[1st experiences with the ultrasonic-Doppler-method in the diagnosis of testicular torsion].

In some cases the differential diagnosis of the torsion of the testicles may be difficult also for the experienced clinician. It is reported on a new method of the delimitation of the torsion of the testicles compared with inflammatory changes of the testicles and the epididymis. By means of the ultrasound-Doppler-method the blood supply of the vasa spermatica is registered. Missing Doppler-signals in the direct measurement above the spermatic cord in comparison to the collateral side are typical for a complete torsion of the testicles.
