Full Definition
A ureteroscope is a specialized endoscopic instrument designed for direct visualization and treatment of the ureter and intrarenal collecting system. Modern ureteroscopes are available in both rigid and flexible varieties, with flexible scopes allowing access to all parts of the kidney. These instruments feature working channels that accommodate various tools including laser fibers, baskets, and graspers for stone removal, biopsy forceps, and electrocautery devices. Ureteroscopes have revolutionized the treatment of upper urinary tract stones and allow for minimally invasive management of ureteral strictures and upper tract tumors.
Usage
Usage note: Specify rigid vs. flexible when relevant to the procedure.
