TL;DR: Of 582 patients who underwent percutaneous nephrolithotomy, 4% had complications and there were two deaths--one from respiratory failure in a patient with severe interstitial pulmonary fibrosis and chronic renal failure and the other from myocardial infarction in an obese diabetic patient with hypertension.

TL;DR: The first 100 cases at this institution were reviewed in which grasping, ultrasonic lithotripsy, basketing, and irrigation were used, and the short-term results of percutaneous stone removal have been as good as those of open surgery.
