Abstract
An embodiment in accordance with the present invention provides a method for accurate and objective quantification of stone fragment size. The method includes intraoperative measurement of objects during URS. The method analyzes URS procedures for ureteral and renal stones during basket extraction of fragments. An instrument is passed through an instrument channel of the ureteroscope and advanced until it is adjacent to the stone fragment to be measured. The measurement of stone fragment size is based on the known distance of a tip of the instrument in the ureteroscope's visual field.
