Renal abscess in healthy children: report of three cases.

We report three cases of renal abscess in otherwise healthy boys. One had a history of blunt trauma and two of antecedent skin infection. All presented with flank pain and fever. Urine and blood cultures were sterile. The diagnosis was made using ultrasound and computerized axial tomography. The first patient had recurrent renal abscess, following surgery and a short course of antibiotics. Eventually all responded well to long-term antibiotics only.
