Herthelius M, et al. - In the present study, the researchers sought to establish long-term outcome in an unselected group of children with antenatally detected urinary tract dilatation (UTD). For this analysis, 71 out of 103 children born in 2003–2005 and diagnosed with antenatal UTD agreed to engage in a 12–15-year follow-up including blood and urine samples, a kidney ultrasound exam, and kidney scintigraphy. The authors conclude that the outcome is excellent in children with postnatal APD ≤ 7 mm, without calyceal dilatation, normal bladder, ureters, and kidney parenchyma. In these patients, there is no need for long-term follow-up.
