Uterine growth in twin pregnancy by measurement of total intrauterine volume.

Total intrauterine volume (TIUV) was determined serially in 27 twin pregnancies from which a nomogram was constructed. At the beginning of the second trimester, TIUV was similar to that in singleton pregnancy; by the 18th week it had become twice as large, and remained so until late in pregnancy. Labor was preceded more frequently by a slowing than by an acceleration of uterine growth.
