Testicular torsion: management with ultrasonic Doppler flow detector.

The use of the ultrasonic Doppler flow detector in the management of acute testicular torsion is described. The Doppler can be used to diagnose torsion accurately and also to monitor manual detorsion. In this series detorsion was a reliable procedure which avoided emergency exploration in 5 of 8 patients with acute torsion. The advantages and limitations of the Doppler flow detector are presented.
