Low-dose low-osmolar urography with iohexol.

OBJECTIVES

To study the diagnostic efficacy of low-dose iohexol (90 mg iodine/kg body weight) for intravenous urography.

MATERIALS AND METHODS

Intravenous urography was performed using low-dose iohexol in 50 patients with various urinary complaints. Patients with elevated blood urea and serum creatinine levels were excluded. The urographic films were evaluated with regard to diagnostic information about renal parenchyma, calyces, collecting system and overall image. Patients were also observed for adverse reactions.

RESULTS

A satisfactory diagnosis could be reached in 94% of patients with low-dose iohexol. Only a minor reaction in the form of heat sensation was noted in 1 patient, which did not require any treatment.

CONCLUSION

Iohexol is safe and very useful diagnostically in a low dose for routine intravenous urography.
