This was prospective study carried out in -Khartoum state –Sudan, Khartoum Bahri Teaching hospital in the period from august 2016 to December 2018. The main aim of the study was to assess umbilical arteries and outcome in 33-46 weeks GA using Doppler ultrasound. The study was done in 197 pregnant women with normal singleton pregnancy with mean age 28 years, with gestational age by Last Menstrual period (GA LMP) 33-46 weeks, classified into three group (Group one in GA ranged 33-38 weeks 6 days, Group two in age group 39 weeks -40 weeks (term) and Group three 40 weeks 1day to 46 weeks GA LMP (post-term) , no maternal medical condition that may affect pregnancy outcome such as diabetic and hypertension. The data was collected by data collection sheet designed especially for this study and including all variables; then analyzed by statistical package for social sciences (SPSS). The study found that most of them were nulliparous 78.8%. Significant difference in Doppler indices of UA were noted in these three group of gestational age (p < 0.05) except for PSV and EDV which had no significant difference in these three group of GA ( p>0.05), the study found that there was weak significant negative correlation between UA PI,RI ,S\D ratio and GA LMP (p <0.05),the study clarified that as GA increased Doppler indices of UA decreased RI, PI, S\D ratio. There is significant relation between GA and adverse outcome as prevalence of oligohydramnios, macrosomia and cesarean section c\s increased in post-term pregnancy (p<0.01). The study confirmed that no significant differences in all these Doppler indices in patients post term with adverse versus post term with normal outcome.
