Testicular Torsion in Children. Diagnostic and Prognostic Potential of Ultrasonography

Introduction: Testicular torsion is the most urgent case in pediatric andrology that requires emergency care due to high sensitivity of testicular tissue hypoxia. Objective: To determine statistically significant parameters indicating diagnostic significance some ultrasonographic symptoms children. Materials and methods: Ultrasonography was performed 202 children with (main group) 449 patients (control aged from 2 months 17 years 11 28 days. During statistical processing we determined mean values, their standard deviation, sampling errors, differences correlation coefficient did ROC analysis. For an objective assessment shape, implemented rounding – k o = (testicular length thickness) / parameter Δk calculated as difference between for affected side contralateral one. Results discussion: more common above 12 age (84.7%). The 0.160 ± 0.007 group 0.037±0.003 control (t 16.92, p >> .001). analysis proved be highly informative: AUC 0.886. 0.130 0.008 favorable treatment outcomes 0.19 0.01 (p < 0.001) those unfavorable outcomes. In cases (71), whirlpool sign visualized preserved blood flow. such a case, probability outcome 74.6%. visualization significantly less (31 cases) without Doppler ultrasonography; were achieved 54.8%. Of 22 undetected sign, possible only 40.9%. Conclusions: can used auxiliary criterion early diagnosis torsion. With 0.08, respect 79.2%, specificity 85.7%. 0.16, almost 100% 45.0% decrease sensitivity. Whirlpool detection using color ultrasonography positive prognostic factor.
