Hypertrophy of the intervesical ridge is one of the clinical manifestations of bladder neck contracture. Bladder neck contracture is an important bladder neck obstruction problem. The bladder neck is defined as a tubular section of the urethra extending 1 to 2 cm in length from the internal urethral orifice into the urethra. It includes the internal sphincter, but the internal sphincter is not the entirety of the bladder neck. Contracture of the bladder neck can be congenital or acquired. Congenital cases often have no clear cause other than typical local pathological changes and are more common in men; acquired cases are often due to local chronic inflammatory conditions such as posterior urethritis, prostatitis, and deltoiditis, and the incidence is not lower in women than in men. Congenital cases are mostly seen in children, often with urinary disorders before the age of six, but it is not uncommon for them to develop after the age of 20 or 30. Etiology of intervesical ridge hypertrophy: Intervesical ridge hypertrophy is mostly thought to be related to chronic inflammation, with pathological manifestations of submucosal smooth muscle in the neck replaced by fibrous connective tissue, with the bladder neck becoming pale, rigid and fixed, and the neck opening becoming narrow. The manifestation of bladder neck obstruction, i.e. prolonged difficulty in urination, appears. In women, also known as female prostate disease, it is more common in middle-aged and older women. Bladder neck contracture in men can occur at the same time as prostatic hyperplasia. Therefore, the bladder neck should also be shaped after prostate removal, otherwise the obstructive symptoms cannot be relieved.
