The Aquablation therapy is a minimally invasive, image-guided, heat-free robotic therapy delivered by the AQUABEAM Robotic System. During Aquablation therapy, the AQUABEAM Handpiece is inserted transurethrally into the prostatic urethra. The operating physician then utilizes cystoscopy in conjunction with transrectal ultrasound (TRUS) imaging for real time visualization. The AQUABEAM Robotic System utilizes high-velocity sterile saline waterjet to resect and remove the prostate tissue according to the operating physician's treatment plan.
