Dilatation of the Ureters and Renal Pelves in Pregnancy

Abstract

In pregnancy, there is a constant right-sided ureteral dilatation; while right hydronephrosis is only slightly less frequent. In pregnancy, the left ureter and renal pelvis escape this dilation in a markedly higher % of cases. Bilateral hydroureter and hydronephrosis were of very frequent occurrence. The multiparous woman showed these conditions earlier, more frequently, and in much more marked degree than the primipara. Stasis, as measured by the inability of the renal pelvis and ureter to empty themselves within normal time limits, is a definite and almost universal finding in the antepartum woman. In the postpartum woman it is persistent, in a lesser degree, over a prolonged period. Every pregnant woman has obstruction of some degree, a definite dilatation of the ureters and renal pelves, with a well defined stasis. This continues a long time. In the apparently healthy pregnant and puerperal patient a probable renal complication in the presence of pus and coliform organisms is demonstrated.
