Extracorporeal shock wave lithotripsy for upper urinary tract stones using the Dornier Lithotripter Compact: an experience in Japan

Abstract

1997年5月～1998年2月の間に腎結石40例, 尿管結石40例(男性60例, 女性20例)についてドルニエリソトリプターコンパクトを用いた治療を行った.結石のサイズは5～80mmであった.大多数の症例は無麻酔で行ったが, 3例に硬膜外麻酔を必要とした.また4例に尿管ステント留置後に治療を行った.全ての症例において結石砕石は認められた.1ヵ月後の評価では砕石効果と完全排石率は91%と54%, 又, 3ヵ月後の評価では砕石効果と完全排石率は91%と68%であった.腎盂腎炎や腎周囲血腫, 大量の血尿等の重篤な副作用はみられなかった.ドルニエリソトリプターコンパクトは腎尿管結石の治療において安全で砕石効果が優れていると考えられた

Between May 1997 and February 1998, 40 cases of renal stones and 40 cases of ureteral stones in 60 males and 20 females were treated with the Dornier Lithotripter Compact. The size of the stones ranged from 5 mm to 80 mm. Three patients required epidural anesthesia and 4 patients required a ureteral stent. Fragmentation of the stones was observed in all patients. After 1 month, the efficacy and stone free rates were 91% and 54%, respectively. After 3 months, they were 91% and 68%, respectively. There were no serious side effects such as pyelonephritis, perirenal hematomas, and massive hematuria. In conclusion, the Dornier Lithotripter Compact proved to be a safe and highly effective lithotripter for the treatment of renal and ureteral stones.
