Pain in the urethra after urination in women is most often seen in infectious diseases of the urinary tract, but also in urinary stones, which require further examination to clarify.1. Inflammation of the posterior urethra or inflammation of the bladder neck can present with symptoms of increased pain after urination. It is accompanied by frequent urination, urgency and burning pain in the urethra. This is because inflammation of the posterior urethra or inflammation of the bladder neck can result in local mucosal redness and swelling and reactions such as exudation and erosion. After urination, the posterior urethra closes or the sphincter muscle closes, so there is localized painful mucosal contraction. The symptoms can be reduced or disappeared after anti-infection treatment. 2. If there are stones in the bladder or posterior urethra, pain after urination can also occur, accompanied by abnormal urination. If the stone is obstructed at the urethra, interruption of urination may also occur. After changing position, urination may return to normal. Ultrasound examination of the urinary system is required to confirm the diagnosis.
