Hydronephrosis frequently occurs during pregnancy. The etiology and significance of this phenomenon are not clearly understood. Further, little information regarding changes in the kidneys during pregnancy and early postpartum is available. This study uses real-time ultrasound in order to investigate whether or not there is a relationship between the degree of calyceal dilatation, kidney size, and creatinine clearance value. Two hundred and eighty-six patients, including 175 pregnant and 111 puerperal individuals, were examined. The overall incidence of hydronephrosis was 67% in the pregnant and 39% in the puerperal women. Moderately and severely affected kidneys were significantly larger than the mildly affected and nonaffected kidneys (p < 0.05, p < 0.001). The creatinine clearance value was lower in patients with severe hydronephrosis than in those with mild and moderate hydronephrosis and in the nonaffected patients, albeit with no statistical significance.
肾积水在孕期经常发生。这种现象的病因及意义尚不清楚。此外，关于孕期及产后早期肾脏变化的信息很少。本研究采用实时超声来调查肾盂扩张程度、肾脏大小和肌酐清除率之间是否存在关联。对286例患者进行了检查，其中包括175例孕妇和111例产后女性。孕妇肾积水的总体发生率为67%，产后女性为39%。中度和重度受累的肾脏明显大于轻度受累和未受累的肾脏（p < 0.05，p < 0.001）。重度肾积水患者的肌酐清除率低于轻度和中度肾积水患者及未受累患者，尽管无统计学意义。
