Abstract: Objective: To explore the diagnosis and treatment of testicular torsion so as to improve the efficacy treatment.Methods: The clinical data,including the onset,treatment and prognosis of 16 cases of testicular torsion were reviewed.The age of the patients ranged from 13-42 years.Results: Eleven cases had left side testicular torsion and 5 cases the right side.The elapse of time from onset to definite diagnosis was 2 h-8 d.The diagnosis of testicular torsion in 15 cases was based on color Doppler flow imaging(CDFI) and 1 case was verified by operation.All the 16 cases underwent acute operation.Twelve cases of testicles were removed for necrosis,and only 4 cases of testicles were salvaged by operative detorsion.Conclusions: Early diagnosis of testicular torsion is very important,and CDFI is reliable for diagnosis of testicular torsion.Immediately operation after admission is essential for salvage of the testicle.
