Staghorn calculi are composed of struvite (magnesium ammonium phosphate) and are usually seen in the setting of recurrent urinary tract infection with urease producing bacteria (e.g. Proteus, Klebsiella, Pseudomonas and Enterobacter).Urease hydrolyses urea to ammonium and increase in the urinary pH 3-5.taghorn calculi are radiopaque and conform to the renal pelvis and calyces, which are often to some degree dilated. When viewed on bone windows they have a laminated appearance, due to alternating bands of magnesium ammonium phosphate and calcium phosphate 5.
