An absolute contraindication for IVP is -: (A) Allergy to the drug, (B) Multiple myeloma, (C) Blood urea > 200 mg, (D) Renal tumor
Answer is A. • Although IVU gives excellent images of the urinary tract, its use should be restricted because in a few patients the iodine in the contrast medium may provoke a potentially life-threatening anaphylactic reaction.
• Patients with a history of allergy, atopy and eczema are particularly vulnerable, but severe reactions may occur without warning.
