Pyelonephritis is distressful condition requiring emergent medical management. Most individuals who are treated adequately with [[antibiotics]] do not have complications. A surgical management with removal of stone or obstructing [[tumor]] may sometimes be required to prevent complications and prevent obstructive pyelonephritis and stop the course of chronic pyelonephritis. The most common complication of pyelonephritis is recurrent [[Infection|infections]]. Most episodes of pyelonephritis are uncomplicated and are easily treatable. The prognosis of pyelonephritis varies depending on the type of pyelonephritis and on the timing and duration of treatment. The mortality in case of [[UTI]] is between 5% to 33%.

If left untreated, Pyelonephritis can lead to papillary necrosis and ultimately leading to scaring of the kidneys. This scaring can cause [[Renal failure]] in some cases. Abscess formation in or around the renal tissue is also possible. Pyelonephritis can prove fatal in some cases without treatment. The following factors influence the prevalance of pathogens in the kidneys: <ref name="pmid12767958">{{cite journal| author=Efstathiou SP, Pefanis AV, Tsioulos DI, Zacharos ID, Tsiakou AG, Mitromaras AG et al.| title=Acute pyelonephritis in adults: prediction of mortality and failure of treatment. | journal=Arch Intern Med | year= 2003 | volume= 163 | issue= 10 | pages= 1206-12 | pmid=12767958 | doi=10.1001/archinte.163.10.1206 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=12767958  }} </ref>

Overview

Pyelonephritis is distressful condition requiring emergent medical management. Most individuals who are treated adequately with antibiotics do not have complications. A surgical management with removal of stone or obstructing tumor may sometimes be required to prevent complications and prevent obstructive pyelonephritis and stop the course of chronic pyelonephritis. The most common complication of pyelonephritis is recurrent infections. Most episodes of pyelonephritis are uncomplicated and are easily treatable. The prognosis of pyelonephritis varies depending on the type of pyelonephritis and on the timing and duration of treatment. The mortality in case of UTI is between 5% to 33%.

Natural History

If left untreated, Pyelonephritis can lead to papillary necrosis and ultimately leading to scarring of the kidneys. This scarring can cause renal failure in some cases. Abscess formation in or around the renal tissue is also possible. Pyelonephritis can prove fatal in some cases without treatment. The following factors influence the prevalence of pathogens in the kidneys:[1][2][3][4]

Complications

Pyelonephritis can lead to the following complications:[1][5][6]

Life threatening complications

Other complications

Prognosis

  • Most episodes of pyelonephritis are uncomplicated and are easily treatable. The prognosis of pyelonephritis varies depending on the type of pyelonephritis and on the timing and duration of treatment.[4]
