CR静脉肾盂造影在体外碎石中的临床价值

目的探讨计算机x线摄影（CR）静脉肾盂造影在体外碎石中的临床价值。方法回顾性分析71例行体外碎石治疗的泌尿系结石患者静脉肾盂造影影像资料，碎石前造影51例，碎石同时造影20例。结果71例患者中62例肾功能良好，9例肾功能受损。结石≤1．5cm的65例，一次击碎64例（98．46％），一次排净率为56例（86．15%）；〉1．5cm者6例，均经两次或两次以上碎石方能排净。结论CR静脉肾盂造影能准确定位泌尿系结石，同时能准确反映肾功能，有利于泌尿系结石患者体外碎石治疗。

Clinical value of computed radiography intravenous pyelography in extracorporeal shork wave lithotripsy

Objective To evaluate the clinical value of computed radiography （CR） intravenous pyelography in extracorporeal shork wave lithotripsy （ESWL）. Methods The intravenous pyelography in 71 patients with urinary tract calculus were analyzed retrospectively. Fifty one cases underwent intravenous pyelography before lithotripsy and 20 cases at the time of lithotripsy. Results Among 71 patients, renal function was normal in 62 and renal failure was revealed in 9. The calculus （≤1.5 era） in 64 patients among 65 patients （98.46%） were stroke to pieces and in 56 patients （86. 15%） were eliminate one time. The calculus （〉1.5 cm） in all 6 patients were stroke to pieces and eliminate twice or more than twice, resulting a 97.18% successful rate of ESWL. Conclusion The calculus can be located and renal function can evaluated accurately by CR intravenous pyelography. CR intravenous pyelography is very helpful in extracorporeal shock wave lithotripsy.
