The U-M Department of Urology has long been a pioneer and a force for innovation within Endourology.  

The Mission of the Endourology Division is to optimize the treatment and prevention of urolithiasis and other endourological conditions.

We strive to realize this mission by:

  • Delivering excellent clinical care:
    • Unique expertise for complex cases
    • Best service/access for standard cases
  • Continual innovation and refinement in our:
    • Delivery of clinical care and quality assessment
    • Research
    • Education
  • Providing comprehensive, state of the art education across the spectrum of endourology.

Today, our Division of Endourology is among the largest in the country — with five urologists who specialize in adult endourology, and another who specializes in pediatric endourology.  Each year, we perform approximately 1,200 ureteroscopic procedures and 200 percutaneous procedures, including the treatment of calculi and the endurologic management of tumors and strictures.

For the highest-quality urinary stone care, excellent surgical treatment is not enough. Ours is a comprehensive kidney stone center; we have great interest and expertise in the metabolic evaluation and treatment for urinary stone prevention. Our Division is also very proud of our standardized management protocols including ones for pre- and post-operative management of patients undergoing ureteroscopy, percutaneous surgery, and extracorporeal shock wave lithotripsy.

We also have a very active laparoscopic and robotic surgery program. In 2017 we performed nearly 150 laparoscopic or robotic upper urinary tract procedures. Our most common laparoscopic/robotic operations are ureteral reconstruction and pyeloplasty.
