Staphylococcus Aureus
Community-acquired methicillin-resistant Staphylococcus aureus as a cause of rapidly progressing pyelonephritis with pyonephrosis, necessitating emergent nephrectomy. Am J Med Sci. 2009 Sep. 338(3):233-5. [Medline]. [emedicine.medscape.com]
Treatment
Treatment Controversies and Considerations Treatment of infections occurring from pyelonephritis [42] and pyonephrosis is changing rapidly and dramatically. [emedicine.medscape.com]
Prognosis
The prognosis of pyonephrosis is good in most patients who receive prompt diagnosis and treatment. [emedicine.medscape.com]
Etiology
Etiology Upper urinary tract infection in combination with obstruction and hydronephrosis may lead to pyonephrosis. [emedicine.medscape.com]
Epidemiology
Epidemiology Pyonephrosis is uncommon in adults and rare in children, and it is thought to be extremely rare in neonates. [emedicine.medscape.com]
Prevention
The decreased function of the affected kidney that accompanies active infection typically prevents visualization on contrast studies. [emedicine.medscape.com]
