Thirty-one fetuses with hydronephrosis and 14 fetuses with spinal dysraphism were sonographically examined. In only one instance was spinal dysraphism associated with hydronephrosis. This single case was identified in a term pregnancy. There was no statistically significant association of urinary tract dilation and open spinal defects in utero. This observation tends to confirm the reports that urinary tract dilatation associated with spinal dysraphism is less frequent when neonates and children are compared. the progressive decrease in this association appears to extend to the fetal period.
对31例肾积水胎儿和14例脊柱裂胎儿进行了超声检查。仅1例脊柱裂合并肾积水。该例为足月妊娠。宫内尿路扩张与开放性脊柱裂之间无统计学意义上的关联。这一观察结果倾向于证实以下报道，即与新生儿和儿童相比，脊柱裂合并尿路扩张的情况较少见。这种关联的逐渐减少似乎延伸至胎儿期。
