Renal abscesses present simiarly to pyelonephritis, but often may be more severely symptomatic. The formation of renal abscesses is thought to result from insufficiently treated pyelonephritis or hematogenous dissemination of infection. Patients with diabetes are at increased risk of renal abscess development. Pain from a renal abscess is thought to result not only from local tissue inflammation, but also parenchymal edema that causes the renal capsult to stretch.
