From 1958 to 1987, 81 cases of pregnancy-related acute renal failure (PR-ARF) were observed (9% of the total number of acute renal failure [ARF] needing dialysis).

Neither disseminated intravascular coagulation (DIC), microangiopathic hemolytic anemia nor prostacyclin imbalance were significantly related to the severity of renal damage.

Abstract
From 1958 to 1987, 81 cases of pregnancy-related acute renal failure (PR-ARF) were observed (9% of the total number of acute renal failure [ARF] needing dialysis). In the three successive ten-year periods (1958-67, 1968-77, 1978-87) the incidence of PR-ARF fell from 43% to 2.8% with respect to the total number of ARF, and from 1/3,000 to 1/15,000 with respect to the total number of pregnancies. Maternal mortality was high (32%), with 5 cases of death in the last ten years. Irreversible renal damage was recorded in 11.6% of PR-ARF, and, in particular, in 26.3% of cases in preeclampsia-eclampsia (PE-E). Worse maternal and renal prognosis occurred in PE-E complicated by abruptio placentae. Neither disseminated intravascular coagulation (DIC), microangiopathic hemolytic anemia nor prostacyclin imbalance were significantly related to the severity of renal damage. Heparin therapy did not modify DIC evolution and renal outcome and was aggravated by severe hemorrhagic complications. In conclusion, PR-ARF has become a rare, but still critical occurrence, and the most effective measures would be a program of careful prevention.
