自1987年三月起迄1990年二月底為止三年間，台大醫院泌尿科藉體外震波碎石術共治療2039位病人；其中1542位(75.6％)備有完全的資料可據以分析，本研究乃針對這些病人進行回溯性探討。男性病人有1074位，女性468位。年齡分佈由18歲到76歲(平均47.2歲)。平均追蹤時間為13.4個月(範圍：6─32個月)。吾人定義一成功之尿石治療為”完全除去結石或廓清90％以上之結石負荷，並且沒有尿路阻塞”。準此，本系列之整體治療成功率為87.7％。其中腎結石為86.6％，經移位手續之輸尿管結石為97.4％，滯留原位之輸尿管結石上段為82.4％，中段為80.0％，下段則為90.2％。平均住院期間為3.23日(範圍：3─24日)。74位病人(4.8％)必須再度位院接受二度震波或輔助療法。本系列並未發生嚴重的術後併發症，諸如失血性休克或死亡。

A retrospective study was done in 2039 patients who received extracorporeal shock wave lithotripsy (ESWL) at the National Taiwan University Hospital between March 1987 and February 1990. Complete data were available for analysis in 1542 patients (75.6%). There were 1074 men and 468 women. The ages ranged from 18 to 76 years (mean 47.2 years). Mean followup interval was 13.4 months(range: 6-32 months). The success rate, a successful ESWL treatment is defined as being free of stone or diminishing over 90% of the stone burden without obstruction, was 87.7% in the whole series, and was: 86.6% for renal stones, 97.4% (manipulated) and 82.4% (in situ) for upper ureteral stones, 80.0% for middle ureteral stones, and 90.2% for lower ureteral stones respectively. Average hospital stay was 3.23 days(range: 3-24 days). Rehospitaliization was necessary in 74 patients (4.8%). Perioperational major complica-tions, such as hypovolemic shock or mortality, were not encountered in this series. (J Urol R.O.C., 2:387-391, 1991)
