About Dr. Pattaras

Dr. Pattaras is an Associate Professor of Urology at the Emory University School of Medicine, Chief of Emory Urology services at Saint Joseph’s Hospital and Director of Minimally Invasive Surgery.

Dr. Pattaras attended Johns Hopkins University for his undergraduate education (BA in Biology). He received his medical degree and urology residency training at George Washington University School of Medicine. He attended the National Cancer Institute/National Institutes of Health for research fellowship in Biotechnology focusing on prostate cancer. Dr. Pattaras received Endourology and Laparoscopy fellowship training at St. Louis University Medical Center. Dr. Pattaras is a diplomate of the American Board of Urology (2002) a Fellow of the American College of Surgery.

As the Director of Minimally Invasive Surgery, Dr. Pattaras started laparoscopic and robotic urologic surgery program at Emory University. Over the past 14 years, the program has expanded to become the premier laparoscopic and robotics program in Atlanta serving patients from Georgia, neighboring states as well as international patients. The program offers highly specialized minimally invasive surgery that includes organ-sparing cancer surgery and complex stone surgery. Patients attending Emory Urology for cancer treatment have the unique opportunity to be cured of their disease while at the same time preserve their vital organs, their functionality and quality of life.

Dr. Pattaras’s clinical and research interests include minimally invasive cancer and stone surgery, endourology, laparoscopy and robotic surgery. He has lectured both nationally and internationally. He is closely involved in teaching and mentoring medical students, urology residents and post-graduate fellows. He has authored multiple book chapters, and scientific journal articles.

In addition to his dedication to Emory patients, Dr. Pattaras is also involved in humanitarianism outside Emory. On an annual basis, he volunteers his time to organize and head a team of Emory medical students to Haiti. The team provides free urologic care including surgical treatment to indigent Haitian patients with urologic conditions.
