BACKGROUND: Emphysematous pyelonephritis is a rare and severe urinary tract infection that is potentially life-threatening and easily progresses to septic shock. In this report, we present a unique case of emphysematous pyelonephritis caused by Raoultella ornithinolytica.
CASE PRESENTATION: An 86-year-old man presented with severe back pain of 3 days' duration. He had a history of hypertension and diabetes for more than 20 years, and his infection indicators and serum creatinine were elevated. Abdominal computed tomography revealed an abnormal gas shadow around his right kidney and the anterior edge of his right psoas muscle. Consequently, he was initially diagnosed with emphysematous pyelonephritis. There was no evidence of nephrolithiasis or other anatomical or structural abnormalities that could have precipitated this focal renal infection. Both blood and drainage fluid cultures revealed R. ornithinolytica. After early anti-infection treatment, percutaneous drainage and moderate control of blood glucose, the patient gradually recovered.
CONCLUSIONS: Emphysematous pyelonephritis caused by R. ornithinolytica is rare but has a high drug resistance rate potentially and may cause severe infections. Early diagnosis, prompt use of antibiotics that are sensitive to the organism, and decompression drainage could be the key to treatment.
