Ureteric Dilatation of Pregnancy, Its Complications and Sequelæ

women dying from various diseases, and they gave figures for the incidence of ureteric dilatation, which varied within wide limits but averaged out at about 40 per cent. The reason for this variation is not far to seek. First, it is not easy to estimate dilatation of a ureter on the post-mortem table, and under such conditions all but very gross degrees of dilatation remain largely a matter of opinion. Secondly, the post-mortem material utilised by many workers included women dying at all stages of gestation, while, as we shall see later, the ureters only commence to dilate during the latter part of pregnancy. The figure of 40 per cent, must therefore lie well short of the true
