1/6. Bilateral emphysematous pyelonephritis caused by candida infection.Emphysematous pyelonephritis is a rare, often severe infection of one or both kidneys that is most often caused by bacterial infection. Surgical intervention is often necessary. We describe a case of a diabetic patient with bilateral emphysematous pyelonephritis caused by candida infection that was treated conservatively. Renal function recovered almost completely in spite of giving a potential nephrotoxic drug for 6 weeks.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/6. Adenovirus pyelonephritis in a pediatric renal transplant patient.Gross hematuria, graft pain, and rising serum creatinine are classic signs of acute rejection, obstruction, or bacterial pyelonephritis for patients with renal transplants. This presentation often prompts percutaneous renal allograft biopsy. If subsequent evaluation fails to show evidence of acute rejection, obstruction, or bacterial infection, viral etiologies should be considered. We report a 14-year-old Hispanic female with a living-related renal transplant who had gross hematuria, graft tenderness, and increased serum creatinine, but did not have evidence of acute rejection, obstruction, or bacterial pyelonephritis. To our knowledge, this is the first report of adenovirus pyelonephritis in a transplanted kidney of a pediatric patient, with isolation of adenovirus in the urine and in the allograft using immunocytochemical techniques.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
3/6. Severe emphysematous pyelonephritis on a horseshoe kidney.Emphysematous pyelonephritis is an acute bacterial infection responsible for a high mortality. It is characterized by bacterial gas production in the renal parenchyma, occurring in diabetic patients in most case. The gold standard treatment has always been surgery associated with antibiotic therapy. We report the case of a 58 year-old woman, with undocumented diabetes, who presented with emphysematous pyelonephritis complicated with septic shock and acute renal failure. Antibiotherapy alone was successful.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
4/6. Sonography of emphysematous pyelonephritis.Emphysematous pyelonephritis is a rare gas-producing bacterial infection of the renal parenchyma seen primarily in patients with diabetes mellitus. Sonographic findings in four patients with this disease are described. Sonographic features consist of multiple high-amplitude echoes within the renal parenchyma, renal sinus, and/or perirenal space accompanied by acoustic shadowing. Computed tomography confirmed bilateral involvement in one case. Plain abdominal radiographs demonstrated abnormal extraluminal gas in three of four cases. The role of sonography in diagnosis is discussed.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
5/6. Anaerobic bacterial infection and xanthogranulomatous pyelonephritis: a case report.A young man presented with a history of uncorrected ureteropelvic junction obstruction 18 months in duration and clinical acute pyelonephritis. Retrograde pyelography showed unilateral pyonephrosis and cultures of purulent drainage proximal to the ureteropelvic junction revealed predominantly anaerobic bacteria and no aerobic gram-negative bacilli. Subsequent nephrectomy established a diagnosis of xanthogranulomatous pyelonephritis. nephrectomy in combination with intensive antimicrobial therapy resulted in recovery. The contribution of anaerobic bacteria in the pathogenesis of xanthogranulomatous pyelonephritis is unknown. Anaerobic culture of urine and excised tissue in these patients may be indicated.- - - - - - - - - - ranking = 4keywords = bacterial infection (Clic here for more details about this article) |
6/6. Isolated renal mucormycosis: case report and review.The 15th reported case of isolated renal mucormycosis (infection of the kidney with fungus of the order mucorales, in the absence of infection elsewhere in the body) is presented. The patient was a 36-year-old human immunodeficiency virus-infected man, actively using iv drugs, who suffered 6 wk of flank pain and fever before diagnosis was made by percutaneous renal biopsy. He received 4 months of amphotericin b treatment, then no therapy for 6 months before dying with no evidence of mucormycosis. Isolated renal mucormycosis should be suspected in those with an underlying immunocompromising illness or history of iv drug use who have persistent flank pain and fever, but sterile urine cultures. Computed tomographic scanning with contrast should then be performed; findings of severe inflammation or bacterial infection, despite an indolent clinical course with sterile or nondiagnostic urine and blood cultures, are suggestive of isolated renal mucormycosis, and renal biopsy under computed tomographic guidance should be performed, despite the potential risk of disseminated infection. Although our patient was treated with amphotericin b alone, nephrectomy with or without amphotericin b therapy appears to be more likely to cure infection and relieve pain and constitutional symptoms.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
