[Sonographic studies of physiologic involution of the uterus in the puerperium].

141 sonographic investigations were performed in a group of 52 patients between the first and eighth day after normal delivery for supervision of physiologic involution of the uterus. There were examined position of the uterus, size of cervix and corpus and thickness of anterior and posterior uterine wall. The results were examined statistically concerning correlations to birth weight of the newborn.
