How can prostate disease contribute to urinary tract infections in men?
Prostate disease contributes to urinary tract infections (UTIs) in men primarily by causing obstruction of the urinary flow. In men over the age of 50, conditions such as prostatic hyperplasia (enlargement of the prostate gland) can compress the urethra, leading to incomplete emptying of the bladder.12
When the bladder is not completely emptied, the remaining urine becomes stagnant. This stagnation creates an environment that facilitates the growth of bacteria, leading to infection. Furthermore, if an obstruction is present, it can cause the infection to ascend the urinary tract, potentially resulting in more serious complications such as infection within the renal pelvis and kidney tissue. In some cases, the obstruction may be severe enough that the infection cannot be successfully eradicated with antibiotics until the physical blockage is removed. Additionally, the prostate itself can become a site of infection, often caused by bacteria that inhabit the stool.12
