  • 10% of individuals have urinary tract malformations, although many are asymptomatic
  • 15% of congenital urogenital anomalies are secondary to an underlying chromosomal disorder
  • In children, 20% of chronic renal failure is due to renal dysplasia or hypoplasia
  • In adults, 10% of chronic renal failure is due to adult polycystic kidney disease
  • Mass ultrasound screening detects congenital renal and urinary tract anomalies in 1% but not recommended since most would ultimately be detected via symptoms; most commonly vesicoureteral reflux, ureteropelvic junction obstruction, ectopic kidney, renal dysplasia (Pediatr Nephrol 2012;27:949)
