A procedure based on scanning electron microscopic techniques is described for the
identification of crystals in urinary sediments and stones. The crystals are identified by their …

The methods of daily routine analysis of urinary stones in one laboratory, employing a
combination of microscopy, spectroscopy, chemistry, and X-ray diffractometry, are described …

Urolithiasis is a frequent and in many cases serious disease. Proper analysis of kidney
stone composition is crucial for appropriate treatment and prevention of disease recurrence …

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

Summary 10 urinary calculi have been qualitatively and quantitatively analysed using X-ray
diffraction, infra-red, scanning electron microscopy, X-ray fluorescence, atomic absorption …

A procedure for studying urinary stones by various microscopic techniques is described. The
stones are sectioned into approximately 0.2 to 1.0 mm. thick pieces using a low-speed saw …

A study of urinary stones obtained from patients after surgery in the Medical College
Hospital, Trivandrum, under the scanning electron microscope showed the presence of …

The definition and the frequencies of the components of urinary stones are presented on the
basis of more than 110,000 analyses. The stone morphologies are described. The methods …

Urinary calculi are often small (< 5 mg) and can be composed of many very different
constituents. The highly variable composition has lead to the development of many different …

THESE studies began as part of an investigation, in collaboration with Mr DA Andersen,
FRCS, which aimed at relating the composition of urinary calculi from various periods …
