If there is an increase in the frequency of urination without painful urination, back pain, fever, etc., it may be caused by prostatic hyperplasia, as the gland protrudes into the bladder cavity after prostatic hyperplasia, stimulating the bladder triangle and causing the patient to urinate frequently; or there is too much residual urine in the bladder, so it takes several urinations to empty the bladder.
