目的 :探讨体外冲击波碎石术前静脉尿路造影检查的临床应用。方法 :对 436例尿路结石患者采用常规法、延时法、大剂量法、利尿法等方法进行静脉尿路造影检查。结果 :436例患者中 42 1例患者明确了结石部位、尿路梗阻情况、肾积水程度和尿流出路情况 ,给体外冲击波碎石术提供了依据并取得满意碎石效果。结论 :静脉尿路造影检查仍是目前体外冲击波碎石术前的必查项目之一 ,但不必拘泥于教科书上常规检查方法 ,应根据尿路显影情况 ,灵活多变 ,以满足体外冲击波碎石术的特殊要求
Objective: To investigate the clinical application of extracorporeal shock wave lithography preoperative intravenous urography. Methods: 436 patients with urolithiasis were examined by venous urography using conventional method, delayed method, high dose method, diuretic method and so on. Results: Forty one hundred and thirteen patients (431) were confirmed with stone site, urinary tract obstruction, hydronephrosis and urinary excretion, which provided the basis for extracorporeal shock wave lithotripsy and achieved satisfactory gravel effect. Conclusions: Intravenous urography is still one of the necessary items before CEEP. However, it is not necessary to stick to the routine examination method in textbooks. It should be flexible according to the development of urinary tract to meet the requirements of extracorporeal shock wave lithotripsy Special requirements of surgery
