  1. When bacteria alter the pH value of urine, crystals may form. Urolithiasis. When crystals have been in the urine for prolonged periods of time, one can develop urolithiasis or bladder stones
  2. pH urine role in drug therapy: Neomycin, kanamycin, and streptomycin are effective in alkaline urine. Salicylate intoxication keeps the urine pH alkaline. Sulfa therapy forms crystals, and these can be prevented by keeping urine pH alkaline
  3. Calcium Sulfate Crystals Calcium sulfate crystals are long, thin, colorless needles or prisms that are identical in appearance to calcium phosphate. The pH of the urine helps differentiate these two crystals, because calcium sulfate is found in acidic urine, whereas calcium phosphate is usually found in alkaline urine
  4. Crystals, which precipitate at a pH around 5.0, may have the shape of lozenges, hexagons (Figure 1) or ovoid structures, which mimic uric acid dihydrate, cystine or whewellite, respectively [ 2, 3 ]

Solubility of the crystals was twenty to thirty times greater when the pH was 7.5 than when it was 5.0. Hence crystalluria can be reduced to a minimum if the urine is kept neutral or alkaline and if an adequate daily urinary excretion is maintained. 2 Schwartz and his associates 3 demonstrated that sulfadiazine produces less crystalluria than. Foods, medications, metabolic products, and infection can cause abnormal urine colors .3 Cloudy urine often is a result of precipitated phosphate crystals in alkaline urine, but pyuria also can be. Salicylate intoxication keeps the urine pH alkaline. Sulfa therapy forms crystals and these can be prevented by keeping urine pH alkaline. pH urine role in diseases: keep urine pH acidic during : The treatment of urinary tract infection. In persistent bacteriuria. In renal calculi which develop in alkaline urine. Diet effect on urine pH. During treatment with sulfa drugs, alkaline urine helps prevent formation of sulfonamide crystals. Here are important points to remember about urinary pH: An accurate measurement of urinary pH can be done only on a freshly voided specimen Sulfa crystals can appear as needlelike sheaves (Figure 7). They can be clear or brown and are found in acidic urine. The crystals can be seen in patients taking sulfadiazine, indinavir, intravenous acyclovir, and triamterene. These drugs can cause renal damage when given in high volumes or to volume-depleted patients

The changes in the pH value of the urine may trigger the formation of crystals in the urine. The normal pH value of urine should be acidic, which is less than 7. When the value exceeded, it becomes alkaline, which then leads to the formation of calcium oxalate crystals in the urine. Urinary tract infection. The bacteria that causes urinary. Collection Instructions: Collect urine for 24 hours. 2. No preservative. 3. Specimen must be kept refrigerated during and after collection. 4. Specimen pH should be between 4.5 and 8 and will stay in this range if kept refrigerated. Specimens with pH >8 indicate bacterial contamination, and testing will be cancelled The stone formation may be without crystals in the urine or crystalluria may be without stone formation. Some of the crystals indicate some metabolic disorders like cystinuria or sulfa drug. Crystals are seen mostly in the concentrated urine. Crystals are divided into

Envelope shape crystals call as - calcium oxalate monohydrate and dumble shape crystals call as calcium oxalate dyhydrate. They are soluble in Hcl but not in acitic acid. Calcium oxalate crystals can also seen in urine with neutral PH. In diabetes mellitus & liver diseases the calcium oxalate crystals can be present in urine Daily monitoring of the urine for crystalluria allows prompt adjustment of sulfonamide dosing and more aggressive management of urinary pH and flow. In patients who have developed acute renal failure after sulfonamide administration, treatment involves fluid resuscitation to achieve euvolemia, after a vigorous diuresis in an attempt to clear. Sulfadiazine is a weak acid that will precipitate as crystals in the tubular lumen at a urine pH below 5.5; patients taking doses over 4 g/day should maintain a high oral fluid intake or receive adequate intravenous hydration Sulfanomide crystals are considered abnormal in urine. Appearance: flat needles, sheaves of small needles or as spheroids. Often brown in color. The presence of sulfanomide crystals..

Normal crystals may be present in acidic or alkaline urine specimens with no clinical meaning. These include the following: Acidic urine (pH ; 7):Amorphous urates: They are present in acidic urine. Refrigeration of the urine sample contributes to the. Salicylate intoxication keeps the urine pH alkaline. Sulfa therapy forms crystals, and these can be prevented by keeping urine. Crystal quick guide eClinpat . Urine pH will affect crystalluria because some crystals, such as struvite, form in alkaline urine, whereas other crystals, such as cystine, form in acidic urine

Sulfa Crystals; Indinavir Crystals; Uric acid Crystals. Uric acid Crystals: These crystals are of varying sizes and shapes, Mostly found found in acidic urine with PH below 7. Uric Acid crystals turn to resemble rhomboids, parallelograms, or rosettes in shape with an amber color. Though they are seen in normal urine, They also act as an. People can observe the hippuric acid crystals rarely. It looks like a plate or needle-like prism under the microscope. It can have a clear or yellow-brown color. The crystals often appear clustered together and not alone. The acidic urine PH can lead to the formation of the urine crystals Its potent urease splits ammonia, causing alkaline urine, which in turn precipitates crystals of struvite and apatite in the catheter lumen.6, 10 Methenamine preparations may be beneficial in. When there is an excessive buildup of one or more minerals, a urine crystal can form into a stone. Typically, urine crystals will cause limited signs and symptoms unless large enough stones develop

Amorphous urate crystals are urates salt of sodium, potassium, magnesium and calcium. Usual form is non crystalline and/or amorphous and appear as yellow-red granules. They are soluble in alkaline urine at 60ºC. They have no clinical significance. Sodium urates crystals : Sodium urates crystals may be present in urine as amorphous or as crystals

  1. Calcium carbonate crystals occur individually or in clusters and are variably sized, yellow-brown or colorless, radiant spheres or dumbbell shaped. They usually form in alkaline urine and are seen in clinically normal horses, goats, rabbits, and guinea pigs. Calcium carbonate crystals have rarely been observed in dogs
  2. Urinary crystals were identified using the combined knowledge of crystal morphology, birefringence features and urine pH (combined approach). When this was inconclusive, FTIRM was performed

  6. Use of triple sulfonamides (sulfonamide mixture) decreases concentration of each sulfonamide in urine and thus, Antacids tend to inhibit the GI absorption of sulfonamides, Hence, These are associated with the use of sulfonamide medication, sulfadiazine produces the so-called shocks of wheat crystals, Among these drugs, sulfapyridine and.
  7. As previously mentioned, urinary pH is an important factor in struvite formation. When a ferret eats a diet with mainly plant-based protein, the pH of the urine rises above the normal range. A pH above 6.4 can cause struvite crystals and stones to form

The presence of carbonate crystals (calcium) generally has little clinical significance. They are found in alkaline urine (pH greater than 6.5). The formation of calcium carbonate crystals can be caused by a combination of factors including decreased urine volume or a condition that alkalinizes (increases the pH of) urine, such as a vegetarian diet, chronic diarrhea, urinary tract infections. Drug Crystals • Many drugs excreted in the urine have the potential to form crystals. Hence, a review of the patients drug history is prudent when faced with unidentified urine crystals. • Most common among these are the sulfa drugs. Both panels on the right are from patients receiving trimethoprim-sulfadiazine. The differing appearanc pH. Urine pH is a vital piece of information and provides insight into tubular function. Normally, urine is slightly acidic because of metabolic activity. A urinary pH greater than 5.5 in the presence of systemic acidemia (serum pH less than 7.35) suggests renal dysfunction related to an inability to excrete hydrogen ions Sulfonamide crystals are typically yellow in color and often resemble uric acid crystals. However, sulfa crystals are easily distinguished from uric acid by confirmatory tests. Sulfa crystals are readily soluble in acetone and exhibit a positive dextrine/sulfuric acid test (old yellow newspaper test). Many drugs excreted in the urine have the.

  1. The normal urine pH ranges from 4.5 to 8 with an average value of 6. Change in urine pH promotes the formation of crystals because of changes in solubility and resulting precipitation. The risk of developing uric acid crystals increases with a reduction in pH value. People with acidic urine (pH< 5.4-5.8) are more prone to the formation of uric.
  2. urine pH decreases to ≤ 5.5 [11, 12]. Indeed, both sulfadiazine and, less commonly repor-ted, sulfamethoxazole can readily precipitate in the kidneys in certain clinical settings and cause an obstruction of the tubular lumen in the distal nephron from crystals admixed with cellular debris and proteinaceous material [6- 12]

1. Greatly increasing the urine flow. During the early years of sulfonamide use, patients taking the drugs were cautioned to force fluids. The idea was that if the glomerular filtration rate could be increased, there would be less opportunity for seed crystals to form in the renal tubules. 2. Increasing the pH of the urine In the process, the uric acid and other substances present in urine can start to harden up, thereby leading to crystal formation. Dehydration is also one of the reasons for urine crystals in the infants. Check: Dehydration Signs & Causes. 2. Changes in the pH of Urine. Urine is supposed to be acidic and has a pH below 7 Urine is one of the body's ways of excreting waste products. It contains many chemicals and some of them are in the form of solid particles, particularly crystals. Some crystals are normally present in the urine while others could indicate an abnormality. Presence of crystals in the urine is called crystalluria. (1, 2) Crystals in [

Crystals in dog urine usually form from minerals that are normally present in your dog's urine. The presence of the crystals is determined by factors such as pH, temperature, and urine concentration (also known as urine specific gravity). Some crystals form in acidic urine (pH < 7.0) while others form in alkaline urine (pH > 7.0) Crystals in the urine is known as crystalluria. Sometimes crystals are found in healthy people and other times they are indicators of organ dysfunction, the presence of urinary tract stones of a.

Crystals The formation of crystals is influenced by the pH and temperature of the urine. Although most crystals have no health significance, there are some rare crystals which appear because of certain amino acid metabolic disorders, and in patients taking sulfa drugs or other medications that are not very soluble Some crystals, such as uric acid, calcium phosphate and sulfa drug-related crystals have specific solubility characteristics which, with their shape and pH of the urine (and of course, clinical history), can aid in their identification. Sometimes, despite doing these solubility studies, the identity of the crystal remains a mystery Animals that have defects in the amino acid transport system excrete high concentrations of these substances in their urine. Cysteine, a nonessential amino acid containing sulfur, can precipitate into crystals and uroliths (stones) that can cause crystalluria, stranguria, dysuria, haematuria, urinary tract obstructions, and renal failure Crystals in the urine is known as crystalluria. Some types of crystals are associated with acute urate nephropathy and other types (like calcium oxalatin) are associated with ethylene glycol poisoning (antifreeze).

Sulfonamide Crystals urine of patients being treated for UTI due to inadequate patient hydration appearance in fresh urine can suggest the possibility of tubular damage if crystals are forming in the nephron 43. Ampicillin Crystals Following massive doses of this penicillin compound without adequate hydration 44 Kidney stone disease is a crystal concretion formed usually within the kidneys. It is an increasing urological disorder of human health, affecting about 12% of the world population. It has been associated with an increased risk of end-stage renal failure. The etiology of kidney stone is multifactorial. The most common type of kidney stone is calcium oxalate formed at Randall's plaque on. Uric acid crystalluria is caused when these oxalate crystals do not get diluted at the acidic pH of the urine. Calcium stones pass out from the body during this condition. Uric acid stones are mostly found in cases of glycogenosis, gout, neoplasms, and myeloproliferative syndromes PH measures antacid levels in urine and other fluids. Low antacid levels with a urine pH of 5 or less are typical of many uric acid stone formers. Normal urine pH is between 5 and 7. The optimal urinary pH in uric acid stone formers is usually around 6.5, so clinicians will typically ask patients to take enough supplemental urinary antacid. Bloody urine is common in urinary tract infections and kidney stones. These problems usually cause pain. Painless bleeding might signal a more-serious problem, such as cancer. Dark or orange urine. If your urine is dark or orange — particularly if you also have pale stools and yellow skin and eyes — your liver might be malfunctioning
