What are the formation of kidney stones are similar to the firmation of supersaturated solution xrystals?

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 have provided a view of the histology of renal crystal deposition which suggests that the early sequence of events leading to stone formation differs greatly, depending on the type of stone and on the urine chemistry leading to supersaturation

Difference between normal and abnormal tissue is much clearer on mri than on ct and mri much suitable to view soft tissues
