ステップ 1 · Is necrotizing fasciitis suspected
Perineal/genital infection + systemic toxicity/crepitus — necrotizing fasciitis suspected?
💡 Necrotizing fasciitis of the perineal/genital/perianal region, a urologic emergency, mortality ~20–40%; usually mixed aerobic-anaerobic synergistic infection. Risk factors: diabetes (most common), alcohol abuse, immunosuppression, elderly men; arising from perianal/rectal abscess, GU infection. Early signs non-specific (fever, scrotal edema, pain out of proportion to signs) → rapid deterioration: dusky skin, crepitus (subcutaneous gas), foul dishwater-like pus, necrosis, sepsis.
