Stone removal surgery - ureteral stones, kidney stones (URS, FURS)
Endoscopic stone removal within the ureter using a ureterorenoscope (URS) or flexible ureterorenoscope (FURS) is necessary when a stone becomes lodged in the ureter or renal pelvis and cannot be removed or fails to pass on its own using conservative treatment methods (e.g., drinking plenty of fluids, exercise, medication).
