RESUMO
BACKGROUND: A 54-year-old nondiabetic male presented with high fever, vague lower abdominal pain and leakage of urine around his long-standing suprapubic catheter. Examination revealed pyrexia and tenderness in the right renal angle. White cell count was 22.8 x 10(9)/l. Plain abdominal X-ray showed calculi in the right kidney, ureter and bladder. Intravenous pyelogram showed gas confined to the right upper renal pelvis and perinephric space. INVESTIGATIONS: Urine and blood cultures, plain abdominal X-ray, intravenous pyelogram, abdominal ultrasound, MAG3 renogram and histopathology. DIAGNOSIS: Emphysematous pyelonephritis: class 2 or type 1. Escherichia coli was isolated from urine obtained by endoscopic drainage. MANAGEMENT: Endoscopic drainage of pus and simple nephrectomy.
