![]() A person generally recovers faster with fewer complications when a doctor removes the stone with PCNL.įollowing the procedure, a person should follow all recommendations from their doctor and medical team to help prevent complications and reduce the risk of recurrence. Recovery will vary according to the treatment. However, some studies show it has a high success rate compared with PCNL and other less invasive options.Īnother removal technique is extracorporeal shockwave lithotripsy, which uses shock waves or a laser to break up the stones. Open surgery involves making a much larger opening, leading to longer recovery times. ![]() Previously, doctors preferred open surgery to remove the stone and return kidney function. People may also need more than one surgery to remove the stones. The success of the surgery varies depending on the complexity of the stones, the surgeons, and other factors. ![]() They then insert a tube and use it to insert instruments that can remove the stone. During the procedure, a surgeon creates an opening from the skin to the back of the kidney. PCNL is a type of surgery to remove kidney stones. The gold standard treatment for staghorn kidney stones is percutaneous nephrolithotomy (PCNL), which doctors also use for other stones larger than 2 centimeters. Older evidence suggests that eating a reduced phosphate and calcium diet accompanying estrogen supplements and iron gel may help reduce the recurrence of staghorn stones.įor example, a person prone to uric acid stones can avoid animal proteins to help prevent their formation. Unlike other, more common types of stones, diet does not directly influence the formation of staghorn kidney stones. People in more developed countries often have access to earlier preventive care, which may lower the incident rate. surgery, such as gastric bypass surgeryĮvidence also suggests that they are more likely to occur in people living in developing countries.bowel conditions, such as Crohn’s disease or ulcerative colitis.The American Urological Association also list the following risk factors for kidney stones: ileal ureteral diversion, where, following a surgical procedure, a segment of the intestine directs urine through a stoma.neurogenic bladder, where the nerves or the brain cannot communicate effectively with the bladder muscles.They are also more common in people with one or more of the following conditions: They develop due to recurrent UTIs.įemales are twice as likely to get staghorn kidney stones than males. If left untreated, staghorn calculi result in chronic infection and eventually may progress to xanthogranulomatous pyelonephritis 5.There are several potential causes and risk factors of staghorn kidney stones. 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 hydrolyses 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, haematuria, flank pain and potentially septicaemia 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. ![]()
