Radially polarized, circularly symmetric optical vortex solitons are shown to be able to exist in Kerr media beyond paraxial approximation. Unlike those of the paraxial linearly polarized counterparts, the topological charges of these solitons should not be less than 2. The properties associated with these solitons, such as their spatial width, and longitudinal and transverse field profiles, are characterized to depend on their normalized asymptotic intensity u2infinity and nonparaxial degree. It is found that the asymptotic intensity u2infinity of these solitons cannot exceed a threshold value in correspondence of which their width reaches a minimum value.
