Some elderly people who have a prostate ultrasound are told by the ultrasonographer that the prostate is normal in size. This result usually misleads the patient to the wrong conclusion that his prostate is normal and although he has symptoms of difficulty in urination he also subjectively denies having prostatic hyperplasia, thus rejecting the doctor’s opinion and treatment recommendations. The actual prostate gland is not necessarily large in size, but it will still affect urination. The symptoms of prostate enlargement are not positively correlated with the volume of the prostate, and the need for surgical treatment of prostate enlargement does not depend on the size of the prostate volume. If you have a long history of chronic prostatitis, a change in the prostate gland that has been treated with long-term oral medication to shrink the prostate gland, or an elderly patient with years of concurrent diabetes mellitus, you will have fibrosis of the bladder neck, making the bladder outlet stiff and unable to fully stretch during urination, making it difficult to wait for urination and urinate, unable to urinate cleanly at once; and then unable to fully contract and close after urination, with post-urinary dripping and a constant or frequent urge to urinate. Therefore, the small size of the prostate can also lead to some complications of prostate enlargement and surgery should be considered when treatment with alpha1-blockers is not effective.
