Pregnancy outcome in renal transplant recipients

Abstract

Objective: To correlate pregnancy outcome with complications in pregnancy and transplantation-to-pregnancy interval in renal transplant recipients in Croatia. Method: Data on 23 pregnancies after prepregnancy stabilization of blood pressure and normalization of graft function were retrospectively analyzed. Result: The mean interval between transplantation and conception was 3.1 years. Primary renal disease was chronic glomerulonephritis in 7, chronic pyelonephritis in 7 and agenesis of right kidney and stenosis of left renal artery in 1 patient. There were 10 term and 5 preterm deliveries, 6 induced and 2 spontaneous abortions. The mean gestational age was 38.1 weeks and the mean newborn birthweight was 3015 g. The prematurity rate was 21.7%. Patients with arterial hypertension in pregnancy, elevated serum creatinine level and bacteriuria, as well as those with conception occurring less than 2 years after transplantation, had a higher rate of therapeutic and spontaneous abortions, preterm deliveries and low birth weight infants. Conclusion: The interval between transplantation and conception, as well as allograft function during pregnancy, seem to be of great importance for successful obstetric outcome in renal transplant patients.
