目的 :探讨体外震波碎石 (ESWL)治疗肾结石的有效性。方法 :应用上海HX 90 2碎石机治疗 1 2 6例肾结石 (直径为 0 5～ 2 .5cm)住院病人 ;部分病人在碎石前插入双 J管。结果 :结石直径在≤ 0 8,0 9～ 1 9,≥ 2cm ,其二月内的排出率分别为 53 3 % ,40 8% ,1 8 1 % ;总排出率为 45 6 %。并发症少见 ,1例肾包膜下血肿 ,采用保守治疗 ;1 5例肾绞痛及 5例“石街”形成 ,采用输尿管镜、再次碎石或保守治疗 ,结石完全排出。结论 :ESWL是治疗肾结石 (直径 <2cm)的有效方法。对大于 2cm的结石 ,应首先行开放手术或经皮肾镜碎石 (PCNL)治疗
Objective: To investigate the effectiveness of extracorporeal shock wave lithotripsy (ESWL) in the treatment of kidney stones. Methods: One hundred and sixty - six inpatients with kidney stones (diameter of 0.5 ~ 2.5cm) were treated with Shanghai HX 90 2 lithotripsy machine. Some patients were inserted with double J tube before the gravel. Results: The diameter of stones was ≤ 0 8, 0 9 ~ 1 9, ≥ 2 cm. The discharge rates in February were 53 3%, 40 8% and 181%, respectively. The total discharge rate was 45 6%. Complications were rare, 1 case of subrenal hematoma, conservative treatment; 15 cases of renal colic and 5 cases of “stone street” formed by ureteroscopy, again gravel or conservative treatment, stones completely discharged. Conclusion: ESWL is an effective treatment for kidney stones (diameter <2cm). For more than 2cm of stones, should be the first open surgery or percutaneous nephrolithotomy (PCNL) treatment
