Abdominal pain is a common problem of patients of all ages. In childhood a sudden abdominal pain usually requires admission to the hospital to rule out a health threatening condition.
The most common causes of abdominal pain in childhood are acute gastrointestinal infections (for example viral gastroenteritis), functional dyspepsia, appendicopathy, less frequently biliary or renal colic, and acute pyelonephritis. Congenital anomalies of the urinary tract may be another, rather rare cause of pain, however it may not manifest for long asymptomatic period.
