Lambros Stamatakis

Lambros Stamatakis, MD, is director, Urologic Oncology, MedStar Washington Hospital Center (MWHC), and an assistant professor of Urology, Georgetown University.

Dr. Stamatakis is interested in the diagnosis and management of malignant diseases of the urologic system, including the bladder, kidney, prostate, and testes. He is skilled in performing radical cystectomy and urinary diversion, radical nephrectomy, partial nephrectomy, radical prostatectomy, and other complex procedures involving the urologic system. His surgical expertise extends to open, endoscopic, and minimally invasive (laparoscopic and robotic) urologic procedures.

Dr. Stamatakis provides individualized state-of-the-art urologic oncologic care, using minimally invasive laparoscopic and robotic techniques when possible. He helps to coordinate care teams as needed, engaging medical and radiation oncology, as well as pathology, behavioral health, and social services, to provide comprehensive multidisciplinary cancer care to patients. His goal is not only to be a physician and surgeon for his patients, but to be an advocate as well.

His research has been published in peer-reviewed journals, including Cancer, Urology, Urologic Oncology, The Journal of Urology, and BMJ Case Reports. He reviews manuscripts for Urologic Oncology, Urology, and BJU International. At MedStar, he serves on the Urology Program Evaluation Committee and the robotics steering committee. In addition, he is a member of the American Urological Association and the Society of Urologic Oncology.

His medical degree is from the University of Maryland School of Medicine. He completed an internship in general surgery, a residency in urology, and a fellowship in endourology and minimally invasive surgery at Baylor College of Medicine in Houston, TX. He then completed an additional fellowship in urologic oncology at the National Cancer Institute, where he concentrated on initiating and conducting clinical trials. In addition to English, Dr. Stamatakis has conversational skills in Greek.

Research Interests

Dr. Stamatakis’s research interests include the following:

  • Non-muscle invasive bladder cancer
  • Muscle-invasive bladder cancer
  • Urothelial carcinoma of the upper urinary tract
  • Bladder hemorrhage
  • Bladder mass
  • Kidney cancer

Selected Research

Dr. Stamatakis is currently conducting research at MWHC on an investigational agent for patients with bacillus Calmette-Guerin (BCG)-unresponsive non-muscle invasive bladder cancer. He is developing a new study, in collaboration with the National Cancer Institute, to investigate the role of neoadjuvant immune checkpoint inhibitors and radiation therapy prior to radical cystectomy for muscle-invasive bladder cancer.
