COMPARISON OF FETAL RENAL ARTERY DOPPLER IN PATEINTS WITH OR WITHOUT OLIGOHYDRAMNIOS IN 3rd TRIMESTER

Abstract

Background: When the amniotic fluid index (AFI) is less than 5 cm or the single deepest pocket is less than 2 cm, the medical condition known as oligohydramnios occurs. At any stage of pregnancy, 3–4% of expecting women have low amniotic fluid. About 1% to 5% of pregnancies result in oligohydramnios. According to prospective research at the University of Texas South-Western Medical Center, 2.3% of people have oligohydramnios. In the United States, 953 women in the third trimester over a 12-month period showed similar outcomes. Summertime saw a higher rating of oligohydramnios than the rest of the year. Objectives: To compare the fetal renal artery Doppler in patients with or without oligohydramnios in third trimester. Methodology: This is a case control study. This study includes the women in third trimester of pregnancy with oligohydramnios or normal liquor level and excludes the pregnant women with known maternal or fetal anomaly. Every expectant mother undergoing obstetrical US in the third trimester using a Toshiba Aplio Mx with a curvilinear transducer operating at 7–15 MHz, this study was done at Meer Khan children and family hospital, Lahore. Results: Display the several parameters (PSV, EDV, RI, and PI) measured in the right fetal artery and classified as either normal or abnormal. Right fetal renal PSV, ED, RI, and PI were observed to differ significantly between the normal and oligo groups. PSV and PI did not differ significantly, however EDV (p=0.017) and RI (p<0.001) did. Significant differences between normal and oligo were observed in left fetal renal PSV, ED, RI, and PI. EDV, RI, and PI do not significantly differ between the groups. PSV showed a significant difference across groups (p=0.015). Conclusion: Our study concluded that the RI of right renal artery and PI and PSV of left renal artery are elevated in oligohydramnios
