whewellite

01/01/1991 - "Vevelite was more common in calculi removed by operation, while vedeline was the more common form in spontaneously eliminated calculi. "
01/01/2004 - "Whewellite crystals were found in 78% of calculi. "
12/01/2000 - "With respect to their calculi, whewellite was present in 84.4% of cases and wheddellite in 26.7%. "
08/01/1987 - "Whewellite was the major component of calculi in all cases but the stones exhibited a peculiar morphological arrangement, with multiple small indentations and a fine mamillary structure. "
01/01/1986 - "[Nucleus with calcified renal tubules in the interior of a small whewellite calculus]."

08/01/2000 - "In 27 calculi mainly composed of whewellite, the morphological analysis indicated primary hyperoxaluria; this diagnosis was confirmed in 25 cases by specific biological investigation. "
03/01/2019 - "Stone morphology helped us for detecting several pathological conditions: type Ic whewellite stones, as a marker for primary hyperoxaluria, was found in 17.6% of stones and type IIId ammonium urate stones, suggestive for infectious diarrhea, was identified in 20.1% of all stones. "

10/01/2019 - "The data showed that the majority of urinary calculi were calcium oxalate, either whewellite or weddellite. "
03/01/2018 - "Most urinary calculi have as a major component calcium oxalate which occurs mainly in two crystalline forms: Calcium oxalate monohydrate (whewellite) and calcium oxalate dihydrate (weddellite). "
08/01/2001 - "The selected constituents were whewellite, weddellite, and uric acid from which approximately 40% of the urinary calculi obtained from Macedonia patients are composed. "
06/01/1993 - "Apart from some practical limitations in data-handling facilities, we believe that PLS regression offers a promising tool for routine quantification, not only for whewellite, weddellite, and carbonate apatite, but also for other compositions of the urinary calculus."
03/01/1990 - "The majority of urinary calculi had mixed components: whewellite/apatite 28.98%, weddellite/apatite 24.31% and whewellite/weddellite/apatite 14.42%. "

11/01/2023 - "Kidney stones showed in particular, whewellite and kaoulinite crystallographic phases, that confers characteristics of greater crystallization with respect to the other stones. "
01/01/2012 - "The results of the observations of kidney stones in thin petrographic sections led to the identification of more cores in the same whewellite kidney stones. "
01/01/1985 - "Ultrastructure of whewellite kidney stones: electron-analytical investigation."
07/05/2018 - "Rietveld analysis of PXRD patterns showed that twelve (36%) of the renal calculi were composed exclusively of whewellite (calcium oxalate monohydrate, COM). "
01/01/1986 - "This notwithstanding, it is concluded that epitactic catalysis cannot and should not be considered a common mechanism for the formation of whewellite from weddellite (and vice versa) or of kidney stones in general."
