Abstract
Purpose: Testicular torsion (TT) is a serious surgical emergency. Prompt diagnosis and treatment of TT are essential to improve the incidence of salvaged testes. The aim of this study was to evaluate the historical features, physical examination findings, laboratory tests, and ultrasound examinations in children with TT, as well as to identify the predictors of testicular salvage in children. Materials and Methods: We retrospectively reviewed the records of 136 males who presented with TT to our institution. Clinical findings, physical examinations, laboratory data, color Doppler ultrasound findings, operating results, and the results of follow-up were collected and analyzed. Patients with neonatal torsion, negative scrotal exploration, or testicular appendix torsion were excluded. A multivariable logistic regression model was used to identify predictors of testicular salvage. Receiver operator characteristics analyses were performed to determine the probability of a non-salvageable torsed testis based on time and degree of twisting. Results: A total of 136 children with TT were identified. Patients were aged from 1 to 16 years, with a mean age of 9.7 years (median, 12; range, 1–16 years). The peak incidences of TT were found between ages of 12 and 14 years. Acute TT is significantly more common in the winter. Testicular salvage occurred in 49 (36%) cases. Of the 49 cases of testicular salvage, 5 patients developed subsequent testicular atrophy. Cutoff values of 13.5 h and 530 degrees of torsion would provide sensitivities of 96 and 61%, with specificity of 80 and 70%, respectively. Multivariate analysis showed that time to surgery and degree of testicular twist were correlated with the risk of a non-salvageable testis. Conclusions: Testicular salvage can be predicted by the duration of symptoms along with degree of twisting. Early scrotal exploration based on careful physical examination decreases the risk of misdiagnosis of spermatic cord torsion. A certain percentage of children with TT presenting with lower abdominal pain should have their testicles checked to make sure that they do not have torsion, especially those visitors in cold season.
