静脉肾盂造影联合逆行肾盂造影诊断肾盂输尿管移行处狭窄120例分析

Analysis of 120 cases of joint diagnosis in ureteropelvic junction obstruction with intravenous pyelography and retrograde pyelography

目的:探讨静脉肾盂造影联合逆行肾盂造影诊断肾盂输尿管移行处狭窄上的诊断价值。方法:回顾性分析120例经手术证实的肾盂输尿管移行处狭窄患者术前的静脉肾盂造影及逆行肾盂造影的影像学表现。结果:85例单行静脉肾盂造影可清晰显示狭窄段输尿管并见造影剂间断通过狭窄段;35例并行逆行肾盂造影后显示狭窄段长度及其下方输尿管情况;120例中87例肾脏显影延迟。患者均行开放手术或腹腔镜确诊。结论:静脉肾盂造影联合逆行肾盂造影能明确诊断肾盂输尿管移行处狭窄,并能良好的显示肾脏排泄功能及UPJ狭窄部位及程度,亦可显示肾盂、输尿管继发性改变。

Objective： To explore the value of joint diagnosis of ureteropelvic junction obstruction with intravenous pyelography and retrograde pyelography. Methods： Retrospective analyzed of preoperative intravenous pyelography and retrograde pyelography findings of 120 cases diagnosed with ureteropelvic junction obstruction in surgery were performed. Results： 85 cases of separate intravenous urography could clearly showed the narrow ureter and the interrupted passage of the contrast agent in the narrow section; 35 cases of parallel retrograde pyelography showed after the length of the obstructed ureter and the condition of the part followed the obstructed; and among the 120 cases, 87 cases showed delayed renal imaging. All the cases were confirmed with open or laparoscopic surgery. Conclusion： Intravenous pyelography combined with retrograde pyelography can confirm the diagnosis of ureteropelvic junction obstruction, display renal excretory function and the degree and location of ureteropelvic junction obstruction, and also show the secondary change of renal pelvis and ureter.
