Kidney stones are usually evaluated and treatments are recommended by a urologist. I am a nephrologist and do not treat kidney stones surgically. A nephrologist would evaluate you and determine if there is anything that could be done to prevent a kidney stone, but would not be able to recommend treatment for an existing stone without consulting with a urologist. If the urologist wants you to consult with a nephrologist, you may have to ask for a referral. You should also discuss your concerns with your primary care physician (PCP).
