[Our results with percutaneous nephrolithotomy. Report of 61 cases].

Between January 1990 and December 1997, 61 patients with renal calculi underwent percutaneous nepholithotomy. In the immediate postoperative period, 49 renal units (80.3%) were stone-free. At three months, our overall success rate was 91.8% after spontaneous elimination of non-significant residual calculi (< 3 mm). Complications were observed in 9.8% (six cases); hemorrhage and sepsis were the major complications. Percutaneous nephrolithotomy is an effective, safe and reliable alternative to the open operation.
