Complete torsion with preserved flow. a Transverse color Doppler US image of both testes in a 13-year-old boy with 8 h of right-side acute pain shows oblique lie and globular enlargement of the right testis with preserved flow and surrounding small reactive hydrocele. There is a linear transducer artifact at mid-testis level. b Longitudinal color Doppler US image of the right testis shows a globular testis with intratesticular flow. During surgery, complete torsion was diagnosed with a 360° twist and bilateral bell clapper deformity. c Transverse gray-scale image of both testes in a 15-year-old boy with acute right testicular pain shows horizontal lie of the right testis. The asymptomatic left testis incidentally demonstrates a medially directed mediastinum testis and trace fluid in the tunica vaginalis. d Transverse color Doppler US image demonstrates preserved intratesticular flow thought to be symmetrical. Complete torsion of the right testis was diagnosed at surgery, and bilateral orchiopexy was performed post detorsion
