The practice of Katz and Hayne, M.D. Inc., has been offering the San Francisco peninsula the finest in urological care for over 30 years. We strive to provide state-of-the-art diagnosis and treatment. We specialize in treating prostate cancer, bladder cancer, kidney stones, erectile dysfunction, incontinence, infertility, and other urologic disorders. Our top tests and procedures include prostate biopsy, vasclip, vasectomy, and cystoscopy. Our decades of experience have taught us to treat each patient as an individual and a partner in his or her medical care. We are aware that many urological conditions are accompanied by social discomfort or embarrassment, so we approach all patients with particular sensitivity and discretion.
