[Acute obstructive renal insufficiency and pregnancy. Apropos of a case]

Acute renal failure caused by obstruction by the gravid uterus is a rare complication of pregnancy. We report a case of obstructive acute renal failure in a patient at 28 weeks of gestation. Serum creatinine was 65 mg/l. Ultrasound examination showed a solitary right kidney. The course was marked by premature delivery. Renal function spontaneously returned to normal. This case suggests that acute obstructive uropathy should be considered to be a physiological phenomenon, especially on the right side.
