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).
For acute cystitis and pyelonephritis in pregnant women, empiric antibiotic treatment is often initiated. Commonly used antibiotics for uncomplicated cystitis include amoxicillin-clavulanate and fosfomycin, while parenteral beta-lactams are preferred for acute pyelonephritis. These options are chosen because they are considered safer in ...
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.
