Endourology, Kidney Stone and Lithotriptor Program

The Endourology Division of the Department of Urology at the University of Michigan is committed to providing excellent care for people with urinary stones and other urologic problems amenable to an endoscopic approach, such as upper urinary tract tumors and obstructions. We intend to evaluate you and manage your problem quickly, efficiently and effectively. We aim to minimize the duration of the period from symptom onset to resolution of the problem, and to resolve the problem with minimally-invasive techniques that are individualized for your specific situation.

Extracorporeal Shockwave Lithotripsy for Small Urinary Stones

Small urinary stones can be treated with the totally non-invasive method of extracorporeal shockwave lithotripsy, where stones are broken up by shock waves that pass through the skin.

Ureteroscopy with Laser Lithotripsy for Almost Any Urinary Stone

Ureteroscopy is the use of a small endoscope placed through the urethra and bladder, up into the ureter and kidney, to address the majority of stones. This technique is especially useful for frequently recurrent stones or stones that have been resistant to extracorporeal shockwave lithotripsy. Ureteroscopy is also used for upper urinary tract tumors and obstructions.

Percutaneous removal of Large Urinary Stones

Percutaneous stone removal is used for the very largest and most complicated stones. On rare occasions, laparoscopic techniques might be considered as well.

Surgical Volume

As a referral center (click here to see our regional referral patterns), ureteroscopy is the most common procedure that we perform. The figure (see attachment), demonstrates our volume of Endourology procedures at the University of Michigan from 2008 through 2012. Our activity has increased 44% in 4 years, performing over one thousand procedures in 2012. The volume of extracorporeal shockwave lithotripsy has increased 27%, ureteroscopy has increased 44% and percutaneous stone removal has increased 65%.

Medical Stone Prevention

We will help you by not only addressing the stones that you may have inside you right now, but also by creating a personalized program to prevent stone formation in the future. There are many metabolic causes of stones, in various combinations, and we will determine your specific metabolic problem and work with you to address it with diet or medications. If you have frequent stone recurrences, multiple medical problems, or additional urologic problems such as neurogenic bladder, chronic infection or obstruction, then our comprehensive program is particularly well suited for you.
