SUMMARY A survey of stone ultrastructure was made by transmission electron microscopy of thinsectioned material. Uric acid, oxalate, and phosphate stones have distinct, readily recognisable patterns. The feature common to all the stone material visualised is that the material is very finely divided and highly aggregated. Stereologic estimates of stone density made from electro‐micrographs differ sufficiently from macroscopically measured stone density to suggest that stone material visualised in the micrographs is not a random sample of a macroscopic stone.
