Urinary stone analysis with Fourier Transform Infrared spectroscopy(520 cases).pdf

1、Urinary stone analysis is important technology in determining the possible etiology and the pathophysiology of stone formation.A better understanding of the stone composition may be helpful in preventing urinary stone fo
