내과적 치료로 완치된 기종성 신우신염 2예

Emphysematous pyelonephritis is an uncommon, but life-threatening necrotiring infhmmation of renal parenchyme and perinephric tissue by gas-forming arganisms. This disease is encountered mainly in pa- tients with uncontrolled diahetes mellitus and/or urinary tract obstruction etc. Though the pathogenesis of this diseases is stiU poorly understood, radiographic demonstration of gas shadow in renal parenchyme and peri-nephric tissue establishes the diagnosis of emphysematous pyelone- phritis. The identification of this finding has been belie- ved to consider incision and drainage or nephrec- tomy in addition to medical treatment, because of high mortality rate of this disease in spite of vigo- rous medical management. We report two cases of emphysematous pyelone- phritis complicated in 62-year-old female and 48- year-old male patients with diahetes mellitus. Nephrectomies were not performed because of bilateral emphysematous pyelonephritis in one patient and of refusal of nephrectomy by the other patient. But patients were recovered completely on medical management.
