Abstract:
Objective:To find out predictors of the testicular ischemia caused by incarcerated inguinal hernia and evaluate the ischemic injury of the testis more accurately, which can indicate testicle exploration in time or prevent unnecessary testicle exploration.Methods:Pediatric patients (median: 9 months) undergoing operation of unilateral incarcerated inguinal hernia and ipsilateral testicular exploration from 1 Jul. 2013 to 30 Jun. 2019 were retrospectively investigated. Age at surgery, incarcerate duration, degree of intestinal and testicular injury, times of manual reduction and preoperative ultrasound data were collected. Statistical analysis was performed by SAS 9.4 (Copyright ? 2016 SAS Institute Inc.Cary, NC, USA) .Results:460 patients (median: 9 months) , of which 57 (12.39%) (median: 1.4 months, interquartile range 0.8-10.7 months) had severe testicular injury, and their average incarceration time was (23.9±9.3) h. Univariate logistic regression revealed that increased times of manual reduction, ultrasound scores, incarcerate duration and degree of intestinal injury were positively correlated with the degree of testicular ischemia, while age at surgery was negatively correlated with the degree of testicular ischemia ( P<0.05) . A model for calculating the probability of severe testicular ischemia injury was established: P= through multivariate analysis with backward stepwise logistic regression and 10-fold cross-validation was used for preliminary verification of the model. Conclusion:This study provides a relative reliable model to predict the risk of irreversible testicular ischemia due to incarcerated inguinal hernia using readily available clinical characteristics in young pediatrics with testicular ischemia.
