| Sumario: | Background: Pregnancies in women with end stage renal failure are uncommon. However, correction of anemia and improvement in dialysis techniques increases the rate of successful pregnancies. Aim: To describe a 16 years’ experience treating pregnant women on hemodialysis and to analyze maternal-fetal outcomes. Materials and Methods: Observational study of a dialysis center historical cohort in a university hospital, between 2001 and 2016. Results: Thirteen pregnancies were found in 11 women aged 23 to 32 years, 77% on dialysis prior to pregnancy. Residual diuresis was 1,300 [625-1,575] mL in 24 hrs. The baseline hemoglobin was 9.0 [7.6-9.9] g/dL and 92% of patients did not use contraception. The pre-dialysis blood urea nitrogen was 34 [29-36] mg /dL. An ultrasound to confirm pregnancy was done in all. At 23 [14-25] weeks of pregnancy, dialysis hours were increased, reaching 24 [19.5-24.0] hours per week. The most common complications were severe arterial hypertension (54%), severe anemia (46%), polyhydramnios (31%) and severe intrauterine growth retardation (IUGR) (23%). The median time of pregnancy at delivery was 34 [29-34] weeks. Neonatal median hospitalization length was 4 [4-32] days, with 18% of neonatal deaths. Conclusions: Pregnancies in dialysis are no longer exceptional. Despite better maternal and fetal outcomes, morbidity and mortality remains higher than in the normal population, which makes multidisciplinary management essential. |
