Funnel-like changes in the inner urethra

A bladder neck contracture X-ray examination showed a funnel-like change in the inner urethra. Bladder neck contractures are another important bladder neck obstruction problem. The so-called bladder neck refers to a section of tubular structure that extends from the inner urethral opening to the urethra by about 1 to 2 cm in length. It includes the internal sphincter, but not the entire sphincter. Bladder and neck contractures, as far as the pathogen is concerned, can be innate or acquired. Congenital subjects often have no clear cause other than the typical local pathological changes, and are more common in men. Acquired subjects are often caused by local chronic inflammation such as posterior urethritis, prostatitis, and triangitis. Females The incidence is not lower than that of men. Congenitals are more common in children, and symptoms of dysuria often occur before the age of six, but it is not uncommon to develop symptoms after the age of 20 or 30.
