What are the differences between infected hydronephrosis and pyonephrosis?

Pyonephrosis is a suppurative infection of the upper urinary system which differs from infected hydronephrosis by the presence of frank pus. It is usually associated with parenchymal damage, chronic pyelonephritis and subsequent loss of kidney function [1].

What are the two types of pyelonephritis?

Pyelonephritis is an upper urinary tract infection. Pyelonephritis may be classified according to the duration of disease and etiology into 5 subtypes: acute uncomplicated, acute complicated, chronic, emphysematous, and xanthogranulomatous pyelonephritis.

Is pyelonephritis the same as hydronephrosis?

The most common complication of hydronephrosis is the development of a urinary tract infection (UTI).

Pyonephrosis—pus in the renal pelvis—results from urinary tract obstruction in the presence of pyelonephritis. Purulent exudate (inflammatory cells, infectious organisms, and necrotic, sloughed urothelium) collects in the hydronephrotic collecting system (“pus under pressure”) and forms an abscess.

What is the best treatment for pyelonephritis?

Outpatient oral antibiotic therapy with a fluoroquinolone is successful in most patients with mild uncomplicated pyelonephritis. Other effective alternatives include extended-spectrum penicillins, amoxicillin-clavulanate potassium, cephalosporins, and trimethoprim-sulfamethoxazole.

What is the difference between a UTI and pyelonephritis?

A urinary tract infection is inflammation of the bladder and/or the kidneys almost always caused by bacteria that moves up the urethra and into the bladder. If the bacteria stay in the bladder, this is a bladder infection. If the bacteria go up to the kidneys, it is called a kidney infection or pyelonephritis.

How is pyonephrosis diagnosis?

The diagnosis of pyonephrosis is suspected when the clinical symptoms of fever and flank pain are combined with the radiologic evidence of obstruction to the urinary tract. Sonography gives a prompt diagnosis of hydronephrosis, and needle puncture of the kidney yields pus and establishes the presence of pyonephrosis.

What is Xanthogranulomatous pyelonephritis?

Xanthogranulomatous pyelonephritis (XPN) is an unusual variant of chronic pyelonephritis. Most cases occur in the setting of obstruction due to infected renal stones [1-6].
