Yeast perinephric abscess: report of a case and review.

We report a case of yeast perinephric abscess and review 11 other published cases. This rare entity occurs primarily in patients who have diabetes mellitus, who have recently undergone surgery, or who have urinary tract obstruction. The clinical illness is often subacute or chronic with nonspecific symptoms. Candida and Torulopsis species are the reported etiologic agents. Successful therapy usually consists of percutaneous or surgical drainage of the abscess. Overall mortality is 25%; however, no patient in this series died as a direct result of perinephric infection.
