The relationship between reactive thrombocytosis and the level of
urinary tract infections was studied in 48 children. Platelets were
counted before, during and after treatment. Reactive thrombocytosis was
noticed in 74% of children with upper and in 14% with lower urinary
tract infections. A significant rise in the platelet count presented in
another five children (15%) with upper urinary tract infections.
Conclusion: Reactive thrombocytosis was found almost exclusively in the
renal parenchymal infections, usually during the recovery phase
