title: Percutaneous nephrostomy in the treatment of renal calculi.
abstract: We have described two cases of nonoperative removal of obstructing ureteral calculi via a percutaneously placed nephrostomy. Nephrectomy or excessive operative morbidity and mortality may thus be avoided in patients at high risk. Although the number of patients who have been treated in this manner is small, the results are encouraging.
