For determinination of the significance of asymptomatic bacteriuria (AB) among the conscripts in the North was performed a comparative study of 101 volunteers who had no complaints and urinary tract infection (UTI) and a history of 206 patients treated at the stationary UTI. Diagnostically important AB in soldiers was 3% and corresponded to inflammation of the urethra and prostate. Negative impact of subextreme conditions of service in the development of AB from the soldiers in the 12 months has not been established. AB in young men in 27% of such cases was accompanied by leukocyturia, in 36% with bacteriuria, determined by the overall analysis of urine, which is a comprehensive method of identifying the primary UTI.
