OBJECTIVE: To report real-world experience of 4-year safety and efficacy outcomes of Aquablation procedure for the treatment of men with symptomatic benign prostatic hyperplasia (BPH).
METHODS: This is a prospective single-center, observational study evaluating the outcomes of robotic-assisted Aquablation therapy for moderate-to-severe BPH between December 2019 and December 2023. Patient-level data included age, prostate volume, IPSS score, peak urinary flow rate (Qmax), post-void residual (PVR) were evaluated at 3 M, 6 M, and Years 1-4. Primary outcomes included change in IPSS score, change in Qmax, change in PVR, preservation of antegrade ejaculation, and complications.
RESULTS: In this cohort of 330 men, mean prostatic volume was 110.3 mL (range 38-330 mL) at baseline. International Prostate Symptom Score (IPSS) improved from a baseline of 23.8 (SD 8.4) to 6.9 (SD 2.9) at 4 years. Mean peak urinary flow rate (Qmax) also demonstrated improvement and increased from 6.4 mL/sec (SD 4.2) to 17.4 mL/sec (SD 5.5) at 4 years. At 1 year, mean prostate volume reduction was 45.5 mL (-41.3%). Postoperative antegrade ejaculation was preserved in 249/250 men (99.6)% of men. Complications included urinary tract infection within first month after procedure in 37 (11.2%) and bleeding requiring blood transfusion in 11 (3.3%). Thirteen patients (3.9%) required a second procedure including 2 for post-operative bleeding, 1 for a bladder neck disruption and 10 (3.0%) for transurethral resection of residual anterior tissue.
CONCLUSION: We demonstrate Aquablation to not only be safe but also providing durable outcomes at 4 years for men with BPH.
