Method:Children with congenital urinary system anomaly in 40 cases with pathologically confirmed duplicat ion of kidney were performed routine urinary system ultrasonography, IVP and CT scan following IVP within one week before surgery, CT images postprocessing by curved planar reformation (CPR)，multiplanar reformation (MPR)，the maximum intensity projection (MIP) ， volume rendering technique (VRT) methods. We compared the diagnostic accuracy and the value of typing of duplex kidney amone three imaging methods. Result:Thirty-one cases were diagnosed by ultrasound, the diagnostic accuracy rate was 77. 5%;26 cases were diagnosed by IVP examination, the diagnostic accuracy rate was 65. 0%;38 cases were diagnosed by CT following IVP combined with IVP, the diagnostic accuracy rate was95. 0%.
