排尿障礙治療中心 版權所有 Recurrent UTI in Children In neonates UTI occurs more commonly in boys (2.7%) than girls (0.7%) In children >1 y/o UTI is 9 times more frequent in girls than boys In asymptomatic children reflux is 1% Reflux is diagnosed in 50% of infants 4 years

排尿障礙治療中心 版權所有 Evaluation of UTI in Children All children regardless of sex and age be examined by ultrasound and VCUG after first UTI Radionuclide cystograpgy is more sensitive to detect VUR in younger child Renal scarring can be detected by ultrasound, IVP, DMSA scintigraphy

排尿障礙治療中心 版權所有 Recurrent UTI or VUR In girls with UTI, 40-60% have symptoms of urgency, frequency, squatting behaviour, and diurnal incontinence. In most girls with VUR, infrequent voids with large volume In boys, frequent small voids in more children with VUR (36%) than healthy boys (15%)

排尿障礙治療中心 版權所有 Vesicoureteral Reflux Primary – A short submucosal tunnel Secondary – Increased bladder pressure due to neuropathic bladder, anatomical abnormality, outlet obstruction At birth the majority of VUR is seen in boys, by age 1 the incidence of VUR is greater in girls Many girls have secondary VUR because of voiding dysfunction
