![]() ![]() If you have an abnormality of your urinary tracts, such as one that affects its shape or structure.If you’ve had a urinary tract infection caused by bacteria in the past.Though anyone can develop staghorn calculi, there are several risk factors that make you more likely to get them. What is increase the risk of Staghorn Renal Calculi (kidney stones)? The NKF says there are four major causes of kidney stones: not drinking enough water, getting too much calcium from food and supplements, having too much oxalate in your diet, and having a buildup of uric acid due to gout or chemotherapy. READ THIS: What is a uric acid blood test? What exactly causes them? If you have a staghorn stone and your symptoms get worse, contact your doctor immediately so treatment can begin as soon as possible. The necessity for bed rest due to extreme discomfort.Fever and chills if an infection is present.Pain in the side of your abdomen or groin area.When they become lodged in the ureter, symptoms include: Staghorn stones can cause severe pain in your back or abdomen that lasts more than 10 minutes. READ THIS: Kidney Stone During Pregnancy Symptoms And Prevention What are the symptoms? People with staghorn renal calculi may need medication or surgery to treat it. However, Staghorn stones are large enough that they cannot pass easily through the urinary tract and instead lodge into a part of the kidney or bladder where they can cause discomfort.ĭoctors recommend that people with this condition drink plenty of water each day to help reduce the build-up of minerals in the body and flush out existing stones. These crystals stick together to form stones that are usually small enough to pass through the urinary tract without causing any symptoms. In addition, Kidney stones can form when urine contains too much calcium or oxalate. ![]() If your body has too much calcium or oxalate, you may experience problems with your kidneys or urinary tract. The bladder stores urine until it is ready to be excreted from the body. These substances are transported to the bladder through ureters, which connect the kidneys to the bladder. The kidneys filter waste and excess fluid from the blood. Most people who have staghorn renal calculi also have other types of stones present in their urinary systems. Staghorn renal calculi occur when calcium or uric acid forms into a stone, which becomes lodged in the renal pelvis, or the funnel-shaped part of the urinary tract. Renal calculi are known as kidney stones. This type of kidney stone can affect the function of the kidneys. They are typically large and can be difficult to pass. If left untreated, staghorn calculi result in chronic infection and eventually may progress to xanthogranulomatous pyelonephritis 5.Staghorn renal calculi are kidney stones that form in the shape of a stag’s horn. Staghorn calculi need to be treated surgically, usually PCNL (percutaneous nephrolithotomy) +/- ESWL (extracorporeal shockwave lithotripsy) and the entire stone removed, including small fragments, as otherwise, these residual fragments act as a reservoir for infection and recurrent stone formation. When viewed on bone windows they have a laminated appearance, due to alternating bands of magnesium ammonium phosphate and calcium phosphate 5. Staghorn calculi are radiopaque and conform to the renal pelvis and calyces, which are often to some degree dilated. The collecting system is filled with a densely calcified mass, producing marked posterior acoustic shadowing. 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. Uric acid and cystine are the underlying components of a minority of these calculi 5. Struvite accounts for approximately 70% of the composition of these calculi and is usually mixed with calcium phosphate thus rendering them radiopaque on both plain films and CT. Urease hydrolyzes urea to ammonium with an increase in the urinary pH 3-5. Proteus, Klebsiella, Pseudomonas and Enterobacter). 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.g. The majority of staghorn calculi are symptomatic, presenting with fever, hematuria, flank pain and potentially septicemia and abscess formation. Staghorn calculi are the result of recurrent infection and are thus more commonly encountered in women 6, those with renal tract anomalies, reflux, spinal cord injuries, neurogenic bladder or ileal ureteral diversion. ![]()
