Dr Kenneth Hsiao (pronounced--Shaow) has been following me for prostrate/bladder issues for about…read more15 years. He has been nothing short of professional, thorough and kind in caring for this very sensitive area for men. For years, he had me on meds to deal with enlarged prostate issues, until those meds no longer did the trick. Together, we explored options and chose an Aquablasion procedure done in the hospital, to clean out the prostate gland and give a more healthy solution than medicine. That was in May of 2024. It was extremely successful and aside from him not allowing me to resume normal running, cycling and pushups, etc, for a month, it went flawlessly. That procedure was highly successful, and he handled himself like a true professional. Recently, I had bladder issues, and he was able to resolve them with precision and his care was exemplary. If you have Urological issues, I highly recommend getting in to see him. He is the consummate professional and bears the standard that health professionals should all follow.

I am in terrible pain from kidney stones right now and when I called to make an appointment with…read moreDr. Kenneth Hsiao the main receptionist of NorCal Urology was so extremely rude! Extremely! How she got a job there or anywhere for that matter I will never know. I really think someone should explain to her that she actually works in the medical field and people are actually in pain when they are trying to get in touch with the Drs. that work at this medical facility so a much more pleasant demeanor would be a lot more acceptable. This discourteous individual then proceeded to tell me that the Dr. doesn't have any appointments until a month from the time that I am actually calling, then basically hung up on me. I will never be recommending anyone to NorCal Urology and I will be letting my primary care doctor know how unprofessional and rude the front desk is over there as well, as they might not want to be referring patients to such an unnecessarily nasty experience. I then proceeded to make an appointment at a different establishment where the receptionist who answered was friendly and courteous and very thorough and this place will be seeing me by the end of the week. So no to ever wanting to go to or recommending anyone to NorCal Urology when there are so many other establishments that hire competent personable people who know how to answer a phone. If I could give zero stars I would!

After…read moreseveral discussions about shock wave therapy for helping with an enlarged prostate I decided to give it a try. I had already been going to a urologist for the past 2 1/2 years and tried several remedies without any help other than taking tamsulosin. My situation seemed to be getting worse with a diagnosis of prostatitis. Now, after 6 economical treatments, the results have been remarkable. Instead of taking forever to pee and never finishing till 9 or 10 squirts, I now have full comfort when I pee and am done after 2 or 3 squirts. I haven't felt this good for the last 3 years. Anyone with an enlarged prostate or prostatitis should have this done. Dr I can help you!!!
