Renal Failure of the Surviving Fetus After Intrauterine Death of the Co-Twin

Abstract

Twin pregnancies are considered at a higher risk for fetal mortality than singleton pregnancies. The antenatal death of one of the twins is associated with an increasing rate of cerebral impairment and lesions in other organs in the surviving fetus, especially if the pregnancy is monochorionic. We describe a case of isolate renal failure becoming evident gradually after birth in a surviving twin after the antenatal death of the co-twin. Considering the deleterious effects of vascular disruption in a surviving twin, our findings suggest careful investigation of renal function, even if no intrauterine signs of diminished renal function were previously detected.
