Goal: Determining the place of Uricemia associated with other biochemical makers in the prediction of fetal-maternal complications during preeclampsia. Material and method: This is a prospective, cross-sectional study of 75 pre-eclamptic women in three maternities in Kinshasa, Democratic Republic of Congo, during the January to December 2013. The values of the following biochemical markers: uricemia, proteinuria and creatinemia were correlated with maternal and fetal prognosis. Results: This study showed that hyper uricemia associated with massive proteinuria and a high creatinine level correlated with an unfavorable pregnancy outcome and the occurrence of major materno-fetal complications such as eclampsia (X-squared = 24.3598, ddl = 2, p-value = 0.000005) and low birth weight (p = 0.001, R2 = 0.08). Conclusion: In view of these results, it appears necessary to ensure these biochemical markers systematically in the monitoring of pre-eclampsia.
