Why PeeDoc?


We’re Drs. Roscoe Nelson and Howard Tay. Our practice is formally known as Arizona State Urology but you can call us the “PeeDocs.” Yes, it’s a funny name for urologists in a medical profession with serious conditions like cancer, kidney stones, incontinence, infertility, and erectile dysfunction. However, by keeping things lighthearted, we can connect with more people; and by doing so, we are able to help more people. We love what we do because we simply love helping people. You can always expect honest, personal, and outstanding treatment from our staff and from us. Each patient is unique. Each patient is valuable. Each patient is more than just a name on a medical chart. We will strive to be the urologist you desire.


At Arizona State Urology we understand the complexities of the current medical environment. Information comes at you from many sources including TV, the Internet, advertisements and other sources making your medical decisions even more difficult. We try to help guide you through these difficult decisions.


The web site is intended to give you more knowledge about urology and related conditions. It’s not intended to offer treatment solutions for your or a family member’s particular medical condition or challenges. Instead, by exploring this site we hope that you will be more informed, and thereby gain more understanding and peace of mind.


Patient Portal


Patient PortalTo improve access to your medical records we would like to introduce you to the Arizona State Urology MeridianEMR patient portal. Our goal is to provide our patients with another option for communicating with our office.  Here you can send general messages, request a refill or request an appointment.  Please fill out your Portal Authorization Form and send it in to our office.  You can also find it in Spanish on our patient form page.
