  • Rustin Massoudi, MD

    Rustin Massoudi, MD

    Clinical Assistant Professor, Urology

    BioDr. Massoudi is a board certified urologist specializing in general urology and urologic oncology. He is a clinical assistant professor of urology at Stanford University School of Medicine. Dr. Massoudi has expertise in treating prostate cancer, kidney cancer, kidney stones, and
    enlarged prostate. He also cares for patients with bladder cancer, testicular cancer, urinary retention, and a wide range of other urologic conditions.

    His experience encompasses the complete spectrum of treatment options. This includes advanced, minimally invasive techniques like endoscopy and laparoscopy, as well as robotic surgery, which can enable smaller incisions and potentially shorter recovery times. For cases where a minimally invasive approach isn’t feasible, he performs open surgery.

    Dr. Massoudi partners with each patient and family to customize a treatment plan that fits their needs. He welcomes patients at all stages in their journey—from early to more advanced symptoms—and is dedicated to helping them manage their urologic health long-term. He values the rewards of helping patients through difficult times as they cope with urologic disorders.

    Dr. Massoudi was drawn to urology for its unique combination of medical and surgical care, including the opportunity to use the most innovative techniques and technology. He enjoys establishing a rapport and staying in close communication with referring physicians. To ensure all of his patients receive comprehensive care, he collaborates with Stanford colleagues from endocrinology, nephrology, medical oncology, radiation oncology, and other specialties.

    Building on his passion for biological sciences and bioengineering, Dr. Massoudi’s studies have included translational research into the use of proteomics to target proteins on the metabolic pathway of kidney cancer development. In partnership with the Stanford Kidney Cancer Research Program, he has also explored the role of the molecule IQGAP in kidney cancer cell migration, proliferation, differentiation, polarity, and adhesion.

    While working at the Veterans Administration in Palo Alto, Dr. Massoudi collaborated on an investigation into the utility of nuclear imaging methods for identifying and staging bladder cancer. He also collaborated on research that used novel proteomic technology to understand the signaling mechanisms of renal cell carcinoma; he later performed in vitro experiments on novel biomarkers and therapeutic agents for treating it.

    Dr. Massoudi has authored numerous articles on renal disorders, innovative treatment techniques and technologies, and related topics. His work has been featured in Cell, the Journal of Endourology, European Urology Oncology, Canadian Journal of Urology, American Journal of Medical Genetics, and others. He has made presentations at conferences including the American Urological Association, Society of Urology Oncology, and World Congress of Endourology.

    Dr. Massoudi has received multiple honors for teaching, scholarship, and research including a Stanford Urology Teaching Award for Outstanding
    Mentorship of Co-Residents. In addition, he won a Gold Humanism and Excellence in Teaching Award from Stanford University School of Medicine.
    At the 43rd Annual Northern California Urological Society Conference, he won top honors for his presentation on IQGAP.
