[Can fetal kidney dilatation be physiologic?].
Sonography was used to detect and to measure the foetal calyceal system in more than 100 cases of pregnancies ranging from the 25th week to term. In 13.6% of the investigated cases physiological dilatations can be demonstrated. There is no connection with the volume of the foetal bladder or with the extension of the maternal calyceal system. The observed dilatations disappear spontaneously post partum. References to pathological dilatation of the foetal calyceal system are discussed.
