Pre-eclampsia is an hypertensive disorder appearing during pregnancy, inducing serious maternal, fetal and neonatal mortality and morbidity. Twenty four hours proteinuria is a key element to define pre-eclampsia severity but is delaying the result by 24 hours and constraining for the patient. A simple and rapid indicator for severe preeclampsia would help clinicians to make appropriate decision in patient management. We hypothesized that urinary podocyturia is correlated to preeclampsia severity. This is a prospective, non-interventional, monocentric study.
