ABSTRACT

Objective:

The aim of our study was to determine the role and the importance of fetal renal artery doppler ultrasonography in high-risk pregnants.

Study Design:

Over 28 weeks' gestation 60 high-risk and 35 normal (control group) pregnants were in our study group.The high-risk group included; Preeclampsia (19),surmaturation (18), preterm(7),multiple pregnancıes(6), Diabetes mellitus (4),premature rupture ofmembrane (4) andfetal anomaly (2).Pulsatility index (P/) measured by usingfetal renal artery doppler ultrasonography. Pregnants whom evaluations with doppler was not normal, were observed by USG (ultrasonography) once and NST (nonstress test) twice ina week.The both groups were compared by delivery type, birth weight, neonatal death and arnnion fluid volume.The statistical ana/ysis was by X2, P<0,05 considered significant.

Results:

In both groups the fetal renalartery pulsatility index decreased (P<0.05) at the Iate time of pregnancy. In high-risk pregnancy group wıth non-reactive NST. renalartery main Pl was 3.92, with reactive NSTmain Pl wasfound 1,62.(P<0,05).ln control group, Pl was 1,88 with reactive NST and 2,42 with non reactive NST. The ratio of cesarean seetion in control group was %37.2, in high-risk group was % 51,6 .. The ratio of neonatal death in high -risk group was %16,7 (10!60), in control group %2,8 (1135).The main birth weight was in order 2653,3 and 3292,8 gr. lt was found out that, the prognose in high-risk pregnants is worser than the control group.

Conclusion:

Our data suggests that,fetal renal artery doppler u/trasonography is more available than NST, USG, CST especially in early gestationes for prenatal observations. It' s not just for rutin monıtoring, It' s combine d w ith the other technics for monitoring the high-risk pregnancies.
