Urinary tract infection（UTI） is clinically common and can develop in both men and women

young and old.The incidence is the highest among women.Repeate episodes of urinary tract infections are called recurrent UTI（RUTI）

may occur due to poor hygiene habits

immune abnormalities

and the presence of structural abnormalities of the urinary tract.RUTI is a risk factor for pyelonephritis

which causes the formation of renal scarring

leading to impaired renal function and progression to chronic renal failure.RUTI in infants and children can lead to impaired renal development and scar formation

resulting in permanent renal parenchymal damage with far more severe consequences than in adults.The purpose of this article is to find the susceptibility factors and etiology for the occurrence of RUTI

to explore intervention strategies for RUTI

and to evaluate some strategies in order to provide a reference for clinically relevant treatment.
