The enlarged prostate with stones may be caused by ageing, prostatitis, prostate hyperplasia and other reasons. 1. Age: With age, the size of the prostate gland will slowly increase, coupled with the metabolic function of the elderly degeneration, it is easy to form stones. 2. Prostatitis: Bacterial infection of prostatitis can lead to localized congestion and edema of the prostate, resulting in prostate enlargement; prostatitis can lead to urinary retention in severe cases, resulting in the formation of stones. 3. Prostatic hyperplasia: An imbalance in the balance of sex hormones in the body and the synergistic effect of estrogen and androgen lead to prostatic hyperplasia, resulting in the phenomenon of a large prostate. When certain calcium components in the prostate fluid are gradually deposited, stones will be formed. Enlarged prostate with stones can also be caused by other reasons. If there is any obvious discomfort, it is recommended to go to a specialized hospital immediately for examination and treatment under the guidance of a doctor.
