[SUCCESSFUL TREATMENT OF SEVERE EMPHYSEMATOUS CYSTITIS USING RETROPENITONEAL DRAINAGE: A CASE REPORT].

Emphysematous cystitis is a rare disease involving infection caused by gas-producing bacteria is characterized by air storage in the bladder wall and lumen. Approximately 90% of the affected cases are treated using medical therapy alone, and approximately 10% require combined surgical treatment. Here we report a case of emphysematous cystitis with septic shock that could be treated using multimodal therapy with retroperitoneal drainage. A 76-year-old woman was hospitalized at a nearby hospital owing to lumbar compression fracture. She was transferred to our hospital owing to altered consciousness and low blood pressure. She was diagnosed with emphysematous cystitis, and conservative treatment was performed using an indwelling bladder catheter and by administering antibiotics or vasopressors. The patient had septic shock; hence, retroperitoneal drainage was performed. After surgery, the patient's general condition improved. In this study, we review the characteristics of five cases of emphysematous cystitis requiring surgical treatment in Japan.
