Struvite is a type of urine crystal that consists of phosphate, ammonium, magnesium, and calcium. Struvite typically forms as a result of a urinary tract infection UTI or when a person has difficulty emptying their bladder. According to a study on uric acid stones, the primary cause of these stones is highly acidic urine. The authors also note that less common causes can include:.
Treatment for uric acid stones typically includes dietary changes and an increase in daily liquid intake. According to the National Kidney Foundation , calcium oxalate stones are the most common type of kidney stone.
Having too much oxalate in the urine can cause these stones to form. Oxalate is a common chemical that is present in a range of foods. As a person digests foods, the kidneys remove oxalate through the urine. If a person is not well-hydrated, chemicals can stick together and create a stone that may eventually pass or become stuck in the kidney.
Some people are more at risk than others of developing calcium oxalate stones. Risk factors include:. Cystine stones are another type of stone that forms in the kidneys or urinary tract. According to the National Kidney Foundation , cystine stones are typically larger than other kidney stones and tend to recur.
Cystinuria causes cystine stones. When too much is present, a stone may form. If urine crystals form into stones, a person is at risk of developing complications. According to the National Kidney Foundation , some complications of larger, untreated stones include:.
