A total of 21 @entity1 (20 @entity1 and one @entity1 ) with @entity2885 ( @entity2885 ), treated in the Kaohsiung Veterans General Hospital during the period from 1991 through 1999 were included in this study. All of the @entity1 were @entity6 . The most common symptoms or signs were @entity221 /chills (80%) and costovertebral angle knocking @entity158 (71%). Diagnosis was confirmed by the presence of gas in the parenchyma or paranephric space on plain X-ray of the abdomen or computed tomography. The left kidney (11 cases, 52%) was more frequently affected than the right one (nine cases, 43%), and both kidneys were involved in one case. Obstruction of the corresponding renoureteral unit was found in 19% of the @entity1 , and @entity1290 was found in 23% of the @entity1 . One third of the @entity1 had type I @entity2885 , and two-thirds had type II @entity2885 . @entity526 was the most commonly isolated organism, accounting for 61%, 76%, and 47% of isolates from blood, urine, and aspirated pus culture respectively. Prompt control of blood sugar was begun and intravenous antibiotics were given. Drainage was performed in 71% of the @entity1 , and two @entity1 required nephrectomy because of poor control of the @entity281 . Overall survival was 72%. @entity2885 is a rare, life-threatening, suppurative @entity8 and perirenaL tissues. For successful management of @entity2885 , appropriate medical treatment should be initiated, and immediate nephrectomy or drainage should not be delayed.
