MSCTU diagnosis evaluation of urinary system disease(analysis of 40 cases)

Objective:To explore MSCTU (multislice CT urography) technique in the clinical diagnosis of urinary system disease.Methods:40 patients with urinary system disease underwent either CT plain scan and kidney parenchymal phase enhanced scan (delay 80s) or kidney parenchymal phase enhanced scan directly. The delay scan time was determined according to the hydronephrosis degree, patients with no hydronephrosis delayed 10～15min and patients with hydronephrosis delayed 30～120min. The raw data were transferred to workstation to obtain urinary passage image.Results:Among the 40 patients, there were 3 cases of renal cancer, 7 cases of renal pelvis carcinoma, 7 cases of ureteral carcinoma, 5 cases of calculi, 6 cases of inflammation, 11 cases of congenital malformation and 1 case of bladder vagina fistula.33 cases were confirmed by surgery, pathology and 7 cases were proved by clinical findings. The operation findings were in concord with the helical CT to depict the location, shape and size of lesion.Conclusion:MSCTU has the advantages of fast scan speed, big coverage, high image quality and thin scan slice, and it has signifcace in the diagnosis of urinary system disease.
