Dr. Robert Star is a nephrologist practicing in Bethesda, MD. Dr. Star specializes in the care and treatment of the kidneys. As a nephrologist, Dr. Star most typically treats conditions like kidney stones, chronic kidney disease, acute renal failure, polycystuc kidney disease, high blood pressure and more. Nephrologists are also experts on kidney transplantation and dialysis. They are usually referred to by primary care physicians for problems related to the kidneys, and while they can perform tests to diagnose kidney disorders, they do not perform surgeries.

- How to Prevent UTIs
A urinary tract infection (UTI) is a common infection in any part of the urinary or renal system (urethra, ureters, bladder, and kidneys). In fact, it is the second most common type of infection among adults. Besides being responsible for over 8 million visits to healthcare professionals every year,...

- What Is a Kidney Biopsy?
A kidney biopsy, also called renal biopsy, is a medical procedure which involves taking a sample tissue of the kidney for laboratory analysis. This procedure helps your doctor know the type of disease on your kidney, how severe the disease is and the best treatment option. A kidney biopsy is also...
