calcium phosphate urine

All were 100% hydroxyapatite. I do not manage them with just diet. Theyre found in acidic urine. I had less before the medication. Hypophosphatemia; [modified 2021 Oct; cited 2022 May 26]; [about 3 screens]. Because we cannot lower urine pH, the most crucial factor, we have to use what is left to achieve our goal. They may recommend cutting back on protein, for example, or reducing foods high in oxalate (as is the case for calcium oxalate crystals). high pH as >6.40 in the absence of urinary tract infection. These crystals are yellow-brown discs with concentric rings like a tree trunk. If ammonia production goes down, from kidney disease, for example, urine pH has to fall so acid can be lost on phosphate. Struvite stones, which always arise from infection with bacteria that possess urease, I have written a whole article on brushite, stone crystals parallel urine supersaturations, Because CaP SS depends powerfully on urine pH, In a recent article I trace out how calcium phosphate actually forms, how it is a rapid process, In the kidney cortex, far from where stones form, I wrote a whole article on how women raise their urine pH. In some cases, crystalluria is simply an artifact of handling. Provide warm sitz bath: for . Calcium oxalate crystals are heavily associated with kidney stones, which can form when too much oxalate (found in such foods as spinach) is in the system. From these we selected all who had a last stone CaP% at least 20% higher than that of the first stone (62 patients). Get helpful tips and guidance for everything from fighting inflammation to finding the best diets for weight lossfrom exercises to build a stronger core to advice on treating cataracts. Not shown here, but of interest, the number of shock wave treatments was higher among BRSFthan HASFsuggesting a link between shock wave treatment and brushite stones. Calcium oxalate crystals are shaped like dumbbells or envelopes. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Phosphate is made of the mineral phosphorous combined with oxygen. citrate is lower in normal men than women, In my primary article on dRTA, I present contemporary evidence that, if studied in detail, may not lower urine pH normally, Genetic hypercalciuria is very common among calcium stone formers, control urine calcium and bone calcium balanc, sugar as a factor that raises urine calcium, abruptly after the sugar load, lower urine calcium about 80 to 100 mg/d below the level predicted by sodium intake, They act in part to increase proximal tubule calcium reabsorption. Phosphate is an electrolyte. I eat a primal-type diet thats already low in sugar. Indinavir crystals may resemble starbursts, rectangular plates, or fans. Calcium phosphate: 5-10% when urine is alkaline (high pH) Dirty white Radio-opaque After shock wave treatments the treated kidney may excrete excess calcium and produce a urine of higher pH than it would otherwise do. These latter have more kidney damage than HA CaP stone formers, and are a special high risk group of patients. Hyperphosphatemia; [modified 2021 Oct; cited 2022 May 26]; [about 2 screens]. Low ammonia may be a way to separate them from the high ammonia of routine CaP stone formers. Your kidneys control the amount of phosphate in your blood by removing most of the extra phosphate through your urine. Can also be seen with hypercalciuria or hyperoxaluria (eg. Ultimately one can usually succeed in lowering CaP SS but it may take multiple tries. If urine crystals indicate high cholesterol, theyll order a blood test to evaluate your current cholesterol levels. studied eating the exact same diet in a research center. calcium and oxalate). Calcium phosphate crystals are normal in urine and their appearance look like a large flat-shaped plates orwedge-shaped prisms. This means that shock wave treatment affects tubule handling of multiple molecules, presumably because of injury. I am a 64yo female, BMI 22, no chronic medical issues or medications except that I have suddenly (in the last year) developed fast-growing kidney stones that are seemingly unrelated to any change in diet. Ammonia production is governed by body acid load, which we measure as GI anion and urine sulfate a residue of metabolic acid production. The general population contains more males than females at younger ages (blue dots). 24hr urine calcium >250mg/d in women and >300mg/d in men prior to indapamide use. Blood or pus in the urine; Restlessness, or pacing, looking for a place to urinate; Urinating in different places than usual; Malaise; Types. Depending on what your doctor finds, they may order additional tests. severe nausea, vomiting, or constipation; or. (2017). In fact, the very physiology of phosphate stone formation and the effects of shock waves on kidney function strongly support that idea as I shall show you. This is called crystalluria. Citrate also raises urine pH, because the alkali appears in urine as bicarbonate. Anyone who is prone to kidney stones should pay attention to good hydration. In addition, thiazide diuretics such as hydrochlorothiazide can help the kidney absorb more calcium, leaving less of it in the urine where it can form stones. This is because a high fraction of all calcium stone formers have genetic (idiopathic) hypercalciuria. Can be seen in healthy animals or in animals with calcium oxalate uroliths. What we try to do may not be done because patients cannot or will not do it, so we have to know when to try another approach. The main electrolytes include sodium, potassium, magnesium, calcium, chloride, and phosphate. Kidneys perform essential functions in your body, filtering waste and producing hormones. Sounds like cutting sodium and sugars from diet is a starter? The article you write on tells about it and links to others that expand on my little comment here. I have 3 sons (2 different Marriages) 2 were diagnosed with Pancreatitis when they were 5 years old. There are four major types of kidney stones: calcium oxalate/calcium phosphate, uric acid, struvite (magnesium ammonium phosphate), and cystine. If your phosphate/phosphorous levels are not normal, it doesn't always mean you have a medical condition that needs treatment. Calcium phosphate, also known as tricalcium phosphate, is a type of mineral. Theyre often a light brown color. Your doctor can help you determine what changes to make based on the type of crystals that you have. Symptoms of gout can include burning pain, stiffness, and swelling in a joint. When that happens, the calcium and oxalate form crystals. Some have proposed that CaP stone formers have high urine pH and low citrate as part of Incomplete renal tubular acidosis. Decisions about testing, and ultimately treatment, should be made jointly by the physician and the patient. No sense copying all that here, it is better to read the article. Litholink results (like many others here), High urine pH (6.84), low citrate (115), high calcium (259). A survey based on symptomatic rates of stone passage, by contrast, might give different results altogether. They help control the amount of fluid and the balance of acids and bases (pH balance) in your body. Calcium Phosphate Crystals These are colorless crystals having shape like blunt ended needles or prisms, rosettes. It results in high levels of cystine (an amino acid) in the urine, which then forms into kidney stones. Also, children often have higher phosphate levels because their bones are still growing. Struvite stones form when the urine becomes more alkaline. Factors incriminated in the etiopathogenesis of calcium phosphate urolithiasis include an alkaline urine pH, hypercalciuria, decreased urine concentrations of crystallization inhibitors, and increased urine concentrations of crystallization promoters. ethylene glycol or oxalate rich plant ingestion). For larger stones, providers may use minimally invasive or noninvasive treatments such as PCNL and shockwave lithotripsy. Regards, Fred Coe, Hello- The activity of many transport processes involved in calcium, Urinary pH and stone formation Rare in stones, vanishing in most urine, yet brushite supersaturation is foremost in importance for clinicians and patients.

If you have a problem with your kidneys or your parathyroid glands, the phosphate levels in your urine may be too high or too low. They may show up alone or in clusters. (2002). From the bladder urine, which mixes urine from both kidneys, one could never know this was happening. Hi Kelli, Brushite stones are critical to treat, usually with low dose thiazide + low diet sodium. This urine does, however, have a potential energy for precipitation, or the tendency to form crystals from dissolved salts. Over age 50, uric acid stones become a significant concern in both sexes. I have often argued to use diet as much as possible. Various types of crystals in alkaline urine: Alkaline urine crystals are: Calcium phosphate. Struvite is a type of urine crystal that consists of phosphate, ammonium, magnesium, and calcium. It seems better to say that CaP stone formers have abnormal proximal tubule functions, and make those the focus of new science. I am aware that calcium oxalate in stones matters, and that even high phosphate stones often contain that crystal. studiedmen and women we could document a uniquely low urine citrate of CaP stone formers vs. normal people. Thank you, Hi Steven, I presume you have acquired distal renal tubular acidosis from Sjogren Syndrome. Uroliths composed predominantly of calcium phosphates have been infrequently identified in dogs. They often appear in alkaline urine, though they can be found in normal urine. Calyx dilation (a abnormal finding) estimated during surgery was higher in HASF than in the other two groups, and papillary injury (papillae are the parts of kidneys inside calyces) higher in both phosphate groups than in ICSF. Contributor. Dietary oxalate is found in many vegetables, fruits, and nuts. calcium phosphate. The formation of various types of kidney stones is strongly influenced by urinary pH. Kidney stone symptoms include severe groin or abdominal pain, nausea, fever, and difficulty passing urine. CaOx stone formers had an average of 10 stones/patient attached to plaque, vs. only 3 plaque stones in 25 BRSF and 6 in 11 HASF stone patients: 10/ CaOx patient vs 0.12/brushite patient and 0.54/HA patient. Available from: Sharma S, Hashmi MF, Castro D. Hypophosphatemia. Acid load brought urine pH and almost all other measurements to equality between the shocked and control kidneys (loss of bolding). We used a massive database of kidney stone formers to ask what happened to urine pH in men and women with age. Regards, Jay, Hi Jay, Given three generations of stones one suspects a genetic cause and gene disorders are not being diagnosed with some important specific treatments as a result. Thanks! It can help in adjusting treatment. She is very healthy, active and slim. And the organs' functions are principally regulated via several hormones, including PTH, vitamin D, and FGF23. Leucine. Xanthine. elevated pH as 24-hr urine pH above 6.40. Can electrical brain stimulation boost attention, memory, and more? The most common cause of struvite stones is a bacterial infection that raises the urine pH to neutral or alkaline. Why NIH has yet to fund a calcium phosphate stone prevention trial escapes me. Available from: Merck Manual Consumer Version [Internet]. Its passed through the liver. I watch supersaturation for calcium oxalate as a secondary endpoint, and if it is high enough to promote risk above 3 I attempt to lower it by reducing diet oxalate. Calcium oxalate stone formation may be caused by high calcium and high oxalate excretion. No sense copying all that here, it is better to read the article. Risk for stone forming begins at a urine calcium of 200 mg/d in both sexes. high blood calcium--confusion, tiredness, loss of appetite, increased thirst or urination, weight loss; or. The laboratory test can identify the type of crystals by the shape of the crystals under a microscope. Please note the date of last review or update on all articles. Janus deity presides over beginnings and endings, gateways and doors, invariably dual in nature. When we adjust ammonia for acid load (lower right panel) CaP stone male and female stone formers remain high compared to same sex normals. 6. Other symptoms may include abdominal swelling, vomiting, nausea, disorientation, and malaise. No content on this site, regardless of date, should ever be used as a substitute for direct medical advice from your doctor or other qualified clinician. Most cystine stones can be managed by increasing hydration and medications that change the pH of the urine. Sign up to get tips for living a healthy lifestyle, with ways to fight inflammation and improve cognitive health, plus the latest advances in preventative medicine, diet and exercise, pain relief, blood pressure and cholesterol management, andmore. Being the first crystal to form, brushite supersaturation is crucial for stone prevention, a fact not intuitive but worthy of special emphasis. Return the container with your urine to your provider's office or the laboratory as instructed. This graph blurs the sex distinction because we used stone CaP% from both brushite and hydroxyapatite. Available from: Testing.com [Internet]. Most of your phosphate is stored in your bones. Amorphous phosphates. But a proper evaluation far surpasses any guess. Urine flow, and excretion of bicarbonate, potassium, chloride, sulfate, calcium, magnesium, sodium and oxalate all were higher from the treated side (bolded). For these reasons we turned to an animal model: The farm pig whose kidney is much like that of a human, and likewise is similar in size. I have yet to pass one so there is no stone analysis available, but bilateral stones nearly tripled in size in ~6 months. Indinavir is a medication used to treat HIV. However, PTH also decreases kidney reabsorption of phosphorus, so it is lost in the urine. However, this is rather a new approach and best done if you have a kidney stone center within reasonable distance. Because CaP SS depends powerfully on urine pHone expects and finds (upper middle panel) that urine pH tracks very closely with stone CaP percent. Philadelphia: Wolters Kluwer Health, Lippincott Williams & Wilkins; c2014. As expected, urine pH was higher in the BRSF and HASF than in the ICSF, as was supersaturation (SS) for CaP. CaP SS rose because we used potassium citrate as part of our treatment program. Any thoughts on Vitamin K2? During the collection period, store the urine container in a refrigerator or in a cooler with ice. Tissue damage is common, as is Nephrocalcinosis from plugging - often misdiagnosed as medullary sponge kidney. Phosphorus, calcium , and vitamin D work to make your bones strong and healthy. 2014 Jan 17 . All rights reserved. CaP(b) are CaP stone formers with only HA, no brushite in any stone. Calcium from bone may also play a role in kidney stone formation. It is an open question that seems obscure but whose answer might well lead to some new understanding of how stones form. We could find these abnormalities up to 90 days after shock wave. I am 58 Years old, and have producing Calcium Phosphate Stones for 30 years. They often appear in alkaline. For the urinalysis test, youll be asked to provide a urine sample. Cystinuria is a genetic condition. Theyre often found in acidic urine, and they may be caused by metabolic disorders like liver disease or tyrosinemia. [Updated 2021 Sep 28; cited 2022 May 26]. Twenty-four-hour urine chemistries and the risk of kidney stones among women and men. See additional information. Bethesda (MD): U.S. Department of Health and Human Services; Phosphorus: Fact Sheet for Professionals [updated 2021 Mar 26; cited 2022 May 26]; [about 25 screens]. Foods high in oxalates (nuts, spinach, potatoes, tea, and chocolate) can increase the amount of oxalate in the urine. Switching to a canned diet or adding water to food increases water intake and dilutes urine. Calcium Phosphate Stones. According to the American Urological Association, the presence of three or more red blood cells (RBCs) per high-powered field (HPF) in two of three urine samples is the generally accepted. Low diet (24 hour urine) sodium of about 1500 mg/d is the base to which I add chlorthalidone 12.5 mg daily with pre treatment and treatment 24 hour monitoring. This helps dilute the chemical concentrations in the urine, preventing crystals from forming. If it indeed lowers CaP supersaturation, I am prone to use it but with appropriate 24 hour urine followup and an inextinguishable skepticism. Hello Doctor, The number of plugs was 3 times higher in HA vs. Br patients: 12 vs. 3/mm3 of tissue volume. Hyperparathyroidism, a condition in which your parathyroid gland produces too much parathyroid hormone. Calcium phosphate crystals invade kidney tissue - so called tubule plugs. These can also be found in normal urine, particularly if it's acidic or refrigerated. CaOx stone formers predominate among the total of all cases. Seattle (WA): OneCare Media; c2022. They are found in urine with a pH above 6.5.

BRSF formed fewer but much bigger tubule plugs. May 2006 . Today, I would have left the brushite to one side, which would have made the female preponderance among those with high stone CaP% more marked because the sex ratio for brushite stone formers is closer to 1. High levels of bilirubin or bilirubin crystals in your urine could indicate liver disease or poor liver function. Calcium phosphate builds up in the urine, forming stones that can cause pain and, if they are large enough, block the flow of urine.
