Possible causes of urethral ectropion: 1. If there is urethral edema or inflammation of the urethra, this can cause urethral ectropion, the appearance of the urethra can be seen red and swollen, and local pain symptoms can appear. The urethral orifice can be ectopia if local topical medication or cleaning treatment is needed to eliminate the edema. 2. If there is inflammation of the urethral orifice, stones or cysts or polyps at the urethral orifice, ectopia can occur. Physical examination can see a local bulging mass at the urethral orifice, or local changes such as redness, swelling and rupture, etc. Relevant urine examination is needed, and if it is an infection, anti-infection treatment is needed. If there are cysts or polyps around the urethra, etc., the cysts need to be removed or polyps need to be removed, and the urethral ectropion can be cured.
