Abstract:

Emphysematous pyelonephritis （EPN） is a rare infectious disease of the renal parenchyma characterized by extensive necrosis of the renal parenchyma with gas accumulation in the renal parenchyma and perirenal tissues. Emphysematous cystitis is characterized by the presence of gas in and around the bladder wall，which is more rare and often associated with emphysematous pyelonephritis. We report a case of emphysematous pyelonephritis and emphysematous cystitis in a female patient. Despite the presence of septic shock，acute renal insufficiency，hyponatremia，and thrombocytopenia，the patient was cured and discharged after conservative treatment with percutaneous puncture drainage combined with medical treatment. Combined with the literature，we discuss the clinical manifestations，pathogenesis and treatment principles of this type of disease.

Key words: Emphysematous pyelonephritis, Emphysematous cystitis, Percutaneous drainage, Conservative management
