Thirty-one patients with anomalous and/or pathological conditions in the duplication of the renal pelvis and ureter were studied in order to analyze the urographic findings. A segmental defect evident in the visualization was caused by the abscess of one of the poles in the kidney. In patients with hypoplasia of one of the poles, the other normal pelvis extended to the neighboring segment, and consequently showed the same pattern as a simple pelvis and ureter on urography. The renal hypoplasia was apt to be combined with simple or ectopic ureterocele and ectopic ureteral opening. In patients with non-visualization of two pelves, hydronephrosis or renal hypoplasia was proved by other radiological modalities including computed tomography. Incidence of vesicoureteral reflux was more frequent in the ureter of the lower pelvis. Reflux was also found between the two ureters of the bifid ureter. It was concluded that these urographical findings correlated closely with pathological conditions.
为分析肾盂和输尿管重复畸形及/或病理状况的尿路造影表现，对31例患者进行了研究。造影显示的节段性缺损是由肾一极的脓肿所致。在一极发育不全的患者中，另一正常肾盂延伸至相邻节段，因此在尿路造影上显示出与单纯肾盂和输尿管相同的形态。肾发育不全易合并单纯或异位输尿管囊肿及异位输尿管开口。在两肾盂均不显影的患者中，通过计算机断层扫描等其他放射学检查证实存在肾积水或肾发育不全。下肾盂输尿管的膀胱输尿管反流发生率更高。在双输尿管的两条输尿管之间也发现了反流。结论是这些尿路造影表现与病理状况密切相关。
