体外冲击波碎石术治疗肾感染石137例

目的：观察体外冲击波碎石术治疗肾感染石的疗效。方法：分别采用B超或X线定位的碎石机连续性治疗137例例肾感染石患者。总结定位。碎石效果及并发症发生情况。结果：单次治愈75例（54．74％），2次治愈33例（24．09％），3次治愈15例（10．95％），4次治愈5例（3．65％），5次治愈5例（3．65％），失败4例（2．92％）。术后因尿路感染发热者15例（10．95％），24例（17．52％）并发肾绞痛，17例（12．41％）并发＞5cm的石街，均经对症治疗后治愈。结论：碎石时B超定位方式优于X线定位；只要方法正确，碎石前后控制尿路感染，体外冲击波碎石术是一种安全、有效的治疗肾感染石的方法。

Treatment of 137 patients with renal infection stones by extracorporeal shock wave lithotripsy

Objective:To observe the effect of extracorporeal shock wave lithotripsy (ESWL) for treatment of renal infection stones.Methods:A total of 137 patients with renal infection stones (124 with partial and 13 with complete staghorn calculi) underwent ESWL with lithotriptors using ultrasound or fluoroscopic localization system.There were altogether 192 calculi.Their diameters ranged from 1 4 to 4 7 cm(mean 2 3 cm).Preoperatively,double J ureteral stents were applied to 28 patients with larger calculi and Dormia stents to 8 similar ones.Results:Seventy five cases(54 74%)were cured in one session;33 cases(24 09%),in two sessions;15 cases(10 95%),in three sessions;and in four and five sessions,there were 5 cases each(3 65%,each).4 cases(2 92%)failed in the treatment.15 patients(10 95%)were complicated with fever due to urinary tract infection after ESWL and cured with antibiotics.Steinstrasse occurred in 17 patients (12 41%),which were soon cured by conservative procedures or repeat ESWL. Conclution:Ultrasound was superior to fluoroscopy in stone localization during lithotripsy; ESWL was considered to be a safe and effective treatment of renal infection stones.
