Pregnancy in patients with previous successful renal transplantation

Objective: To evaluate the risk factors affecting pregnancy, perinatal outcomes, and short-term graft condition in women who underwent renal transplantation. Method: Between May 1998 and January 2005, the histories of 20 pregnancies in 17 renal transplant recipients were reviewed retrospectively at the Ministry of Health Aegean Obstetrics and Gynecology Teaching Hospital. Result: There were significant associations between high serum creatinine level (> 1.5 mg/dL) prior to pregnancy and preterm delivery (P = 0.04), and between short interval between transplantation and pregnancy (< 2 years) and increased rate of cesarean sections (P=0.04). There were no significant changes in serum creatinine levels during pregnancy in these women, and there were no acute rejection and graft loss during pregnancy or in the 6 months following delivery. Conclusion: These findings suggest that, although pregnancy does not adversely affect short-term renal allograft function, the rates of obstetric and perinatal complications are increased. Risk factors present before conception are a short interval between renal transplantation and pregnancy and poor renal function. (c) 2005 International Federation of Gynecology and Obstetrics.
