Acute focal bacterial nephritis is a part of urinary tract infection and a special form of acute pyelonephritis. In most cases, it is treated well by antimicrobial therapy without severe complications. Unusual cases have been reported that renal failure and or chronic granulomatous interstitial nephritis was combined with acute focal bacterial nephritis. We describe a case of acute reanl failure complicated by acute focal bacterial nephritis in 30-year-old male. He was admitted to this hospital owing to fever, chilling, right flank pain. On admission, BUN and creatinine were 29 mg/dl, 1.8 mg/dl. Urinalysis showed leukocyturia, & bactriuria. Urine culture revealed E. coli over us. Abdominal CT and ultrasonography was represented focal hypodense area and diffuse renal enlargement so we could diagnose acute focal bacterial nephritis. The patient was improved with antimicrobial therapy and hydration. In conclusion, this case shows the possibility that unusual complication such as acute reanl failure can be happensed in acute focal bacterial nephritis in continum with acute pyelonephritis
