title: [Risk of incompatibility reactions in the repeated use of contrast media in urography].
abstract: In a prospective study 260 urographies were evaluated regarding clinical compatibility. In altogether 11% of the patients mild incompatibility reactions were observed (heat sensation, urticaria, nausea, vomiting). 29% of the patients with known prior contrast agent incompatibility suffered from anaphylactoid symptoms mostly of a subjective type (heat sensation, nausea). There was no statistically significant difference in the frequency of objective symptoms (urticaria, vomiting) between patients with prior contrast media incompatibility (3%) and patients who had tolerated previous contrast media applications without symptoms (2%).
