Problems Associated with Pregnancy in Renal Allograft Recipients

Abstract

Of 18 pregnancies in 11 renal transplant recipients, three were terminated and in the remaining 15 (in 8 women) there were 10 live births (including one set of twins), five intrauterine deaths, and one spontaneous abortion. Graft function deteriorated in six women, from obstruction of the transplanted ureter in two, recurrent glomerulonephritis in two, rejection in one, and pelvi-ureteric junction obstruction in one. Hypertension worsened or developed in all but one of the pregnancies and proteinuria appeared in eight. Of the 10 live births only one reached 38 weeks gestation (mean 35 weeks) and four neonates were small for gestational age. One infant died early from intraventricular hemorrhage and hyaline membrane disease, one fetus had hydrocephalus, and the others were normal. Factors associated with a poor fetal outcome were deterioration in graft function during pregnancy, pre-existing hypertension, or the development of hypertension before the third trimester
