Microscopic examination was assumed as a reference method. Method using IVIS® constituted a diagnostic test. The comparison of the microscopic analysis and data from IVIS® imaging with manual setting ranges. This analysis did not distinguished number of spots within an urethra slice and only the presence/absence of transplanted cells in the particular slice registered by microscopy or IVIS®.
