OBJECTIVE: Emphysematous pyelonephritis (EPN) is an acute necrotizing infection of the kidney characterized by gas formation. In order to compare the outcome of nephrectomy and kidney-preserving procedures for the treatment of EPN we reviewed our experiences of EPN over the past 18 years.
MATERIAL AND METHODS: The medical records of 17 patients with EPN treated between October 1986 and September 2004 were retrospectively reviewed. Abdominal X-ray and/or CT were used as diagnostic methods.
RESULTS: Women outnumbered men (12 vs five), and all patients had diabetes. Obstruction of the corresponding reno-ureteral unit was found in one patient. Thirteen of the 17 patients (76%) had poorly controlled diabetes (hemoglobin A1c>7%). The diagnosis of EPN was confirmed by gas in the parenchymal or perinephric space as detected by abdominal X-ray or CT. Escherichia coli was the commonest organism present in urine cultures (52%), followed by Klebsiella pneumoniae (24%). Prompt efforts were made to control diabetes, and i.v. antibiotics were given. Nephrectomy was performed in 10 patients and nine patients survived (90% success rate). The success rate among those who received medical therapy only was 50% (2/4 patients). Percutaneous drainage was performed in three patients, two of whom survived (67% success rate). The overall mortality rate was 17.6% (3/17 patients).
CONCLUSIONS: Immediate nephrectomy with glycemic control measures and antibiotic administration is crucial for the successful treatment of EPN. However, in inoperable cases, percutaneous drainage can be an effective treatment option.
