Objective:
Evaluate the origin of Fournier gangrene (FG) as a prognostic factor of morbidity and mortality.
Material And Methods:
Patients who came to our clinic with a diagnosis of FG from 2010 to 2017 were included retrospectively. Patients were categorized depending on the origin of the infection. Three severity factors were determined in each group: days of hospital stay, the FG severity index, and mortality. Logistic regression test was performed to analyze the data.
Results:
Of the 130 patients evaluated, the origin was established in 121 based on the clinical history and radiological and surgical findings. Thirty-five patients had an intestinal origin with a mortality of 20.68%, 46 patients had a testicular origin with a mortality of 2.22%, 12 patients had a urinary origin with a mortality of 0%, and 28 patients with a cutaneous origin with a mortality of 16.6%. The testicular origin was the most frequent (38%) in addition to presenting a lower hospital stay, a lower FG severity index, and a lower mortality than those with an intestinal origin (P=.022).
Conclusions:
The origin of the infection has a significant prognostic value in the mortality of the patient.
