[Urinary tract infection in childhood--an overview. 2. Therapy]

The prevention of pyelonephritic scarring is the main aim of the treatment of urinary tract infections (UTI) in children. Therefore, an early diagnosis and an immediate and effective antibiotic therapy of acute pyelonephritis is necessary, especially in the first years of life. Furthermore, recurrences of UTI should be prevented in children at high risk of developing renal scarring (vesicoureteric reflux, obstruction of the urinary tract, injured kidneys, bladder dysfunction). In the present paper recommendations are given for antibiotic therapy of acute UTI, antibacterial prophylaxis of reinfections and treatment of bladder dysfunctions.
