title: Percutaneous renal biopsy specimens in stone formers.
abstract: A series of renal biopsy specimens taken at the time of percutaneous nephrolithotomy were investigated for the presence and location of foci of microcalcification. Calcium was found in 18 of 25 (72%) of biopsy specimens from stone formers and in only seven of 30 (23%) of control biopsy specimens. This may indicate defective intrarenal handling of calcium as plasma calcium concentration was normal and 40% had a raised 24 hour urinary calcium excretion.
