肾积水的产前诊断及预后分析
- 摘要:
- 目的评价肾积水产前诊断的价值及预后,防止不必要的中止妊娠。方法利用产前超声检查诊断,对244例371侧集合系统分离径>1cm积水胎肾进行随访观察。结果Ⅰ组为可复性肾积水,158例220只肾,积水宽度在1.0~1.99cm,肾实质厚度0.4~0.6cm,大多数胎儿于分娩后1~6个月后肾积水消失,其中25例引产,18例失随访;Ⅱ组为不可复性肾积水,86例151只肾,积水宽度在2.0~5.85cm,肾实质厚度在0.15~0.52cm,其中40例随访至出生后6个月~4年,仍为重度肾积水,6例无变化,31例引产,9例失随访。结论超声检查可较早对胎儿肾积水进行评估,如胎儿肾积水宽<1.5cm或实质厚度>0.5cm可视为可复性肾积水;而积水宽度>2.5cm或肾实质厚度<0.2cm则可能为不可复肾积水,出生后应及时治疗。
