Proteomic Analysis of Amniotic Fluid to Predict Postnatal Renal Function in Fetuses With Renal and Urinary Tract Malformations

This intervention consists of analyzing the amniotic fluid proteome using capillary electrophoresis coupled with mass spectrometry (CE-MS). The goal is to evaluate a predefined 98-peptide signature that predicts postnatal kidney function in fetuses with bilateral congenital anomalies of the kidney and urinary tract. Unlike standard prenatal assessments based on ultrasound and fetal biochemistry, this method provides a molecular-based prognostic tool to improve decision-making regarding pregnancy management and neonatal care
