[Nephrosonography--findings in acute pyelonephritis gravidarum]

Nephrosonographic checks were made on 25 women during pregnancy (prior to and after treatment) and after childbirth, in order to obtain morphological information on dynamics of upper urinary tract in cases of acute pyelonephritis gravidarum. Pyelectasia was recorded from 19 patients (76 per cent) on the right side, one patient (four per cent) on the left, two patients (eight per cent) on either side, and was not recorded at all from three women (twelve per cent). Moderate to severe dilatations had been more often recordable from patients with high temperature, but not as often from mild cases. Recurrence rates went up along with severity of ectasia. Physical treatment (lateral positioning and heat) yielded subjectively perceived improvement but failed to result in nephrosonographically recordable decline in dilatation. Pregnancies ended in premature births in 20 per cent of these cases. No dilatation of upper urinary tract was any detectable three months after parturition. While nephrosonography for routine still is disputed in the context of normal pregnancy, it should be used on all cases of acute pyelonephritis gravidarum.
