第三世代ESWL装置Therasonicによる尿路結石の治療経験

Abstract

1)1992年7月までの14ヵ月間に, 115例の上部尿路結石に対しTherasonicによる破砕治療を行った。2)術後1ヵ月目の観察で, 腎盂腎杯内54結石中48結石, 腎盂尿管移行部8結石中7結石, 上部尿管30結石中27結石, 下部尿管結石23例全例で完全排石をえた。3)2例に腎周囲血腫を認めたが, 保存的療法で軽快した。他の症例には重篤な合併症は見られなかった

A third generation lithotripter (THERASONIC Lithotripsy Treatment System) was used for disintegration of upper urinary tract calculi. A total of 115 patients was treated at Miki Municipal Hospital, 54 with renal calculi, 8 with UPJ calculi, 30 with upper and 23 with lower ureter calculi. The stone-free rate one month after treatment was 89%, 88%, 90% and 100% for renal, UPJ, upper ureter and lower ureter calculi, respectively. As for side effects, we experienced two cases of perinephric hematoma which were treated conservatively. However, we encountered no other severe complications. These findings clearly indicated that the THERASONIC lithotripter is highly useful for disintegration of calculi of the upper urinary tract.
