title: [The surgical and spontaneous elimination of kidney calculi--the type, incidence and treatment].
abstract: Results are reported of chemical (derivatographic and polarization microscopic) analysis of 2630 calculi removed by operation and 8607 spontaneously eliminated calculi. It was found that 82.7 per cent of the calculi removed by operation and 19.4 per cent of those eliminated spontaneously were mixed--composed of two or more components. The most common "pure" concrements were composed from oxalates and uric acid. The difference in the chemical types of the renal calculi of the two compared groups (removed by operation and spontaneously) is shown and followed up. Of interest is the different incidence of the two calcium oxalate hydrates in the two compared groups of renal calculi. Vevelite was more common in calculi removed by operation, while vedeline was the more common form in spontaneously eliminated calculi. Precision of the chemical form of the calculosis is recommended, with a view to including the genesis of stone formation for effective prophylaxis, treatment and metaphylaxis of the disease.
