Abstract

PURPOSE
To assess the usefulness of percutaneous drainage of abscess in the treatment of emphysematous pyelonephritis.
MATERIALS AND METHODS
Ten cases of nine patients with emphysematous pyelonephritis were percutaneously drained. All were suffering from diabetes mellitus. The procedure was performed under fluoroscopic guidance in nine cases and US guidance in one case in which bilateral multiloculated abscesses were present in the perirenal spaces. The results were classified as cure, partial success, recurrence, or failure. The mean drainage period and complication were analyzed.
RESULTS
Eight cases were cured, and there was one partial success. In one case, who had diffuse renal parenchymal destruction without perirenal fluid collection, the treatment failed. The longest drainage period was 45 days, in a case of re-insertion due to incidental catheter removal ; the mean was 23 days. Bacteremia in one case was cured with antibiotic therapy which lasted two days.
CONCLUSION
In diabetic patients, percutaneous drainage of abscess is thought to be a safe and effective method for the treatment of emphysematous pyelonephritis, and is one that does not involve diffuse destruction of renal parenchyma.
