[Perirenal extravasation of contrast media during urography]
Abstract:
The authors report on 28 cases of contrast medium extravasates during urography. Own results and those obtained by other authors in respect of clinical findings, diagnosis and therapy are discussed. Our experiences have shown that an aggressive diagnostic or therapeutic approach is not indicated, since the sequels of these extravasates have no special clinical importance. As a rule, treatment is unnecessary, especially inpatient observation. Hence, our experiences confirm the trend to proceed as conservatively as possible.
