In twelve twin pregnancies with normal amniotic fluid volume, the urine output of each twin was lower than in fetuses from singleton pregnancies, and the combined urine output of both twins was between the 50th and 95th centile for singletons. In three twin pregnancies at 21-24 weeks of gestation with acute polyhydramnios, presumed to be due to the twin-twin transfusion syndrome, the urine output of the smaller fetus was zero and that of the larger was above the 95th centile for normal singleton pregnancies. These three pregnancies were managed by repeated amniocenteses and rapid drainage of large volumes of amniotic fluid. With advancing gestation, there was a tendency for normalization of urine output in the twins.
在12例羊水体积正常的双胎妊娠中，每个胎儿的尿量均低于单胎妊娠胎儿，且两个胎儿的尿量总和处于单胎妊娠胎儿的第50至95百分位之间。在3例妊娠21 - 24周、伴有急性羊水过多的双胎妊娠中，推测是由于双胎输血综合征所致，较小胎儿的尿量为零，而较大胎儿的尿量高于正常单胎妊娠的第95百分位。这3例妊娠通过反复羊膜腔穿刺和大量羊水快速引流进行处理。随着孕周增加，双胎的尿量有趋于正常的倾向。
