Summary: The investigators propose a standardized prenatal management, based on the scientific evidence published in the literature, to manage prenatally fetuses with lower urinary tract obstruction (LUTO). The present study is a prospective registry that will evaluate and validate this standardized prenatal management for LUTO.
Summary: We hypothesize that overnight catheter drainage (OCD) of the urinary bladder might improve bladder dynamics and subsequently lead to improvement or resolution of hydronephrosis (HN) and renal function in boys who underwent PUV ablation. Patients who have persistent HN and bladder dysfunction at least one year after PUV ablation will be randomly allocated into two groups: the first group (control g...
Summary: Validate the use of fetal urine peptidome-analysis and explore amniotic fluid markers for the stratification of fetuses with Posterior Urethral Valve for post-natal renal function.
