The Smallest Amount of Contrast Media Possible Use for Intravenous Urography at Sisaket Hospital

Abstract

Objective: To study the smallest amount of contrast media use for intravenous urography and adverse reactions.
Study design: Descriptive, retrospective study.
Setting: Department of Radiology, Sisaket hospital.
Subject: The intravenous urographic assessment questionnaire of 503 patients, who were sent for intravenous urographic examination in Department of Radiology of Sisaket hospital from October 2004 to September 2005.
Result: Five hundred and three patients who were sent for intravenous urography, 257 male and 246 female. The age range is between 3 months to 89 years. Most of patients had serum creatinine level less than 2 mg%. The retrospective review of the contrast dosage revealed 44 patients received intravenously contrast volume more than the dosage calculated based on body weight had 4.54% of adverse reactions and 346 patients received intravenously contrast volume less than the dosage calculated based on body weight had 3.76% of adverse reactions. The patient's body weight less than 60 kg used contrast volume 1-15 ml. less than body weight, body weight more than 60 kg. used contrast volume 16-35 ml. less than the body weight.
Conclusion: In normal renal function patient, the contrast volume less than 1 ml./kg. is appropriate volume, decreased cost and less adverse reaction.
Key words: intravenous urography, contrast reaction
