[Percutaneous nephrolithotripsy: experience with one-stage procedure].
From November 1985 through September 1986, 20 cases of upper urinary tract calculi (14 kidney, 7 ureter) were treated by the one-stage procedure percutaneous nephrolithotripsy. Renal and ureteral calculi were successfully removed in all 20 cases (100%). After the procedure, a few small stone fragments remained in 3 cases (the rate of remnant stone : 14%). High fever was noted in 7 patients but did not last longer than 3 days. No patients required blood transfusion. The one-stage percutaneous procedure was considered a more efficient procedure to remove the upper urinary tract calculi, than open surgery or two stage percutaneous nephrolithotripsy. In one-stage percutaneous nephrolithotripsy, however, serum sodium concentration was lowered significantly after the procedure, although the hematocrit remained unchanged throughout. This should be carefully corrected by the supplement of irrigation fluid and intravenous infusion during the procedure.
