Abstract
We report on a patient with an eight-year history on maintenance hemodialysis treatment without residual renal function in whom pregnancy was successfully managed through to the 29th week. During this time, under carefully modified dialysis treatment, the nephrologic course, as well as materno-fetal flow relationships were unremarkable. Fetal development was appropriate for gestational age. However, pregnancy was complicated by polyhydramnios, which necessitated i.v. tocolysis. In the 28 + 6th week of gestation, cesarean section was performed because of an antibiotic-resistant fever of unclear origin which ceased within two days of delivery. Although the postnatal course of the adequately developed baby was complicated by the respiratory distress syndrome, normal development continued. We emphasize that the intensive interdisciplinary cooperation of nephrologists and obstetricians is imperative for the successful management of pregnancy under these conditions. In these pregnancies, the main fetal problems consist of premature labor because of polyhydramnios, preterm delivery, intrauterine growth retardation and stillbirth. The mother is threatened by the development of superimposed pre-eclampsia, left ventricular failure because of volume overload and progressive anemia. In order to maintain a well-balanced homeostasis, intensification of dialysis therapy by an increase in frequency and duration is the most important therapeutic approach. Accurate fetal monitoring including frequent examination of the feto-maternal circulation by Doppler sonography as well as attentive surveillance of the mother is required to recognize the above mentioned complications.
