Background
The aim of this study was to describe the pattern of urinary tract infection (UTI) and bladder function in women who had experienced recurrent UTI in childhood, with and without consequent renal damage, and followed for three to four decades.
Methods
A population-based cohort of women who had been followed from the first UTI in childhood and previously studied at a median age of 27 years was studied at a median age of 41 years. Renal damage was evaluated by 99mTc-dimercaptosuccinic acid scan. Clinical data were collected on the pattern of recurrent UTIs and bladder function.
Results
A total of 86 women were investigated, of whom 58 had suffered renal damage and 28 were without. Febrile UTI in adulthood had occurred in 22 patients, once in 15 women and twice or more in seven women. There was a change in the infection pattern over time, evident already in childhood, that was characterized by a decrease in UTI frequency and a shift from febrile to non-febrile infections. A significant association was found between renal damage and febrile UTI (p = 0.046), and between abnormal bladder function and recurrent non-febrile UTI (p = 0.002). There was no relationship between persisting vesicoureteral reflux (VUR) and proneness to either symptomatic UTI (p = 0.99) or febrile UTI in adulthood (p = 0.14).
Conclusions
Among this study cohort there was a continuously decreasing rate of febrile UTI in adulthood. Persisting VUR was not related to UTI in adulthood. Abnormal bladder function was related to non-febrile UTI but not to febrile UTI.
