What are the risks?

All treatments have inherent and associated risks. The Water Vapor Therapy System is intended to relieve symptoms and obstructions, and reduce prostate tissue associated with BPH. The Water Vapor Therapy System is also indicated for treatment of prostate with hyperplasia of the central zone and/or a median lobe. Potential risks include but are not limited to painful urination (dysuria), blood in the urine (hematuria), blood in the semen (hematospermia), decrease in ejaculatory volume, suspected urinary tract infection (UTI), and urinary frequency, retention or urgency. You should talk with your doctor or urologist about benefits and risks before moving forward with any treatment option.
