[Two cases of testicular torsion diagnosed by the ultrasonic Doppler method].

Two cases of testicular torsion diagnosed with ultrasonic Doppler method are reported. Case 1. A 17-year-old male noticed pain and swelling of the right intrascrotal contents during sleeping and visited our clinic. A Doppler signal was obtained from the normal testicle, but not from the affected one. Bilateral orchiopexy was therefore done under the diagnosis of right testicular torsion. Case 2. A 20-year-old male visited our clinic with complaints of pain and swelling of the right intrascrotal contents. The ultrasonic Doppler method revealed no blood flow to the right testicle. After manual detorsion, pain improved and Doppler sound was audible. Bilateral prophylactic orchiopexy was performed later.
