From 1978 to 1981, we have performed peridurography in ninety-six cases.
In this study, we compared its finding with myelographical and surgical findings.
Of ninety-six cases, fifty six were intervertebral disc herniation, sixteen were lumbar canal stenosis, fourteen were lumbar spondylolisthesis, five were lumbar pseudolisthesis, two were caudal tumor and one was lumbar degenerative arthritis.
The findings of peridurography correlated to clinical and surgical findings as well as myelography.
In peridurography, root findings are quite valuable. In the case the myelography shows block lesion, we consider that peridurography should be performed to clarify the root and caudal lesion which cannot detect by conventional myelogram.
We concluded that peridurography is one of the most useful and convenient method in the diagnosis of low back lesion.
