先天性巨输尿管症的X线及CT诊断

目的:探讨X线与CT对先天性巨输尿管症的诊断价值。方法:总结分析了17例经病理证实的先天性巨输尿管症静脉泌尿系造影及CT的影像资料。17例患者均进行了尿路造影,11例患者行CT检查。结果:本症以输尿管近膀胱一段短于2cm保持正常管径的功能性梗阻段,其上输尿管呈渐进性扩张,部分可延及肾盂肾盏。实时观察时,可见扩张输尿管蠕动频率减慢、幅度增大、向下传递间断。CT证实功能性梗阻段输尿管管壁及管径正常。结论:静脉泌尿系造影为本病主要诊断方法,CT为必要的辅助检查方法。

X-ray and CT Diagnosis of Congenital Megaureter

Objective To reseach the value of X-ray and Computed Tomography(CT)in Congenital Megaureter.Methods The radilogical urography and CT findings of 17 Congenital Megaureter cases confirmed by operation were summarized and analysed.In 17 patients,all of them had the radilogical urography examination,11 cases had CT scan.Results In this disease,less than 2 cm ureter segment of near bladder was normal in calibre and was a functionality obstructed segment,the ureter segment above it was gradually dilatation,thr part could spread to renal pelvis and renal calices.Observing on the real time,the frequency of peristalis of dilatate ureter reduced slow,transfer was interrupted.CT confirmed the functionality obstructed segment was normal in tube wall and calibre.Conclusion The radilogical urography is the best way to Diagnose the Congenital Megaureter,the CT scan is a method for the necessary assistance.
