Endourology and Stone Disease

Conditions we treat within this category include:

  • Kidney stones

Endourology (stone disease) is a minimally invasive technique in which small telescopes and lasers are used to treat tumors, strictures, or congenital anomalies of the bladder, ureter, and kidney.

A kidney stone, also called nephrolithiasis, is a small, hard mineral and uric acid salt deposit that forms inside your kidneys and may affect any part of your urinary tract. When passed, kidney stones can cause severe pain. Most kidney stones may be treated without surgery, but in cases of persistent pain or infection, it may be necessary to remove the urinary obstruction.


Research is being pursued on treating tumors not only laparoscopically but also in an even less invasive manner—via radio frequency ablation and cryosurgery delivered percutaneously into small tumors. Ongoing research studies are also underway to evaluate the role, cost, and efficacy of various laparoscopy techniques. Quality improvement initiatives are underway to identify demographic and clinical variables associated with kidney stone formation and recurrence to develop interventions to reduce stone events in patients.

 Patient Care

Our physicians are dedicated to the thorough evaluation and minimally invasive treatment of stones, tumors, and congenital anomalies of the kidney, ureter, and bladder. The latest minimally invasive techniques are used to treat stones in the upper and lower urinary tract; these techniques include extracorporeal shock wave lithotripsy (ESWL) using two state of the art lithotripters.
