The application value of multislice CT in diagnosis of ureteral biology variation and diseases

Objective To discuss the application value of multislice CT (MSCT) in diagnosis of ureteral biology variation and diseases.Methods The MSCT data of 51 patients with suspected ureteral biology variation and diseases were retrospectively analyzed.The data of MSCT images included plain scan,renal cortical phase,renal parenchyma phase and excretion phase.The MSCT images of renal cortical phase,renal parenchyma phase and excretion phase were reconstructed respectively to gain the 3D images of renal arteries,veins and urinary passage.Results Among the 51 patients,1 patient with traumatic ureteral rupture,10 patients with ureteral biology variation diseases,14 patients with stone of ureter,2 patients with polyp of ureter,3 patients with non-specificity ureteritis,3 patients with tuberculosis of ureter,1 patient with endometriosis,17 patients with carcinoma of ureter.Satisfied 3D images of renal arteries,veins and urinary passage could be reconstructed.And the imaging diagnosis of 51 patients were all in accord with their clinical diagnosis or pathologic diagnosis.Conclusion MSCT can obtain high qualified images,and this technique should become the preferred inspection item of ureteral biology variation and diseases.
