Benign prostate hyperplasia is a benign tumor that grows in the in the prostate gland in the center the prostate gland and closes up the urine tube the urethra so that it blocks the flow of urine from the bladder. Usually it's a slow onset and usually men in their 50s and 60s start experiencing that where they have to get up more at night and their urine stream is slowed while they can't empty their bladder completely. So there are a lot of treatment options for BPA. One is active surveillance, just watching it. A lot of patients don't require any treatment at all. We have medications that can help for mild to moderate cases of BPH. And then for patients who have whose symptoms are more bothersome there's surgery. We have several minimally invasive surgical options that includes a UroLift which is a prosthetic implant to help open up the prostate gland. We have laser surgery called Greenlight laser surgery that basically we nucleate the prostate or evaporate the prostate tissue out of the lining of the urethra. Then we have, for very large and more advanced cases, we can offer a nucleation in surgery where we actually remove the inner lining of the prostate and we can do that either with the da Vinci robot or with endoscopic means with a scope through the urethra called the HoLEP procedure. I've been in urology for 30 years. My colleagues also have a tremendous amount of experience and we also have a lot of collaboration with other departments so it really comes down to we have all the options and a lot of minimally invasive options for them.
