oa South African Medical Journal - Excretory urography in the young subject : hyaluronidase and tomography as aids
Excretory urography in the infam and young child is usually rendered difficult and of lessened value because of (a) the necessity to administer the drug intravenously, and (b) the presence of intestinal gas. The former difficulty may be overcome by the addition of hyaluronidase to the contrast medium which is then injected intramuscularly. The resulting pyelograms have been found to equal those obtained by the intravenous route. The second difficulty may be met by tomography, suitably adapted for use on the young subject.
