The Aquabeam System: a Review
Purpose of Review
The purpose of this review is to provide a description of the Aquabeam system, the technique more commonly known as aquablation, and review the literature to date including select results from the unpublished WATER study to assess the efficacy and safety of this novel technique for the treatment of male lower urinary tract symptoms (LUTS) due to bladder outlet obstruction (BOO).
Promising outcomes from initial pilot studies and early clinical studies confirming safety and feasibility have led to the large international multi-centre randomised controlled study known as the WATER study. This compared the Aquabeam system to the current gold standard, transurethral resection of the prostate (TURP). This landmark trial has proven that aquablation equals TURP in clinical efficacy and has superior safety outcomes, particularly for larger prostates.
Aquablation is not only a technically feasible and safe procedure for symptomatic male BOO, but has equivalent efficacy to TURP with a better safety profile. Ongoing trials are taking place to confirm aquablation’s role in the spectrum of minimally invasive treatments for male LUTS.
