Background
Uterine and Umbilical artery Doppler ultrasound is a safe and an important tool in assessing
fetal well-being thus predicting normal and abnormal indices during pregnancy.
Objectives
To evaluate the uterine and umbilical artery Resistive and pulsatility indices in healthy
singleton Kenyan women and determine the local reference ranges. .
Methodology
This was a prospective longitudinal study that included 202 singleton pregnant mothers done
at Kenyatta National Hospital Radiology department and Antenatal Clinic. Using Bmode,colour and pulsed Doppler ultrasound the RI and PI for both uterine and umbilical
arteries were obtained during the second trimester (21-25 weeks) after which the patients in the
study who did not develop any of the exclusion criteria were scanned again in the third
trimester(31-35 weeks). All scans were done independently by the Principal investigator and
certified by a qualified radiologist at each visit. Data collection forms were used to record the
mentioned parameters at every ultrasound session and Independent Student’s T-test done on
the mean RI and PI values using SPSS( Version 21).A comparison was made to other similar
studies worldwide
Results
The mean of the normal uterine and umbilical artery values were similar to most published
reference values from other parts of the world. No correlation between these indices and
maternal parameters were found in this study.
Conclusion
Uterine and umbilical artery Doppler indices among normal singleton Kenyan women are
similar to those of the developed world, therefore using reference values from those studies
may be used in our environment. Future research with a more extensive longitudinal study and
shorter scan intervals may be required to provide data covering all GAs and to validate the
preliminary findings from this report.
