Urodynamic Outcomes After Aquablation

Published:February 02, 2019DOI:



      To compare urodynamic outcomes between Aquablation vs transurethral resection of the prostate (TURP).


      Patients were randomized 2:1 (Aquablation:TURP) in the Waterjet Ablation Therapy for Endoscopic Resection of prostate tissue study. Urodynamics were measured at baseline and 6 months.


      Urodynamics studies were performed in 66 of the participating subjects at baseline and 6 month follow-up. At mean baseline [email protected] was 71 and 73cm H20 in the Aquablation and TURP groups, respectively (P = .7031). At 6-month follow-up, [email protected] decreased by 35 and 34cm H20, respectively (P < .0001 compared to baseline for both arms) with no significant difference in decrease across groups (P = .8919). A large negative shift in Bladder Outlet Obstruction Index was observed, consistent with a large reduction in the proportion of subjects with obstruction at follow-up compared to baseline (79% to 22% in Aquablation and 96% to 22% in TURP).


      In this trial, improvements after Aquablation in objective measures of bladder outlet obstruction were similar to those observed after TURP. number, NCT02505919
