In view of age, the pyeolonephritis is more common among children aged 0-3 and also more common in girls (64%) then in boys (36%). The secondary pyelonephritis due to kidney abnormalities (62.5%), vesicoureteral reflux (7.5%) and kidney stone (5%) is common findings among children. 

Conclusions:

1. The most common type of microorganisms as a cause of pyelonephritis is E.Coli (41.17%0.
2. High prevalence of this pathologic condition was observed in children age between 0-3 years, and most of them were girls (64%).
3. There is high prevalence of secondary pyelonephriris among our children and it is caused by congenital defects (62.5%), vesicoureteral reflux (7.5%), and kidney stones (5%).
