目的 :探讨利尿在体外冲击波碎石中的作用。方法 :在B超定位、低能量ESWL时通过利尿来充盈肾脏集合系统治疗无肾积水的肾结石278例 (347侧 )。结果 :结石粉碎率100% ,一次碎石成功率95 4 %。副作用少 ,无严重并发症。结论 :体外冲击波碎石时辅以利尿法治疗无肾积水的肾结石 ,具有易于观察、碎石率高和并发症少而轻微等优点 Objective: To investigate the role of diuresis in extracorporeal shock wave lithotripsy. Methods: 278 cases (347 sides) of nephrolithiasis without hydronephrosis were treated with diuresis to infuse the renal collecting system during B-location and low-energy ESWL. Results: The rate of stone crushing was 100% and the success rate of primary crushing was 95 4%. Less side effects, no serious complications. Conclusion: Extracorporeal shock wave lithotripsy supplemented with diuretic therapy for renal stones without hydronephrosis has the advantages of easy to observe, high rate of gravel and few complications
