The majority of staghorn calculi are symptomatic, presenting with fever, haematuria, flank pain and potentially septicaemia and abscess formation. Staghorn calculi are composed of struvite chemically this is magnesium ammonium phosphate or MAP and are usually seen in the setting of recurrent urinary tract infection with urease-producing bacteria e. Proteus, Klebsiella, Pseudomonas and Enterobacter. Urease hydrolyses urea to ammonium with an increase in the urinary pH Uric acid and cystine are the underlying components of a minority of these calculi 5.

The vast majority of staghorn calculi are radiopaque and appear as branching calcific densities overlying the renal outline and may mimic an excretory phase intravenous pyelogram.

Lamination within the stone is common. The collecting system is filled with a densely calcified mass, producing marked posterior acoustic shadowing. Staghorn calculi are radiopaque and conform to the renal pelvis rneal 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.

If left untreated, staghorn calculi result in chronic infection and eventually may progress to xanthogranulomatous pyelonephritis 5.

There is usually little differential, provided intravenous contrast has not been administered. In the latter situation, the calcuo collecting system may be attributed to contrast rather than the calculus, especially when staghorn calculi are bilateral.
