Urethral stenosis is the most frequently acquired disease of the male urethra. Currently there is a progressive increase of this condition's occurrence due to: improved living standard, increased number of permanent catheter bearers, surge of STDs incidence, and abuse of transurethral diagnostic or therapeutical instrumentation. However, and in spite of such increased incidence, the epidemiological features have been forgotten by most authors consulted who now focus more attention in the therapeutical aspects. This paper analyzes the most outstanding epidemiological aspects, in the province of Alicante, of 180 urethral stenosis corresponding to 175 males and 5 females, making some final considerations on the relevance of certain factors in the genesis of urethral stenosis: advanced age, depressed social class, active sexual life, STD history, urinary or genital infections.
