My mother had a pain and the CAT KUB report says that there is mild to moderate dilatation of left pelvicalyceal system and left ureter is noted secondary to a small hyperdense calculus in the distal most part of left ureter just adjacent to the left ureterovesical junction, measuring 5.7*4.6 mms. The doctor suggested 3 methods : 1)Through medication 2) Applying force through glucose 3) uteroscopy Which one should I go for??
