Abstract:
Objective：To summarize the value of color Doppler in diagnosis of acute testicular torsion and testicular torsion in children.
Methods：Observe the two-dimensional ultrasound imaging and RI and spectrum changes of 26 cases of testicular torsion and 7 cases of appendage torsion, and compare with the operation;analyzed the diagnosis and differential diagnosis features.
Results：The imaging features of testicular forsion were obvicus decrease or disappearance of blood flow and enhanced echo of cordlike mass in the upper testicle. There was RI and spectrum change.The imaging features of appendage torsion were low echo of unsmooth mass, appearing round or round-like, and there were enlargement of testicle and increased colored blood flow signals.
Conclusion：Color Doppler has a high diagnostic rate of early diagnosis of acute testicular torsion and torsion of testicular appendages, which can guide the early treatment for incomplete testicular torsion.
