Comparison between male and female rabbit renal arteries by Doppler ultrasonography

Doppler ultrasonography is important in diagnosis of renal diseases by demonstrating vascular anatomy and hemodynamics. Decreased renal blood flow may be the first sign of dysfunction and can be evaluated by doppler ultrasound. The purpose of this study was to obtain the normal images of color doppler and estimation of blood flow velocity parameters of renal arteries and abdominal aorta in adult healthy، New Zealand white rabbits. Therefore، 20 healthy rabbits (10 male and 10 female) with a mean age of 15 months (12 to 21 months) and a mean weight of 1. 7 kg (1. 4 to 2. 6 kg) were selected. In this study، indices of abdominal aorta and renal arteries including PSV، EDV، RI، PI، MV، VF and pulsed Doppler spectral were compared between the sexes. Mean PSV and EDV of abdominal aorta in male and female rabbits were 68. 95 and 76. 19cm/sec respectively. Mean PSV and EDV of renal artery in males and females were 42. 12 and 30. 95cm/sec respectively. Numerical values obtained for the PSV، MV and VF of the abdominal aorta and EDV and VF renal arteries between males and females were different (P<0. 05). The results obtained in this study can be used as indicators of natural indices in diagnosis of associated diseases in New Zealand white rabbits.
