Calcium oxalate crystallization greater than 1.3 was not observed in any sample with a urimho value of 2 but it was noted in 31% of the samples with urimho values greater than 2. A positive relationship was also recorded between the urine pH and the urimho level, which is noteworthy ...

Our present study thus addressed effects of differential urine pH (4.0–8.0) on calcium oxalate (CaOx) crystallization, crystal-cell adhesion, crystal internalization into renal tubular cells, and binding of apical membrane proteins to the crystals. Microscopic examination revealed that CaOx monohydrate...
Patients presenting with vague flank pain, persistent urinary tract infection, and urine pH > 7 have characteristic coffin-lid struvite crystals in urine. In patients the removal of stone is not possible, and acetohydroxyamic acid, a urease inhibitor, has been recommended to prevent the growth ...
Urine crystals. Urine sediment was obtained by centrifugation (2,300 rpm/min for 5 minutes). Calcium oxalate crystals were photographed (Supplemental material) and counted in a Neubauer chamber following the formula: (final volume × number de crystals)/(initial volume ×...
Previous studies have shown that, whereas urinary pH is of limited importance for the ion activity product and solubility of calcium oxalate, crystals of calcium oxalate are rare in alkaline urine (Hallson and Rose 1978; Gregory et al. 1981; Gregory 1981). Furthermore, it was observed that ...
Change in urine pH –Urine is normally acidic. However, if it gets too acidic there is a possibility of calcium oxalate crystal formation. If it gets too alkaline, calcium phosphate crystals will most likely develop. Diet –High in protein and oxalate diet could lead to formation of crystals...
Human stones and experimentally produced calcium oxalate (CaOx) renal stones are composed of a crystalline and non-crystalline phase, the latter containing a variety of substances, some of which closely resemble cell membranes both structurally and chemically. Experimentally, CaOx crystals can be forme...
