1984年7月より1年6ヵ月の間に20症例に対して経皮的腎切石術を施行した.20例中17例において結石の摘出に成功した.この17例中14例においては残石を認めなかった.他の3例においては小残石を認めた.合併症は重大なものを4例中, 軽度なものを9例に認めた.全例において輸血を必要としなかった

Between July, 1984 and January, 1986, 20 cases of renal and ureteral stones were treated by percutaneous nephrolithotomy (PNL). Stone removal was successful in 17 cases (85%). In 14 cases, stones were removed completely and in 3 cases there were small residual fragments. There were 4 major and 9 minor complications. The major complications consisted of loss of tract in 2 cases, bleeding from the tract after removal of nephrostomy catheter in 1 case and pneumothorax in 1 case. The minor complications consisted of small perforation during PNL in 6 cases, gross hematuria impossible to continue PNL in 2 cases and ureteral injury due to ureteral occlusion catheter in 1 case. No patients required blood transfusion. In near future all urologists will be required to master the technique of PNL.
