    BackgroundFournier gangrene (FG) is a rapidly progressive soft-tissue necrosis that may be life-threating unless aggressive treatment is applied immediately. FG severity index was described first by Laor et al. to predict mortality rate but there are few studies on the prognostic significance of FG severity index and especially the microbial agents isolated from debridement on patient prognosis. Hence, in the present study, it has been aimed to investigate the significance of FG severity index and infective agents on hospital stay, frequency of debridement, and mortality.MethodsThirty-four patients who were operated with the diagnosis of FG between January 2013 and January 2018 were retrospectively analyzed. FG severity index scores in admission were calculated and patient was divided into two groups according to the cutoff value of FG severity index. Patient was categorized according to the microbial agents isolated from debridement cultures. Patient characteristics were compared between the group of survivors and non-survivors. The effect of FG severity index and microbial agent type on hospital stay, frequency of debridement, and mortality was analyzed.ResultsIt was found that mortality rate was significantly higher in the group of FG severity index score >9 than the other group (100% vs. 6.7%; p=0.001>) and it was observed that FG severity index had predicted the mortality rate as 100% and survival rate as 93.3% but there were no significant relation between FG severity index with the frequency of debridement and hospital stay. The mortality rate (50% vs. 4.2%; p=0.005) and frequency of debridement (3.10±0.73 vs. 2.00±0.72; p=0.001) were significantly higher in the subgroup of patient infected with clostridial and atypical agents.ConclusionFG severity index was found to be insufficient in determining the frequency of debridement and the hospital stay but it accurately predicts the rates of mortality and survival. The patients who were infected with clostridial and atypical agents are more likely to develop mortality and tend to be need more aggressive surgical interventions than the others.
