Spectrophotometric crystallization curve: (1) start of increase of optical density (OD) reflecting crystal concentration in urine, (2) maximal OD (mOD) reached at the end of oxalate titration, (2)-(3) slow OD decrease (dOD/dtS) by sedimentation of single crystals, and (3) start of rapid OD decrease (dOD/dtR) indicating crystal aggregation.
