However, EWSL SFRs are significantly decreased under the following circumstances: shock-wave-resistant stones (formed of calcium oxalate monohydrate, brushite, or cystine); the presence of a steep infundibular-pelvic angle; the presence of a long lower pole calyx (>10 mm); and the presence of a narrow infundibulum (<5 mm) (2).
SEM images and XRD analysis of the Ca-P deposit indicated the initial formation of brushite with its monoclinic crystal structure and characteristic peak at 11.
The most frequent individual crystalline component is calcium oxalate (70-80%), though up to 50% of these can also include calcium phosphate either in the apatite or brushite form.
They reported that supersaturation of urine with oxalate, uric acid, and brushite were the same for (G1) and (G3) and higher than (G2).
There are certain stone compositions, such as cystine, calcium oxalate monohydrate and brushite, that are more resistant to SWL and may be better served by ureteroscopic management.
11) In addition, high-density stones, such as those containing brushite, may be relatively resistant to fragmentation with extracorporeal shock wave lithotripsy and may require more invasive intervention.
Characterization of brushite as a re-crystallization product formed during bacterial solubilization of hydroxyapatite in batch cultures.
83,84) This electrochemical method is usually conducted in acidic calcium phosphate solutions and leads to the formation of brushite coatings which are subsequently converted into apatite by hydrothermal processing.
Armoured layers on medium- to coarse-grained sandstones were found to be sintered by gypsum with a contribution of brushite (Kobylka) or a thin coating of brushite (Rohliny--a site 200 m away from the described one).
29) Brushite (calcium monohydrogen phosphate) stones comprise about a quarter of calcium phosphate stones.
His bones below the waist were in excellent condition but much of the upper half of the body had been transformed into a white crystalline substance, mostly the mineral brushite.
