Abstract
BACKGROUND: To predict testicular involvement in patients diagnosed with Fournier's gangrene (FG) using the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score and the site other than lower limb (SIARI) score. METHODS: The medical records of 51 patients operated for FG in our clinic between December 2012 and April 2022 were evaluated retrospectively in this study. Patients' demographics, and laboratory test results were compared with the testisticular involvement status. Patients with testisticular involvement (n = 10) were compared with patients without testicular involvement (n = 41). The SIARI score at initial admission was analysed using logistic regression analyses for its performance in predicting testicular involvement with FG. Receiver operating characteristics (ROC) curves and the area under the receiver operating characteristic curve (AUROC) were used to evaluate its discriminating ability. RESULTS: The SIARI score had modest performance for diagnosing testicular involvement in FG patients, with ROC analysis showing an AUROC value of 0.83 (p < 0.001). With a SIARI cut-off score of ≥ 3, the sensitivity was 90% and the specificity was 68%. For a SIARI cut-off score of ≥ 5, the sensitivity was 40% and the specificity was 97%. CONCLUSIONS: The ability of the SIARI score to discriminate FG with testicular involvement is modest. The SIARI score should be employed cautiously as a routine diagnostic tool for the prediction of testicular involvement in FG at the initial admission. More research is needed to develop a better understanding of the relationship between the SIARI score and testicular involvement in FG.
