Stone Disease

Sophisticated patient management

Endorology is a subspecialty of urology where a urologist uses an endoscopic camera to see inside the urinary system and perform surgery on those organs (kidneys, ureters, bladder, urethra). 

Common conditions treated using endourologic techniques are:
Kidney stones, bladder stones, strictures (scar tissue), and benign prostatic hyperplasia.

Examples of procedures include ureteroscopy with laser lithotripsy (stone breakage) and basket extraction, percuteanous nephrolithotomy, laser endopyelotomy (treatment of ureteropelvic junction obstruction), and laser endoureterotomy (treatment of ureteric strictures).

Stone disease can be treated surgically and medically.  Surgical treatments include extracorporeal shockwave lithotripsy, ureteroscopy, and percuteanous nephrolithotomy.  Medical assessment includes an assessment of dietary and fluid habits, blood work to assess for underlying medical conditions that can contribute to kidney stones, and 24 hour urine collections to assess the urine composition with respect to kidney stone promoters and inhibitors.  Patients will receive dietary counselling for kidney stone prevention and some patients may go on medications or supplements to help decrease their kidney stone formation.
