正常妊娠常伴有输尿管和肾盂的扩张,为确定这种扩张是否为生理性(输尿管平滑肌松弛所致)或解剖性(胎儿压迫输尿管所致,尤是右侧,因其在骨盆缘跨过髂动脉)进行了大量研究。但目前尚无资料能帮助临床医生认识正常妊娠期间泌尿道扩张的程度,而难以了解扩张至何种程度才是疾病过程。以下介绍一例妊娠合并泌尿道高度扩张病例。 Normal pregnancy is often accompanied by dilatation of the ureter and the renal pelvis. In order to determine if this dilation is physiologic (due to relaxation of the smooth muscle of the ureter) or anatomical (due to the oppression of the ureter by the fetus, especially to the right, Artery) conducted a lot of research. However, there is currently no information to help clinicians understand the extent of urinary dilatation during normal pregnancy, and it is difficult to understand to what extent the expansion is the disease process. The following describes a case of pregnancy with severe cases of urinary tract dilatation.
