Urological aspects of Behçet's disease.

Behçet's disease, affecting mostly young males in the Mediterranean countries and Japan, is a multi-system disease with urological manifestations. In this prospective study of 100 consecutive patients with newly diagnosed Behçet's disease, we found that 89% of the males had experienced scrotal ulceration and 6% had epididymitis. We also observed sterile urethritis in 3%. Other urological abnormalities appeared to be coincidental findings.
