Abstract: Objective: To explore the early diagnosis and treatment of testicular torsion so as to improve the treatment efficacy. Methods: Color Doppler showed that the blood flow of the testis decreased obviously in 2 cases and disappeared in 11 cases. Thir teen cases of testicular torsion were treated by surgery. Results: All the 13 cases were proved to be testicular torsion by surgical exploration. Ten cases of testicular torsion occurred on the left side and 3 cases on the right. Necrosis was observed in 11 cases and the testis was removed; the testis of the other 2 cases changed red after reset and was reserved. Conclusions: Early diagnosis of testicular torsion is very important. External application of ice cap may be one of the ways to prevent necrosis of the reversed testis. Early surgical exploration is essential to retain the reversed testis.
