ACUTE MATERNAL OBSTRUCTIVE RENAL-FAILURE IN A TWIN GESTATION DESPITE NORMAL PHYSIOLOGICAL PREGNANCY-INDUCED URINARY-TRACT DILATION

Obstructive renal failure due to an overdistended uterus is a very rar e complication of pregnancy. Most previously reported cases have invol ved twin gestations, the majority occurring in the presence of polyhyd ramnios. We describe a patient with a twin gestation who developed acu te obstructive renal failure despite only very mild physiological preg nancy-induced dilation of the urinary collecting system in the absence of polyhydramnios. This case suggests that acute obstructive uropathy should be considered as a rare cause of acute renal failure even in c ases with seemingly normal pregnancy-induced physiological urinary tra ct dilation.
