Expert Urologic Care for Every Patient

Dr. Alfred Shtainer is an expert in the diagnosis and treatment of all diseases in men, women, and children related to the kidneys, bladder, prostate, and testicles.

Our clinic utilizes the most modern, state-of-the-art equipment to accurately diagnose urinary tract infections, kidney stones, impotence and premature ejaculation, incontinence, prostate diseases and cancer, blood in the urine, and male infertility.


We often use natural remedies to avoid side effects associated with most medications, and offer minimally invasive therapies including a 15-minute in-office procedure to reduce prostate size. We partner with top uro-oncologists, urogynecologists, infertility specialists, robotic surgeons, and stone specialists.


In-office Rapid STD/STI testing is available for Trichomonas, Candida, Gardnerella, Mycoplasma, Chlamydia, and Gonorrhea — results in just 15 minutes. Correct diagnosis is the shortest path to successful therapy.
