Clinical Picture of Renal and Ureteric Calculus

  title={Clinical Picture of Renal and Ureteric Calculus},
  author={L. Pyrah},
Approximately two-thirds of all urinary calculi in man contain calcium oxalate as a major component. In the author’s department, in a series of 504 urinary calculi analysed by X-ray diffraction, 68.7% contained calcium oxalate [41]. In an analysis of renal calculi from 3000 patients, calcium oxalate was present in significant quantities in 64% [17, 18]. Similarly, the incidence of calcium oxalate calculi among all stone cases in man in Western Europe and North America has been stated to be 65… Expand
