Oligohydramnios-polyhydramnios sequence in twin pregnancies may be managed by aggressive amniocentesis and is described in nine consecutive cases. In four of the nine pregnancies both twins survived, one pair died in the neonatal period, and the other four pairs all suffered intrauterine death. The median number of amnioreductions performed was five (range 2-7). In this series the reaccumulation of urine in the bladder of the 'stuck twin' was a predictive prognostic marker of survival in both twins, with a sensitivity and specificity of 100%.
双胎妊娠中的羊水过少-羊水过多序列征可通过积极的羊膜腔穿刺术进行处理，本文描述了连续9例该病症。9例妊娠中，有4例的两个胎儿均存活，1例在新生儿期死亡，另外4例均发生宫内死亡。羊膜腔穿刺减压的中位次数为5次（范围为2-7次）。在本系列病例中，“黏附胎儿”膀胱内尿液的再次积聚是两个胎儿均存活的预测性预后标志物，其敏感性和特异性均为100%。
