肾盏憩室临床分析(附30例报告)

Clinical Analysis of Caliceal Diverticulum(A Report of 30 Cases)

目的:分析肾盏憩室静脉尿路造影（IVU）检查的影像特征、鉴别诊断,概括检查技巧。方法:回顾性分析30例肾盏憩室的临床资料、超声及造影检查记录。结果:本组30例共发现憩室34个,13个憩室并发憩室内结石,9个憩室明确显示“中间细管”,2例并发肾重复畸形,1例并发肾肿瘤。憩室多位于一侧肾上极实质内,呈圆形或卵圆形与肾盏借一“中间细管”相连,显影时间常滞后于肾盂肾盏,并有排空延迟现象。结论:静脉肾盂造影和逆行肾盂造影是诊断、鉴别和介入治疗时定位肾盏憩室的主要方法。

Objective: To analyze (he features of intravenous urography( IVU), differential diagnosis of caliceal diver-ticulum and to summarize the skill of examination. Methods: The clinical data and records of B-ultrasound and IVU in 30 patients with caliceal diverticulum were analyzed retrospectively. Results: In the 30 patients, 34 caliceal diverticulums were found,among which 13 were complicated with stone,9 with small channel connecting to calix,2 with multiple deformation and 1 with renal carcinoma. The caliceal diverticulum usually lied in the upper portion of kidney at one side. It was round or oval in shape and connected to calix by small channel. The imaging time of diverticulum often fell behind with that of calix,and its emptying time was postponed. Conclusion: The IVU and retrograde urography are the main methods to diagnose, differentiate and position the caliceal diver-ticulum in intervential treatment.
