OBJECTIVE To evaluate the frequency of adverse events and possible risk factors after the administration of an intravenous contrast medium (CM), iobitridol, in a large multicentre postmarketing surveillance study. SUBJECTS AND METHODS A total of 49,975 patients undergoing intravenous urography were included in this study. A water-soluble, non-ionic CM (iobitridol, 1 ml/kg body weight) was adm...

results the diagnostic value of ivu was found positive in 6.5% while it was negative in (93.5%) cases. the sensitivity and specificity of usg, rad and their combination in detection of urolithiasis was calculated as 90.5% and 84.8%, 84.1% and 88.6%; and 98.4% and 4.8% respectively. conclusions ivu can be largely replaced by usg in the pediatric population and if really clinically needed, its in...

OBJECTIVE The purpose of this study was to compare the cost-effectiveness of sonography and CT for the evaluation of renal masses discovered at excretory urography. MATERIALS AND METHODS The records of 225 patients with a renal mass shown by urography who then had either sonography or CT within 3 months were reviewed retrospectively. The number, location, and size of lesions; initial and subs...

Diuresis renography is helpful when the funct...
