What is emphysematous cystitis?

See answer: Emphysematous cysitis (ec) is a rare entity characterized by pockets of gas in and around the bladder wall produced by bacterial or fungal infection and fermentation. Most commonly seen in diabetics. Prompt dx, controlling one's sugars if a diabetic, insuring adequate baldder emptying, and being treated with the correct antibiotic based on urine culture (iv and/or oral) usually results in cure.
