Emphysematous pyelonephritis with gas in inferior vena cava

摘要

Emphysematous pyelonephritis (EPN) is a progressive necrotizing infection of the renal parenchyma, collecting system and perinephric tissue. A 36-year female with uncontrolled diabetes, presented with left emphysematous pyelonephritis, with air in the infra-hepatic inferior vena cava (IVC). She was hydrated, treated with intravenous antibiotics, insulin. Percutaneous nephrostomy with Double J stenting was done in modified supine position. Patient was discharged with nephrostomy. Two weeks later, flexible ureterorenoscopy was done and obstructing papillary necrosis removed. Pneumo-vena cava due to emphysematous pyelonephritis is quite rare and careful evaluation is required. Prompt intervention is life saving and obviates the need for nephrectomy.
