Serum creatinine measurements: evaluation of a questionnaire according to the ESUR guidelines:

BackgroundThe European Society of Urogenital Radiology (ESUR) propose measurements of serum creatinine levels in patients undergoing contrast-enhanced studies with a high probability of impaired renal functionand therefore with a higher risk of CIN and NSF.PurposeTo determine whether the recommended questionnaireis able to select these patients.Material and MethodsOver a time period of 10 months the questionnairewas conducted in 1389 patients (725 women, 654 men) before contrast administration for computed tomography (CT) or magnetic resonance imaging (MRI) examination. Serum creatinine (SCr) measurements and calculation of estimated glomerular filtration rate (eGFR) values were performed when one or more answers were positive. Eighty-one patients were excluded due to incomplete data. Statistical evaluation of the questionnairewas done retrospectively.ResultsFour hundred and ninety-ninepatients (38%) gave one or more positive answers to the questionnaire. Of these, 71 (14%) had an eGFR <60 mL/min/1.7...
