Patient transfer influences the prognosis of pediatric patients operated for testicular torsion: a single-center experience

BACKGROUND: Testicular torsion (TT) remains an emerging issue for pediatric patients. This study’s objective was to determine risk factors of TT outcomes in the Chinese pediatric cohort from a single center. METHODS: We performed a retrospective cohort study of patients who met the inclusion criteria in our center from 2013 to 2018. Clinical demographics, and TT-related data, including laterality, torsion degree, torsion direction, position to the cavity of tunica vaginalis, enorchia, and outcomes, were reviewed and extracted from medical charts and databases. Statistical analysis was conducted to compare and figure out the risk factors of TT outcomes. RESULTS: A total of 84 pediatric patients were enrolled in this study. Among these variables, age, duration of symptoms, and the patient transfer were significantly associated with the outcomes of TT (P<0.005). Patients transferred from other medical facilities underwent more orchiectomy than those without transfer (univariate analysis, P<0.0001; multivariate analysis, P=0.001). No difference was found in other variables between patients with or without transfer (P>0.05). Moreover, transferred patients tended to show worse testicular function. CONCLUSIONS: We have reported that age, duration of symptoms, and patient transfer were three significant risk factors in this cohort. Patients with transfer tended to suffer from more orchiectomy and worse prognosis of TT.
