| Abstract: | 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%. |
