Abstract:
Vesicoureteral reflux (VUR) is a common condition in children. It may cause and maintain urinary tract infections, eventually leading to progressive renal damage and end-stage renal disease. Ideally, VUR should be detected and treated before renal scarring occurs. Although fetal hydronephrosis on antenatal ultrasound may be the first indicator, the role of further diagnostic investigations in these newborns is still controversial. Because VUR is an inherited condition, offspring of women with a family history of VUR and urinary tract infection should be screened closely for early detection of VUR. Once diagnosed, however, the optimal management of VUR (i.e. medical or surgical treatment) remains controversial. Evidence-based treatment recommendations, like the American Urological Association guidelines, may aid physicians in their therapeutic decision making, but cannot replace personal experience or surgical skill.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
