GD-DTPA IN MALE URETHROGRAPHY - A CASE-REPORT

Patients with a case history of severe side-effects from iodine-contai ning contrast media present problems in later radiological examination . We report here on an alternative, the first extravascular use of Gd- DTPA in an X-ray urethrography. By using the standard processing algor ithm of our digital radiographic equipment and 60 mi undiluted Gd-DTPA meglumine (469 mg/ml) we achieved good contrast and could exclude the suspected urethral diverticulum in a 26-year-old man. No adverse reac tions occurred. Gd-DTPA seems to offer a reasonable contrast and may b e used as an alternative extravascular contrast medium in selected con ventional radiographic studies.
