Abstract

We have investigated the use of laser-induced fluorescence (LIF) as a diagnostic technique for identifying different types of kidney stone in vitro. The optimal treatment for a particular kidney stone depends on its composition. Stones are treated by several lithotripsy techniques such as electrohydraulic, shock wave, or laser lithotripsy. Some stones are particularly difficult to fragment and it is important to know the composition of a stone in order to choose the optimal modality. It would therefore be beneficial to have an optical technique for identifying stones in vivo. We are studying LIF as a possible diagnostic.
