We evaluated normal uterine involution prospectively with real-time ultrasonography in 100 women after uncomplicated term vaginal delivery. Transducers easily distorted the spongy uterus during early postpartum scanning, an effect minimized with sector transducers that are superior to linear or convex probes for accurate early postpartum uterine measurement. Long-axis measurements correcting for uterine angulation were the most reproducible and accurate, irrespective of bladder distention. Uterine contractions caused instability of particularly the transverse dimension. Increasing maternal parity was associated with slightly but significantly larger uterine dimensions up to 4 weeks post partum. The uterus reassumed nongravid dimensions by 6 to 8 postpartum weeks. Uterine involution was unrelated to infant birth weight or breast feeding.
我们采用实时超声检查对100例足月顺产且无并发症的女性进行了正常子宫复旧的前瞻性评估。在产后早期扫描时，换能器很容易使质地柔软的子宫变形，而扇形换能器能将这种影响降至最低，在产后早期子宫精确测量方面，扇形换能器优于线阵或凸阵探头。校正子宫角度后的长轴测量最为可重复且准确，与膀胱充盈情况无关。子宫收缩尤其会导致横径不稳定。产妇胎次增加与产后4周内子宫尺寸略大但显著相关。产后6至8周子宫恢复到非妊娠时的大小。子宫复旧与婴儿出生体重或母乳喂养无关。
