Sima Porten


Urologic cancer surgeon
Mom, bladder and kidney cancer researcher, dance lover

Dr. Sima Porten is a specialist in cancers of the genital and urinary organs. She is a member of the urologic oncology team at the UCSF Helen Diller Family Comprehensive Cancer Center. Her clinical interests include the diagnosis and treatment of genitourinary cancer, particularly bladder cancer, upper tract urothelial cancer, kidney cancer and high-risk prostate cancer.

Porten's research focuses mainly on the diagnosis and management of urothelial carcinoma, a cancer involving parts of the kidney, bladder and ureter (the tube connecting each kidney to the bladder). In studying the biologic or genetic basis of urothelial carcinoma, she hopes to develop new tests and treatments to bring personalized medicine to patients with bladder cancer.

Porten received her undergraduate, medical and master of public health degrees from Northwestern University. During medical school, she was inducted into the Alpha Omega Alpha Honor Medical Society and also completed a fellowship through the Howard Hughes Medical Institute–National Institutes of Health Research Scholars Program. She then completed her urology residency training at UCSF, where she received the Julius R. Krevans Award for Clinical Excellence. During her training in urologic oncology at the University of Texas MD Anderson Cancer Center, she was awarded a John Quale Travel Fellowship for her research in bladder cancer.

Porten is an active member of the American Urological Association, American Society of Clinical Oncology, Society of Women in Urology and Society of Urologic Oncology.

    Dr. Porten proposed Gem/Doc procedure for my 5 cm NMIBC tumor. Her team perfectly executed it and at the end of the cystoscopy with monitor In front of my eyes she told me that there Is no detectable tumors there.
