Groundbreaking Research and Clinical Trials

Dr. Pattaras started the Division of Minimally Invasive Surgery within the Department of Urology in 2000. Since then, the standard treatment of urologic cancers and diseases is almost now done exclusively with robotics or laparoscopic surgery, allowing quicker patient recovery.

Dr. Pattaras has done extensive research in the treatment of kidney cancer and has one of the nation’s largest experiences of renal cryotherapy, which allows treatment of kidney cancer and preservation of the remaining kidney. This cancer treatment now allows the patients to retain viable healthy kidney not affected by cancer. The treatment usually involves an overnight stay in the hospital.

With the integration of robotics to Emory, Dr. Pattaras was the first to perform a robotic prostatectomy, robotic partial nephrectomy (removal of kidney tumor and kidney reconstruction) and robotic cystoprostatectomy for aggressive bladder cancer. Robotics was a natural transition from laparoscopic surgery.

Dr. Pattaras is also the co-director of the Emory Kidney Stone Center, which offers the latest endoscopic treatments for even difficult to treat kidney stones. Non-invasive shock wave lithotripsy is available on an urgent basis. Emory Kidney Stone Center also offers diagnostic testing of patients and an analysis of a stone prevention plan customized to the patient. Dr. Pattaras has performed clinical trials focused on improving the treatment and prevention of kidney stones.

Dr. Pattaras spoke Greek as his first language but was born in New York City to parents of immigrants. He still has family in Greece and travels back to see them every few years. Dr. Pattaras has resided in Atlanta since 2000, where he met his wife Kristy. They had their daughter in 2010.

Dr. Pattaras became interested in minimally invasive surgery when laparoscopy was in its infancy. He completed his residency and fellowships and was hired as the first member of the newly formed Department of Urology to head Minimally Invasive Surgery. His continued interest in oncologic surgery and reconstruction are his main research interests.
