32例肾囊肿的X线和B超分析

Radiologic and B-mode Ultrasonographic Analyses of 32 Cases of Renal Cysts

对３２例肾囊肿做了Ｘ线和Ｂ超分析．显示尿路平片可见肾外形的改变，静脉尿路造影表现出肾盂、肾盏移位、变形的各种形态．并探讨了其形成的机理．通过Ｘ线检查７例肾囊肿误为正常或肾癌，分析造成误诊的原因。Ｂ超检查显示边界清楚的圆形或椭圆形无回声液性暗区，其中仅１例将肾囊肿误诊为肾积水，诊断符合率为９７％（３１／３２）．因此，临床上颖有肾囊肿的影象检查应首选Ｂ超检查，Ｘ线检查能显示肾解剖结构和轮廓，提高对本病的诊断率，并讨论了ＣＴ对肾囊肿诊断的价值。

This paper reported the results of radiologic and B-mode ultrtasonographic analyses of 32 patients withrenal cysts, The change of renal shape was demonstrated on X-ray plainfilm. The manifestations of renal cystof IVU were shown with various degree of displacement and deformity of renal pelvis and calyces. Its mecha-nism of production was evaluated. Seven cases of renal cysts were erroneously diagnosed as normal or renalcarcinoma in radiologic studies. The causes, of misdiagnosis were discussed,B-mode ultrasonography shows around or oval anechoic liquiform dark region with definite margin. Only one case on ultrasonography was mis-diagnosed as hydronephrosis, In this series,the diagnostic accuracy rate of ultrasound was 97%(31/32),so it shoud be the first choice of modalities for the clinically suspected patients.X-ray examination can demon-strate the contour and structure of the kidney clearly.so it can elevate the diagnostic accuracy.The value ofCT in dingnosis of renal cyst was discussed.
