Three Cases of Acute Focal Bacterial Nephritis

ABSTRACT

Acute focal bacterial nephritis(AFBN) is an unusual form of localized renal infection, which has various imaging findings and should be distinguished from abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a CT or sonographic confirmation. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report three cases of AFBN with urinary tract infection in an 11-month-old, 9-month-old female and 8-month-old male patients, respectively. The confirmative diagnosis was done by localized intrarenal solid mass lesion by sonography. They were treated with intravenous and oral antibiotics for 6, 4 and 2weeks, respectively. Follow-up urinalysis, urine culture and sonographic finding were normal after treatment.
