Values of PRWR <0,18 and EASWR <0,15 in 63 % of cases corresponded to an unsatisfactory result on the Rintala scale and was accompanied by fecal incontinence. A good function of anal function was observed in 58 % of patients with PRWR >0,18 and EAsWr >0,15.anorectal malformationsMRTRintala scalemanometryаноректальные пороки развитиямагнитно-резонансная томографияшкала Rintalaманометрия[Аверин В.И., Ионов А.Л., Караваева С.А. и др.
