Cystinuria - Kidney Stones
The stones compared here in size to a quarter (a US $0.25 coin) came from the kidney of a young woman with cystinuria, the most common defect known in the transport of an amino acid (a building block of protein).
The stones were obtained by percutaneous nephrolithotripsy, a procedure for crushing and removing the dense stubborn stones characteristic of cystinuria.
