Clinical application of 64-slice spiral CT three-dimensional reconstruction of urinary tract in ureteral lesions

Objective To investigate diagnostic value of the 64-slice spiral CT in the cause of ureteral lesions.Methods Ninety-eight cases of patients with ureteral lesions scan by 64-slice spiral CT urography(computed tomography urography,CTU),using volume rendering(VR),maximum intensity projection(MIP),curved planar reformation(CPR) and other post-processing techniques were observed,and comparative analyed with surgery or pathologic results.Results Among seventy-six cases of adult patients with ureteral lesions,there were 32 cases of ureteral calculi,20 cases of ureteral cancer,5 cases of violations of the ureter in bladder cancer,19 cases of obstruction by external pressure,in which 3 cases of retroperitoneal fibrosis,8 cases of internal iliac arteriovenous malformation,8 cases of pseudoaneurysm;22 cases of child patients with ureteral lesions,9 cases for the department of ureteropelvic transitional narrow,7 cases of lower ureteral stenosis,and 6 cases of ureteral duplication of renal duplication.Conclusion 64-slice spiral CT three-dimensional reconstruction contributes to the application of qualitative diagnosis in ureteral lesions.
