Abstract: Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms commonly affect older men. Men with BPH in Podgorica in almost half (47.5%) cases have positive urine culture, out of which 14.2% have polyinfection. Urinary tract infections are most common in the age group 71 to 80 years. Although both groups of men (with and without BPH) are more prone to gram-negative bacterial infections of the urinary tract, K. pneumoniae is significantly more common in men with BPH compared with men without BPH. The results indicate that treatment of men with BPH is much more complex than in men without BPH due to the fact that in the treatment, a number of strains are resistant to levofloxacin (resistance of gram-negative bacteria to levofloxacin at the level of 80.4%, with 89.7% of resistant strains of K. pneumoniae and 73.3% of E. coli strains, as well as resistance of gram-positive bacteria at level of 24.8%, with resistant strains of enterococci in 64.7% of the strains) and β-lactam antibiotics (53.4% of ​​isolated gram-negative bacteria synthesize ESBL enzymes out of which K. pneumoniae in up to 89.7% of the strains). Also, men with BPH have multi drug resistant strains in 53.1% of gram-positive bacteria and 79.7% of gram-negative bacteria. Carbapenems still represent a reserve group of drugs that have a good therapeutic effect in 93.2% of urinary tract infections in men with BPH.
