title: Renal actinomycosis associated with a duodenorenal fistula caused by foreign body.
abstract: We are reporting a case of a rare renal actinomycosis in a 12-year-old mentally-retarded girl. Proteinuria and hemopyuria were pointed out one year before the operation by an annual medical check-up and IVP subsequently performed showed foreign bodies at the upper pole of the right kidney. The patient continued to have pyuria and right nephrectomy was performed. There was a fistula between the duodenum and the upper portion of the right kidney. Foreign bodies (two bobby pins) were found in the kidney. Subsequent pathologic examination of the resected kidney revealed an actinomycotic lesion.
