ABSTRACT

ObjectiveTo investigate the value of 64-slice CT urography (CTU) in diagnosis of urologic diseases.Methods Sixty patients with suspected urinary system diseases underwent 64-slice CT volume scanning and 3D reconstructions.The diagnostic value of 64-slice CTU was evaluated.ResultsThere were 14 patients with urinary system cancers,2 with ureter polyp,9 with tuberculosis of urinary system,13 with urinary system calculus,13 with nonmalignant ureterostenosis combined with hydronephrosis,2 with ureterostenosis and hydronephrosis induced by nearby organic damage,2 with traumatism,1 with renal occlusion,as well as 4 after urinary tract surgeries and 2 without abnormality.Totally 28 cases was confirmed with surgery and pathology,the sensitivity,specificity and accuracy of MSCTU for upper tract tumor was 100％(14/14),85.71％ (12/14) and 92.86％ (26/28),respectively.ConclusionMSCTU is able to directly and clearly show urologic diseases.It can be regarded as the first choice in patients with clinically suspected urinary tract diseases,especially tumors.
