Background
Fournier’s gangrene (FG) is a life-threatening infection of the genital, perineal, and perianal regions with a morbidity range between 3 and 67%. Our aim is to report our experience in treatment of FG and to assess whether three different scoring systems can accurately predict mortality and morbidity in FG patients.
Methods
All patients that were treated for FG at the Department of Urology of the University Hospital Basel between June 2012 and March 2017 were included and assessed retrospectively by chart review. Furthermore, we calculated Fournier’s Gangrene Severity Index (FGSI), the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC), and the neutrophil–lymphocyte ratio (NLR) in every patient and assessed whether those scores correlate with the patients’ morbidity and mortality.
Results
Twenty patients were included, with a median (IQR) age of 66 (46–73) years. Fifteen of twenty (75%) patients required treatment on an intensive care unit, and three died (mortality rate: 15%). The mean FGSI, LRINEC, and NLR scores were 13.0, 9.3, and 45.3 for non-survivors and 7.7, 6.5, and 26 for survivors, respectively. None of the risk scores correlated significantly with mortality; however, all three significantly correlated with infection- and surgically-induced morbidity.
Conclusions
In our series, Fournier’s gangrene was associated with a mortality rate of 15% despite maximum multidisciplinary therapy at a specialized center. All risk scores were able to predict the morbidity of the disease in terms of local extent and the required surgical measures.
