About me

Dr. David T. Tzou is a urologist who specializes in providing care for patients with complex kidney stone disease and men with urinary symptoms related to an enlarged prostate. He specializes in minimally invasive surgical treatments for these conditions and often cares for patients with medically complex or high-risk stone disease. He emphasizes clear communication and shared decision-making to help patients understand their condition and treatment options so they can make informed choices about their care.  

Tzou’s research focuses on better understanding why certain kidney stones are associated with infection, complex surgeries, as well as serious complications such as sepsis and prolonged recovery. His work aims to improve the safety of stone surgery by identifying infection risks earlier and developing strategies to reduce complications before, during and after treatment.

Tzou earned his medical degree from the University of Arizona College of Medicine, where he also completed a residency in urology. He completed a fellowship in endourology at UCSF. He is a member of the EDGE Research Consortium and the Kidney Stone Collaborative.

      He was excellent, took time to answer my questions, eased my fears and was one of the better doctors I've ever dealt with. I usually don't fill these surveys out but I was so impressed with the doctor I felt the need to!

      He was great, caring and made what sounds like a few very painful procedures sound doable.
