The value of color Doppler ultrasound in the predicting of the viability after testicular torsion

Objective: To explore the value of color Doppler ultrasound in the predicting of the viability after testicular torsion. Methods: The clinical data of color Doppler ultrasound flow imaging in 16 cases with testicular torsion were retrospectively analyzed. The testicular torsion were divided into type a,b,c and d according to the color Doppler ultrasound flow imaging before operation. According to intraoperative testicular torsion,testicular viability was divided into level. A,B,C and D The testis with level A to C viability could be saved,the testis with level D viability could not be saved. The testicular viability during the period of following-up could be divided into grade Ⅰ to Ⅲ,the testis with grade Ⅰ and Ⅱ survived,and grade Ⅲ atrophied. Results: Among 16 cases with testicular torsion,the testis in 10 cases and 6 cases were restored and resected,respectively. Nine cases with restoration survived,their preoperative ultrasonography included type a in 3 cases,type b in 2 cases and type c in 4 cases,their intraoperative testicular activity included level A in 1 case,level B in 3 cases and level C in 5 cases,their forward testicular viability included grade Ⅰin 2 cases and Ⅱ grade in 7 cases. One testis with restoration atrophied,its preoperative ultrasonography,intraoperative testicular activity and forward testicular viability were type d,level D and grade Ⅲ,respectively. Amony 6 cases with testicular resection,the type c and d of preoperative ultrasonography were 1 case and 5 cases,respectively,their intraoperative testicular activity were level D. Conclusions: Color Doppler ultrasound of testicular torsion can predict the testis viability,which provide an important reference for clinical surgery program,and is the key to rescue testicular torsion and improve its viability.
