用国产美芝JT-ESWL-Ⅲ型体外震波碎石机治疗上尿路结石470例,其中肾结石328例(单侧314例,双侧14例),输尿管结石142例(近段94例,远段48例);结石最小0.5×0.7cm,最大3.5×7.0cm。震波为300～3000次,平均1500次。接受一次治疗者377例(80.2％)。二次治疗者85例(18.1％),三次以上者8例(1.7％)。结石完全粉碎及部分粉碎462例(98.3％),未粉碎8例(1.7％)。排石时间一般在震后1～2d开始,排净碎石最快者为震后72h,多数在1～2个月基本排净。作者结合临床实践,对ESWL治疗的病例选择,多发性肾结石及输尿管“石街”形成的处理原则作了较为详尽的讨论。
A total of 470 cases of upper urinary tract stones were treated with domestic MTB-ESWL-Ⅲ extracorporeal shock wave lithotripsy, including 328 cases of kidney stones (314 cases of unilateral, 14 cases of bilateral), 142 cases of ureteral calculi (94 cases, Distal segment 48 cases); the smallest stone 0.5 × 0.7cm, the largest 3.5 × 7.0cm. Shock wave 300 to 3000 times, an average of 1500 times. A total of 377 patients (80.2%) received treatment. 85 cases (18.1%) were secondary treatment, 8 cases (1.7%) more than three times. 462 cases (98.3%) were completely crushed and partially crushed, and 8 cases (1.7%) were not crushed. Paihuan time is generally 1 ~ 2d after the earthquake began, the fastest net discharge of gravel 72h after the earthquake, the majority of 1 to 2 months in the basic row net. The author combined with clinical practice, the treatment of ESWL cases, multiple kidney stones and ureteral “stone street” formed a more detailed discussion of the treatment principles.
