The study was conducted to evaluate the efficiency of Doppler ultrasonography for diagnosis of uterine torsion in does. Ten does suffering from uterine torsion were examined clinically and using Doppler ultrasonography at the time of presentation and one hour after correction of torsion and subsequent foetal extraction. Pulsatility index (PI) and resistive index (RI) in the arteries ipsilateral and contralateral to the side of uterine torsion were recorded. Mean pulsatility and resistive indices of left and right middle uterine arteries of ten does at the initiation of kidding was measured and their average was taken as control. The PI and RI as highest in ipsilateral uterine artery of torsion affected does than contralateral and normal kidding does; the value was lowest in normal does. The difference in PI and RI were highly significant (p<0.01) between ipsilateral and contralateral uterine arteries of affected does as well as with uterine arteries of normal does. After foetal delivery no significant difference (p>0.05) existed in these values.
