The sizes of the kidney stones might deserve either radiologic treatment like use of laser in lithography, or use of surgery. Surgery must not be invasive in this case for there exist endoscopic surgery, which can be well-used in this case. Thanks and kind regards. I suggest you consult a urologist. Bain LE, MD.
