Doppler ultrasound versus testicular scanning in the evaluation of the acute scrotum.

A comparative prospective study of the Doppler ultrasonogram, the testicular scan and the surgical findings in patients with an acute scrotum is presented. The testicular scan was found to be the most reliable diagnostic method since it correlated with the surgical findings in 100 per cent of the cases. The Doppler ultrasonogram proved to be useful since it gave a positive correlation in 79 per cent of the cases studied.
