[The effect of chronic kidney disease on the course and outcome of pregnancy].

In order to estimate the effect of renal disease on the pregnancy, and the effect of pregnancy on the natural course of renal disease, the course and outcome of the 37 pregnancies was analyzed in gravidas with chronic renal disease. The women were cared for between 1978 and 1990 at the Department of Obstetrics, School of Medicine University of Zagreb. Analysis of the results in this article is retrospective. Thirty-six pregnancies finished by vaginal or cesarean delivery or by abortion, while one pregnancy was ectopic and ended by laparotomy during the 20th week. There were 31 live births from 36 fetuses (86.1%), 5 stillbirths (13.19%), of which 2 pregnancies ended in fetal death (abortion). In addition, there were 6 instances of neonatal death (8.3%). Twenty-five percent of pregnancies finished before 37 weeks of gestation. In 6 of 34 (17.6%) deliveries amniotic fluid was meconium stained, and 5 of 31 (16.1%) infants were born hypoxic. There were 29 percent of growth retarded liveborn fetuses. Perinatal mortality was 167/1000. Renal insufficiency was noted in 12 of 37 (32.4%) pregnancies, 54% of pregnant women had hypertension, 8.1% hyperkalemia, 78.4% were anemic, 27% had significant bacteriuria and 21.6% overt pyelonephritis. There was one case of acute deterioration in renal function that required hemodialysis, and one case of preeclampsia. Renal insufficiency or hypertension reduce drastically the chances for a successful outcome of pregnancy in gravidas with kidney disorders. However renal insufficiency in the presence of hypertension, carries even poorer prognosis, with perinatal mortality of 428/1000.
