[Incidence of urinary tract diseases among workers in the Masovian Refining and Petrochemical Plants in Płock 1978-1981].

The studies were aimed at estimation of the incidence rate of genito-urinary tract diseases among employees of the Mazovian Refining and Petrochemical Plants in Płock. In 1978-1981, 873 employees were examined, including 244 females and 629 males. Most of them, namely 572 (65%), were employed in those plants for more than 5 years. In 190 persons (21.8%) either history of urologic diseases (41 persons) or current diseases (149 persons) were found. The incidence rate of genito-urinary tract diseases was similar to that observed in general population. The studies are continued.
