Stone Disease

Dr. Dinesh Singh
Yale Urology’s Stone Program offers a multidisciplinary, comprehensive approach to treating kidney stones in both adults and children. We are dedicated to offering our patients the most advanced diagnostic technologies and treatment strategies available. Our team continually integrates the latest in science-based medicine and innovative approaches into their practice to offer patients safer and more effective treatments.

Innovative Treatments

Our Stone Disease team uses non-invasive radiologic imaging, such as ultrasounds and CT scans to identify and quantify the stone burden. We use state-of-the-art treatment modalities, including incisionless stone ablation, and minimally invasive approaches using endoscopic or percutaneous techniques to break up and extract the stones. Some stones can be treated with non-invasive medical management. 

Our goal is to provide the safest and most effective treatment available. If surgery is needed, priority is placed on performing state-of-the-art procedures that are minimally invasive for the patient and offer the optimal outcome.

Forward Thinking

The Yale Stone Research Team, which is a multidisciplinary collaboration between urology, emergency medicine, biostatistics, and radiology, has been leading efforts to better manage patients who present with flank pain, identifying patients who need imaging, and in reducing radiation exposure for patients presenting with kidney stones who are often subjected to multiple and sometimes high dose CT scans. As a result of its implementation of its unique STONE Score, Yale has been able to filter patients to ultra low-dose CT scans, which provide nearly the same diagnosis as patients given the standard scan.

Our multidisciplinary team consists of urology, nephrology, and dietary experts, who work with our patients to help reduce future kidney stones. In fact, once someone has formed a kidney stone, odds increase to 50-50 that another will develop within the next ten years. We are dedicated to working with patients to make that probability more favorable to the patient. 

About Kidney Stones

Kidney stones are deposits of mineral and acid salts formed within the kidneys and can cause significant pain and obstruction as the stones passes from the kidney to the ureter on the way to the bladder. Kidney stones can be associated with kidney problems, infections, and they can impair kidney function. Kidney stones are thought to be a product of a diet high in salt and processed foods, but they are also associated with certain medical factors that leave some patients at a higher risk for stone formation. 

As part of our treatment program, we perform a comprehensive medical review to identify a patient’s risk factors for future development of kidney stones, and review dietary changes and medications to prevent or decrease recurrence rates.
