What causes a staghorn kidney stone?
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.
What are the symptoms of staghorn kidney stones?
The majority of staghorn calculi are symptomatic, presenting with fever, hematuria, flank pain and potentially septicemia and abscess formation.
What is the most common cause of staghorn renal calculi?
Epidemiology. 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.
Do staghorn calculi cause pain?
Unlike other urinary stones that commonly produce symptoms (eg, renal colic) that necessitate intervention, treatment of struvite stones often occurs in patients without classic signs of nephrolithiasis; this is because large staghorn calculi may not cause acute renal or ureteral dilatation and resultant pain.
How do you get rid of staghorn kidney stones?
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.
How do they remove staghorn kidney stones?
In percutaneous nephrolithotomy or nephrolithotripsy, the surgeon makes a small incision in your back to remove kidney stones. He or she then puts a hollow tube into your kidney and a probe through the tube. In nephrolithotomy, the surgeon removes the stone through the tube.
What foods make kidney stones worse?
Avoid stone-forming foods: Beets, chocolate, spinach, rhubarb, tea, and most nuts are rich in oxalate, which can contribute to kidney stones. If you suffer from stones, your doctor may advise you to avoid these foods or to consume them in smaller amounts.
How is staghorn calculi diagnosed?
Plain abdominal radiography usually documents the extent of struvite staghorn calculi; however, additional imaging tests that reveal the anatomy of the renal collecting system can be helpful.
What size of kidney stones need surgery?
The larger a stone is, the less likely that it will pass without surgery. Surgical treatment is usually recommended for stones 0.5 centimeters in size and larger, as well as for patients who fail conservative management. The procedures used today to remove stones are minimally invasive and highly effective.
Can you live with a staghorn kidney stone?
Recommendations. A patient with a staghorn stone should be treated. If a staghorn stone is not treated, then renal deterioration occurs in at least 1 out of 4 patients. Over time, an untreated staghorn calculus is likely to destroy the kidney and/or cause life-threatening infections (sepsis).
How long is a ureteroscopy procedure?
Ureteroscopy is typically performed under general anesthesia, and the procedure usually lasts from one to three hours. If the stone is small, it may be snared with a basket device and removed whole from the ureter.
What symptoms would you expect if the stones lodge in a ureter?
Signs of Kidney and Ureteral Stones
- Pain in the back and side, often just below the ribs.
- Pain that changes, for example: It spreads to the lower abdomen and possibly the groin.
- Pain with urination.
- Nausea and/or vomiting.
- More frequent urination.
- Urine that is cloudy or has a strong, foul smell.
- Blood in the urine.
What are staghorn calculi normally composed of?
Staghorn calculi are most frequently composed of mixtures of magnesium ammonium phosphate (struvite) and/or calcium carbonate apatite.
What is the most common cause of a lower urinary tract infection?
The vast majority of urinary tract infections (UTIs) are caused by the bacterium Escherichia coli (E. coli), usually found in the digestive system. Chlamydia and mycoplasma bacteria can infect the urethra but not the bladder. UTIs are given different names depending on where they occur.
What are uric acid stones made of?
What are uric acid stones? A uric acid stone is a type of kidney stone, which is a hard object that is made from chemicals in the urine. After formation, the stone may stay in the kidney or travel down the urinary tract into the ureter.
