Abstract
BackgroundWe aimed to assess the diagnostic value of hematologic parameters in the differential diagnosis of testicular torsion and epididymitis within and after the golden time.MethodsWe retrospectively reviewed the records of 250 patients aged <25 years who were diagnosed with epididymitis (n=119) or testicular torsion (n=131). The characteristics and hematologic parameters of patients in the two groups were analyzed. Receiver operating characteristic (ROC) curves were used to assess the validity of hematologic parameters as differential diagnostic tools with respect to the golden time (defined as 6 h of symptom duration). Further, we evaluated the predictive factors associated with orchiectomy in patients with testicular torsion.ResultsThe mean patient age was 14.4 years. Among patients with testicular torsion, 91.40% (53 of 58) underwent detorsion and orchiopexy within the golden time, whereas only 27.40% (20 of 73) of the affected testes were preserved after the golden time. Within the golden time, mean platelet volume (MPV) seemed to be the most valuable hematologic parameter [area under the curve (AUC) 0.855, 95% confidence interval (CI): 0.778–0.932]. In a multivariate analysis, symptom duration (symptoms beyond the golden time) was associated with orchiectomy in patients with testicular torsion.ConclusionsMPV showed the greatest hematologic value in the early stage of testicular torsion and epididymitis, suggesting its potential use for the differential diagnosis of these two conditions within the golden time.
