P93Comparison of renal artery blood flow velocity waveform and renal volume in normal and growth‐retarded fetuses

Résumé fourni par la source

Objective The purposes of this study are to evaluate renal artery blood flow velocity waveform and renal volume in growth‐retarded fetuses compared with normal fetuses. Method Doppler flow velocity waveform of renal artery and renal volume measured by three‐dimensional ultrasonography were obtained in 78 normal fetuses at gestational age from 25 to 39 weeks and 18 cases of IUGR fetuses weighted below the tenth percentile at birth. Results; Fetal renal artery pulsatility index (PI) decreased throughout the gestational period (r = 0.703, p 0.0001). In growth‐retarded fetuses, although all of them had abnormal Doppler velocity waveform of middle cerebral artery, renal pi was not increased significantly. Fetal renal volume increased throughout the gestational period (r = 0.834, p 0.0001). and in growth‐retarded fetuses, renal volume of all was below the fifth percentile of normal fetuses. Conclusion Fetal renal volume measured by three‐dimensional ultrasonography may be the helpful parameter in the evaluation of growth‐retarded fetus.
