What this trial studies

This observational study aims to validate a classifier based on fetal urine peptidome analysis to predict post-natal renal function in fetuses diagnosed with Posterior Urethral Valves. It involves collecting fetal urine, post-natal urine, post-natal serum, and possibly amniotic fluid to explore potential biomarkers. The analysis will be conducted at the Institute of Metabolic and Cardiovascular Diseases in Toulouse or through fee-for-service suppliers. The goal is to improve the stratification of affected fetuses for better clinical outcomes.

Who should consider this trial

Good fit: Ideal candidates include male singleton fetuses diagnosed with megabladder and urinary tract anomalies confirmed by ultrasound.

Not a fit: Patients who do not have urinary tract anomalies or those who refuse to participate in the study may not benefit.

Why it matters

Potential benefit: If successful, this study could lead to improved predictions of renal function in newborns, allowing for better management and treatment strategies.

How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, indicating a novel exploration in this area.
