Pregnancy after renal transplantation: a retrospective study at the military hospital of Tunis from 1992 to 2011

Abstract

IntroductionOur study objective was to analyze the optimum conditions for pregnancy in kidney transplanted women. For that, we conducted a retrospective study was from 1992 to April 2011 about 17 pregnancies in 12 kidney transplanted patients followed in the Department of Obstetrics and Gynecology and Organ Transplant Unit of the Military Hospital of Tunis.MethodsWe studied nephrological parameters and obstetric pathologies encountered during pregnancy and the potential impact of pregnancy on graft. Our main outcome measures were: time between renal transplantation and conception, birth of a living child, renal graft defect.ResultsThe mean age at the time of renal transplantation was 30.11 years. The average age at the time of conception is 34.23 years. The average time between renal transplantation and the occurrence of pregnancy was 46.94 months. More than 40% of pregnancies were not planned. Of the 17 pregnancies, 12 have advanced beyond the first trimester with 91.6% resulting in the birth of a living child. Toxemia was found in 60% of cases, low birth weight in 50%, preterm in 30% and intrauterine growth retardation in 20% of cases. Cesarean section was indicated in all cases. Graft survival was 90% with a mean of 6 years after delivery.ConclusionPregnancy in kidney transplanted patients is a high-risk pregnancy, but pregnancy does not appear to affect graft function through certain conditions.
