Abstract

All stones share similar presenting symptoms, and urine supersaturation with respect to the mineral phase of the stone is essential for stone formation. However, recent studies using papillary biopsies of stone formers provide a view of the histology of renal crystal deposition which suggests that the early sequence of events leading to stone formation may differ depending on the type of stone and on the urine chemistry leading to supersaturation. Three general patterns of crystal deposition are seen: interstitial apatite plaque in idiopathic calcium oxalate stone formers, which is the site of stone attachment; tubule deposition of apatite, seen in all calcium phosphate stone formers; and mixtures of apatite and another crystal phase, such as cystine or calcium oxalate, seen in patients with cystinuria or enteric hyperoxaluria. The presence of apatite crystal in either the interstitial or tubule compartment (and sometimes both) of the renal medulla in stone formers is the rule, and has implications for the initial steps of stone formation and the potential for renal injury.
