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.
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.

Acute kidney injury (AKI), previously called acute renal failure (ARF), [1] [2] is a sudden decrease in kidney function that develops within seven days, [3] as shown by an increase in serum creatinine or a decrease in urine output, or both.
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).

Pyelonephritis is inflammation that results from a urinary tract infection that reaches the renal pelvis of the kidney. [6] Lupus nephritis is inflammation of the kidney caused by systemic lupus erythematosus (SLE), a disease of the immune system. [7] Athletic nephritis is nephritis resulting from strenuous exercise.

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.

Acute kidney injury (AKI), previously called acute renal failure (ARF), [12] [13] is a rapidly progressive loss of renal function, [14] generally characterized by oliguria (decreased urine production, quantified as less than 400 mL per day in adults, [15] less than 0.5 mL/kg/h in children or less than 1 mL/kg/h in infants); and fluid and ...
