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 the imaging features, differential diagnosis and general inspection technique of calyceal diverticula intravenous urography (IVU). Methods: A retrospective analysis of 30 cases of calyceal diverticulum clinical data, ultrasound and imaging records. Results: 34 cases of diverticulum, 13 diverticulum and diverticula were found in 30 cases of this diverticulum. Nine diverticula showed “middle tubule”, 2 cases had renal deformity and 1 case had renal tumor. Diverticulum mostly located in one side of the kidney very parenchyma, was round or oval and renal calyx by a “middle thin tube” connected, the development time lag often in the renal pelvis, and emptying delay phenomenon. Conclusion: Intravenous pyelography and retrograde pyelography are the main methods to locate calyceal diverticulum during diagnosis, differential diagnosis and interventional therapy.
