Staghorn calculi are complex renal stones that occupy the majority of the renal collecting system. These stones are associated with high morbidity and can lead to recurrent urinary tract infections, urosepsis, renal deterioration, and death if left untreated. Managing patients with staghorn calculi can be challenging.

What causes a staghorn calculus?

Staghorn calculi are most frequently composed of mixtures of magnesium ammonium phosphate (struvite) and calcium carbonate apatite; they are strongly associated with UTIs caused by organisms that produce the enzyme urease, which promotes the generation of ammonia and hydroxide from urea.

How serious is a staghorn kidney stone?

Over time, an untreated staghorn calculus is likely to destroy the kidney and/or cause life-threatening infections (sepsis). Complete removal of the stone is important in order to eradicate infection, relieve obstruction, prevent further stone growth, and preserve kidney function.

How do you treat staghorn calculi?

Generally, the gold standard treatment for staghorn stones is surgical with a view to achieve stone-free collecting system and preserve renal function. Percutaneous nephrolithotomy should be the recommended first-line treatment for staghorn stones.

Can you live with a staghorn kidney stone?

Due to the significant morbidity and potential mortality attributed to staghorn stones, prompt assessment and treatment is mandatory. Conversely, conservative treatment has been shown to carry a mortality rate of 28% in 10-year period and 36% risk of developing significant renal impairment.

Can staghorn calculi cause hematuria?

The majority of staghorn calculi are symptomatic: urinary infection, flanc pain, hematuria, urinary symptoms. The diagnosis can be performed by Plain abdominal radiography.

What problems are possible as a result of the staghorn stone?

If left untreated, staghorn calculi will destroy the kidney and may cause the death of the patient. Complications include azotemia, hydropyonephrosis, perinephric abscess, pyelonephritis (severe or end-stage), sepsis, and xanthogranulomatous pyelonephritis.

What are staghorn stones made of?

Most staghorn calculi are infection stones composed of struvite and/or carbonate apatite. Sometimes, cystine, uric acid, whewellite and brushite stones also assume a staghorn configuration when located in the kidney.
