Severe oligohydramnios and renal dysplasia were detected in one of diamniotic, monochorionic twins at 19 weeks' gestation. At birth (37 weeks), the affected twin had only minimal extrarenal Potter's features and mild pulmonary hypoplasia, despite severe renal dysplasia due to posterior urethral valves. The effects of virtual absence of amniotic fluid during the latter half of gestation from bilateral renal dysplasia were ameliorated by the presence of a normal co-twin and its normal amniotic fluid levels, even though the affected twin did not share the same amniotic fluid.
在孕19周时，双羊膜囊单绒毛膜双胎中的一个被检测出严重羊水过少和肾发育不良。出生时（37周），尽管因后尿道瓣膜导致严重肾发育不良，但受影响的双胎仅有轻微的肾外波特氏面容特征和轻度肺发育不全。由于双侧肾发育不良，妊娠后半期几乎没有羊水，然而正常的双胎及其正常的羊水水平缓解了这种影响，即便受影响的双胎并不共享同一羊水。
