Urography and renography in the follow-up of patients with toxemia of late pregnancy.

Abstract

We have studied 129 patients with toxemia of pregnancy two months post partum by urography and renography. The same investigations were performed on 17 healthy parturients post partum. 49 patients (38.8%) had an abnormality either in urography or renography. 20 patients (15.5%) had an abnormal urogram and 42 (32.6%) an abnormal renogram. The findings correlated so that 7 patients had an abnormal urogram with a normal renogram and 13 patients had an abnormality in both investigations. 29 patients had only an abnormal renogram. In the control series 3 patients had an abnormal urogram and the same patients also had an abnormal renogram. We divided the studied patients into groups according to the clinical severity of toxemia. Urographic and renographic findings were divided evenly in the series so that abnormalities were no more common in the severe cases. Renography cannot be considered merely as a screening method when compared with urography in the follow-up of toxemic patients, but these investigations are complementary.
