Abstract:
Objective To establish a predictive model of testicular torsion according to the clinical data of pediatric patients with acute scrotum.Methods Retrospective study was performed to analyze medical records of 118 pediatric patients with acute scrotum.A case-control study was conducted,the case group included the patients with testicular torsion and the control group included the patients without testicular torsion.Data of patients including physical signs and laboratory tests related to testicular torsion were assessed by univariate analysis through Chi-square test or t test.All factors which had statistical significance in the univariate analysis were used as independent variables for multivariate Logistic analysis to establish a predictive model of pediatric testicular torsion.Results There were 54 patients in the case group and 64 patients in the control group.Vanishment of cremaster reflex,duration of pain,fever,urine positive and fading away of color Doppler flow imaging (CDFI) were independent predictors of pediatric testicular torsion (all P ＜ 0.05),and the OR values were 4.330,0.888,0.229,0.107 and 4.408,respectively.The predictive model of testicular torsion in pediatric patients was as follows:In [P / (1-P)] =2.307 + 1.466 × vanishment of cremaster reflex-0.119 × duration of pain-1.476 × fever-2.235 × urine positive + 1.484 × CDFI.Conclusions The Logistic regression model,which takes into account vanishment of cremaster reflex,duration of pain,fever,urine positive and CDFI,can be used to predict the risk factors of pediatric testicular torsion to provide a basis of surgical exploration.
