Abstract: Anorectal malformation (ARM) accounts for the first place of digestive tract malformations in children, with the incidence of 1/5 000-1/1 500 in newborns.ARM is typically manifested as anal stenosis or anal atresia with or without fistulas and persistent cloaca.Genitourinary malformation is the most common malformation associated with ARM, with the incidence ranging 26%-55%.There were 35%-50% of ARM children develop spinal cord peripheral abnormalities or neurogenic lower urinary tract dysfunction, which usually causes voiding dysfunction associated with ARM.Urodynamic study is the best method to analyze the changes of lower urinary tract function, which can provide an objective classification for bladder and urethral function and guide the formulation of precision treatment plan and therapeutic efficacy during the follow-up period.This study aims to review the cause of voiding dysfunction asso-ciated with ARM and its urodynamic changes.
