Trends and risk factors of extended-spectrum beta-lactamase urinary tract infection in Chinese children: a nomogram is built and urologist should act in time

BACKGROUND: To investigate the etiological characteristics and risk factors of extended-spectrum beta-lactamase (ESBL) urinary tract infection (UTI) and construct a corresponding nomogram to predict the probability of ESBL(+) UTI. METHODS: We retrospectively reviewed the records among patients experiencing UTI events in Chongqing Medical University Affiliated Children’s Hospital from 1994 and 2019. RESULTS: A total of 854 patients with UTI were evaluated and ESBL-producing bacteria increased significantly. Significant potential risk factors of ESBL-UTI were congenital urological abnormalities, vesicoureteral reflux, neurologic disorder, age
