title: ["Prophylactic" calcium administration in excretory urography in infants (author's transl)].
abstract: The technical approach to excretory urography in the first year of life - especially in small babies - is described. Rare incidents and the clinical toleration are discussed. More than 50% of babies had dyspeptic disturbances following excretory urography. In a previous investigation considerable metabolic changes were found immediately after injection of the contrast medium. Reduction of the calcium blood level seems to be most important. Occasionally convulsions may be induced. 3 ccm/kg body weight of a methylglucaminate is used generally with good toleration (Urovist-Schering). In this investigation 10 babies received 3 ccm Calcium-Sandoz just before the injection of the contrast medium. This prevented hypocalcemia but other electrolytes, for instance potassium had a similar blood level trop as in the control group. Potassium-magnesium-aspartat remained ineffective. Prevention of incidents in babies were reviewed. One possibility could be premedication of calciu. Addition of electrolyte solution (an industrial product) to the contrast medium in children under the age of one year seems to give further improvement. More investigations are necessary.
