The UCI Kidney Stone Center is led by kidney stone specialists Dr. Jaime Landman and Dr. Ralph V. Clayman, world-renown pioneers in the development of minimally invasive surgery, with over 9 decades of combined experience managing kidney stones. The specially trained team also includes Drs. Roshan M. Patel and Ramy F. Yaacoub. We strive to offer treatment by a kidney stone doctor 48-72 hours after diagnosis with access to a dedicated kidney stone surgical suite 5 days per week.
