Pre-eclampsia is an hypertensive disorder appearing during pregnancy, inducing serious maternal, fetal and neonatal mortality and morbidity. Podocyn could be identified in the urine, before proteinuria, a key element in the diagnostic of pre-eclampsia. Preventive treatment using aspirin could be administrated in early pregnancy. We hypothesized that podocyturia could be an early indicator of preeclampsia. This is a prospective, non-interventional, monocentric study.
