経皮的尿管結石摘出術と尿管切石術の比較

COMPARISON OF PERCUTANEOUS URETEROLITHOTOMY VERSUS OPEN URETEROLITHOTOMY

　1986年9月までの18ヵ月間に施行した経皮的尿管結石摘出術27例（PNL群）と尿管切石術16例（尿管切石術群）について，術中出血量，手術時間，術後経過，入院費，合併症を比較した，手術時間，術後経過，入院費に関しては，両群に有意な差はなかつたが，PNL群では出血量が多く（p＜0.01），合併症も多様であつた。したがつて，PNLは尿管切石術よりも侵襲の少ない治療法とは言えなかつた。しかし，開腹手術の既往がある症例や腎結石を合併している症例では，PNLは有力な治療法であり，また術創が小さいことも魅力的であつた。

From April 1985 to September 1986, 27 cases were treated by percutaneous ureterolithotomy (PNL group) and 16 cases by open ureterolithotomy (Lithotomy group). In regard to the operation time, the number of cases without postoperative analgesics, the postoperative hospital stay, and the total cost of admission, there were no significant differences between PNL group and Lithotomy group. The amount of the intraoperative blood loss averaged 774 ml in PNL group, and 92 grams in Lithotomy group (p <0. 01), although no blood transfusion was required in both groups.
