[Differential diagnosis of chronic urogenic arthritis].

Aim: To investigate features of chronic urogenic arthritis (CUA) and its differences with psoriatic arthritis (PA) and ankylosing spondylarthritis (AS) with joint lesion.

Materials And Methods: CUA, AS, PA were diagnosed according to S. M. Sidelnikova et al., S. van der Linden and Agababova, respectively, in 94 patients. The disease ran for more than 3 years. Articular syndrome was examined in CUA, AS and PA.

Results: Articular syndrome in CUA remains for the most part monoarticular with affection of the joints of the low extremities. AS has clinical and x-ray signs of sacroileitis, affection of the spinal column and hip joints. PA runs with multiple arthritic lesions of the hand and foot joints.

Conclusions: Chronic infection persists in all the CUA and PA patients. Its exacerbation coincides with arthritis aggravations. Only in CUA there is a chronological connection between acute or aggravated chronic urogenital infection and initial symptoms of joint disease.
