Objective：To investigate the epidemiological characters and treatment status of testicular torsion in Chongqing. Methods：Retrospective review and questionnaire survey were used to investigate 451 patients diagnosed with testicular torsion from January 2012 to December 2016 in 50 hospitals in Chongqing. The data were analyzed by descriptive statistic and Cochran-Armitage Trend test. Results：The epidemiological characters of the disease included that the disease mainly attacked individuals below 18 years old （65.9%），the onset usually occurred in winter（43.2%），the preliminary symptoms were scrotal pain（69.6%） and testis pain（25.7%），the ratio of left testis to right was 1.79∶1 and the torsion style was more common in the sheath（88.1%）. The misdiagnosis rate at ini－tial diagnosis was 32.8%. The lower of the doctor’s qualifications and institution’s level，the higher of the misdiagnosis and the longer of the duration from the onset of disease to clinic visit，the more opportunity of testicle loss and the differences were statistically signif－icant. The reasons for prolonged treatment mainly included the insufficient attention paid by patients and their families，as well as misdiagnosis by doctors at initial evaluation. Conclusion：There is a need to improve the diagnosis and therapy capabilities of doctors for testicular torsion，especially for those in primary hospitals and with junior degree. Meanwhile，enhancing the disease understanding of the public is also important.
