Acute pyelonephritis is an exudative purulent localized inflammation of the renal pelvis (collecting system) and kidney. The kidney parenchyma presents in the interstitium abscesses (suppurative necrosis ), consisting in purulent exudate (pus): neutrophils, fibrin, cell debris and central germ colonies (hematoxylinophils).
It is generally not recommended to perform routine radiographic imaging on patients who have simple urinary tract infections. When patients do not improve quickly with appropriate antibiotics , however, appropriate radiographic studies help diagnose pyonephrosis, emphysematous pyelonephritis, and renal and/or perirenal abscesses.
Urinary tract infection in pediatric patients is a significant clinical issue, affecting approximately 7% of fevered infants and children. [43] If left untreated, the infection can ascend from the bladder to the kidneys, resulting in acute pyelonephritis, which leads to hypertension, kidney scarring, and end-stage kidney disease. [44]

The causes of acute kidney injury are commonly categorized into prerenal, intrinsic, and postrenal. Acute kidney injury occurs in up to 30% of patients following cardiac surgery. [22] Mortality increases by 60-80% in post-cardiopulmonary bypass patients who go on to require renal replacement therapy.
Patients who have experienced an acute renal infarction usually report sudden onset flank pain, which is often accompanied by fever, nausea, and vomiting. [ 4 ] The primary causes of renal infarction are hypercoagulable conditions, renal artery damage (usually brought on by arterial dissection ), and cardioembolic illness.
Fosfomycin can be used as an effective treatment for both UTIs and complicated UTIs including acute pyelonephritis. [87] The standard regimen for complicated UTIs is an oral 3g dose administered once every 48 or 72 hours for a total of 3 doses or a 6 grams every 8 hours for 7 days to 14 days when fosfomycin is given in IV form.

Interstitial nephritis is uncommon (<1% incidence) in patients without any symptoms but occurs in about 10-15% of hospitalized patients with acute kidney injury of unknown cause. [2] While it can occur in patients of all ages, it is more common in elderly patients, perhaps due to increased exposure to drugs and other triggering causes. [2]
