AbstractA 74-year-old woman with diabetes mellitus had a high fever, and was treated with antibiotics and insulin in another hospital. She was referred to our department, because CT scan showed the right hydronephrosis and the abnormal gas shadow in the right renal calyces. Ureteral catheterization was performed on the right side and cloudy urine was drained. Urine culture yielded E. coli. Since submucosal emphysematous changes were demonstrated in the bladder mucosa by cystoscopy, she was diagnosed with emphysematous pyelonephritis with emphysematous cystitis associated with diabetes mellitus. Administration of antibiotics and insulin and the ureteral catheter drainage improved her condition immediately. Abnormal gas shadow on CT scan and submucosal emphysema on cystoscopy disappeared. We reviewed 110 cases of emphysematous pyelonephritis and 23 cases of emphysematous cystitis including our case in Japan, and report their clinical characteristics.
