Posterior urethral valves: are neonatal imaging findings predictive of renal function during early childhood?

Background: Obstructive renal dysplasia as observed on US is associated with posterior urethral valves and is regarded as predicting poor renal functional outcome.

Objective: To investigate whether any characteristic of urinary tract imaging at birth is predictive of renal function in children with prenatally diagnosed posterior urethral valves.

Materials And Methods: We reviewed clinical data including renal function (at birth and up to 3 years of age) and clinical outcome (urinary infection, dialysis, renal transplantation).

Fetal liver iron overload: the role of MR imaging.

Objective: To assess the potential role of MR imaging in the diagnosis of fetal liver iron overload.

Methods: We reviewed seven cases of abnormal liver signal in fetuses referred to MR imaging in a context of suspected congenital infection (n = 2), digestive tract anomalies (n = 3) and hydrops fetalis (n = 2). The average GA of the fetuses was 31 weeks.
