Response of patients to informed consent for excretory urography.

The desirability of obtaining written informed consent for low-risk radiologic procedures has been the subject of controversy. A group of 80 patients was studied to evaluate the effect of informed consent for excretory urograms on: (1) incidence of contrast reactions; (2) discomfort during the procedure; (3) level of patients' anxiety before and after the procedure; (4) patients' perception of the procedure; and (5) desirability of informed consent from the patients' viewpoint. Results revealed no statistically significant difference between the 2 groups in the incidence of reactions, discomfort, perception of the examination, or anxiety level prior to the procedure.

Comparative study of the sodium salts of iodamide and iothalamate in clinical urography.

In a comparative urographic study of the sodium salts of iodamide (Uromiro 300 Sodium) and iothalamate (Conray 420) the following conclusions have been made. (i) In subjects with radiologically normal kidneys and a creatinine clearance greater than 70 ml/min, nephrogram scores were significantly higher with iodamide (P less than 0.02).
