We are a commercial-stage surgical robotics company focused on advancing patient care by developing transformative solutions in urology. We develop, manufacture and sell the AquaBeam Robotic System, an advanced, image-guided, surgical robotic system for use in minimally-invasive urologic surgery, with an initial focus on treating benign prostatic hyperplasia, or BPH. BPH is the most common prostate disease and impacts approximately 40 million men in the United States. Our proprietary AquaBeam Robotic System employs a single-use disposable handpiece to deliver our Aquablation therapy, which combines real-time, multidimensional imaging, personalized treatment planning, automated robotics and heat-free waterjet ablation for targeted and rapid removal of prostate tissue. We believe that Aquablation therapy represents a paradigm shift in the surgical treatment of BPH by addressing compromises associated with alternative surgical interventions.
We designed Aquablation therapy to deliver effective, safe and durable outcomes for males suffering from lower urinary tract symptoms, or LUTS, due to BPH that are independent of prostate size and shape or surgeon experience. We have developed a significant and growing body of clinical evidence, which includes nine clinical studies and over 100 peer-reviewed publications, supporting the benefits and clinical advantages of Aquablation therapy. As of June 30, 2021, we had an installed base of 124 AquaBeam Robotic Systems, and Aquablation therapy has been utilized in the treatment of more than 5,500 patients whose prostates have ranged in size from less than 30 ml to over 300 ml.
BPH refers to the non-malignant enlargement of the prostate gland, a small gland in the male reproductive system. The main role of the prostate is to produce the fluid that protects and gives nutrients to sperm. The prostate sits underneath the bladder and surrounds the top part of the urethra, which carries urine from the bladder. As the prostate enlarges, the gland presses against the urethra, which may obstruct or restrict the flow of urine from the bladder and result in uncomfortable LUTS, such as urgency, frequency, urinary retention, straining to urinate and a weak urinary stream. Without treatment, prolonged obstruction may eventually lead to acute urinary retention, urinary tract infections or renal insufficiency.
In the United States it is estimated that approximately 40 million men are impacted by symptoms of BPH, with aging demographics expected to drive future growth. Over the next ten years, it is expected that the number of men over 65 years old in the United States will double and include a corresponding increase in the number of men with enlarged prostates. Of these men, approximately 12 million are being managed by a physician for symptoms related to their disease.
Our total addressable patient population in the United States includes approximately 8.2 million patients, comprising 6.7 million receiving drug therapy, 1.1 million who have tried but failed drug therapy and 400,000 undergoing surgical intervention each year. Based on the average selling price of our single-use handpiece, we estimate that our total addressable market opportunity is in excess of $20 billion in the United States. The global incidence of BPH among men over 50 years old is similar to that of the United States, representing a significant incremental market opportunity outside of the United States.
