Abstract:
Objective: To analyze the relationship between perirenal fat thickness (PFT) and the severity of closed renal trauma，so as to provide reference for treatment selection and prediction of the severity of injury. Methods: The clinical data of 73 patients with unilateral closed renal trauma due to traffic accidents treated in our hospital during Jan.2012 and Dec.2022 were reviewed.According to American Association for the Surgery of Trauma (AAST)，the patients were classified into mild group (AAST Ⅰ-Ⅲ) and severe group (AAST Ⅳ-Ⅴ).The PFT of the healthy kidneys during injury was measured on the PACS software CT images，and the correlation between PFT and severity of injury was analyzed using logistic regression.The difference in PFT between patients across treatment modalities using one-way ANOVA. Results: The mean age of patients was (44.7±17.1) years.There were 16 patients (21.9%) in the severe group and 57 (78.1%) in the mild group，the mean PFT being (5.5±1.9) mm.The severe group had significantly lower PFT than the mild group \[(4.4±1.4) mm vs. (5.8±2.0) mm，P=0.003\].After age，gender，body mass index，diabetes，protective devices and complicated organ injuries were adjusted，multivariable logistic analysis indicated that increased PFT was associated with lower risk of severe injury (OR=0.628，95% CI：0.430-0.918，P=0.016).One-way ANOVA analysis showed statistically significant differences in PFT among patients with conservative，interventional and surgical treatment options \[（5.8±2.0）mm vs.（4.4±1.5）mm vs.（4.5±1.1）mm，P=0.034\]. Conclusion: PFT，which is closely related to the severity of closed renal trauma，is a reliable indicator to predict the severity of injury and the choice of treatments.
