Hospital, Trivandrum, under the scanning electron microscope showed the presence of …

Various stones were examined by a combined electron microscopy. Morphological
parameters of calcium oxalates and phosphates, struvite, urates, cystine, gypsum, siliceous …

Human urinary stone fragments and sections were decalcified in ethylenediaminetetraacetic
acid solution after embedding in 1% agar. These decalcified embedded stone specimens …

Analysis of 529 urinary calculi by SEM (EDXA) and following x-ray diffraction in nearly all
cases of oxalate-rich stones reveals a certain content of calcium phosphate, which in more …

In the past, a variety of techniques have been utilized to identify the constituents of urinary
calculi. Chemical, 1–2 optical, 1 X-ray powder diffraction, 1, 3 and infrared spectrometry, 3–4 …

The present project began some years ago as a study of urinary calculi from the standpoint
of crystal structure. The reader is referred to previous papers4• 5 for a description of the …

Texture and micro-morphology of 1615 urinary calculi has been studied using scanning
electron microscopy and X-ray micro analysis. Together with the results of X-ray …

Calcium oxalate calculi were studied first because of their relative simplicity and regularity
and their occurrence in normal kidneys and uninfected urine. The nuclei of calcium oxalate …

During a 5 year period, 500 stones from the upper urinary tract and 100 from the urinary
bladder of as many unselected and consecutive patients were obtained in one hospital and …
