Eight patients with renal abscess were seen in a 15-year period. The patients' ages ranged from 3 to 15 years with a mean of 6.5 years. Included were 7 female children, five of whom were Aboriginal, and 1 male child. ⋯ In 5 cases the infecting organism was penicillinase-producing Staphylococcus aureus and, in 2 cases, Escherichia coli was isolated. It is concluded that the diagnosis of renal abscess should be considered in patients with a febrile septicaemic illness, particularly in Aboriginal female children. Ultrasonography is recommended as the investigation of choice which can also be used to establish percutaneous drainage, thus avoiding surgery.
