ejaculatory function was relatively preserved. Prostate volume assessed with transrectal ultrasound decreased 36% by month three. Five patients (2.7%) underwent a transfusion in the first week after the procedure. Real-world evidence shows that Aquablation is safe and effective for the treatment of BPH.
