If a boy has bifurcation of urine, the more common cause is overcircumcision or prepuce, which can cause bifurcation in the process of urination. If there are no obvious symptoms of discomfort, such as localized pain, frequent urination, or painful urination, no special treatment is needed. The foreskin and glans will gradually detach after the boy becomes an adult, so no special treatment is needed unless there are uncomfortable symptoms. There are also cases where the narrowing of the urethra caused by trauma or inflammation results in bifurcation of urination, which can lead to the severity of the bifurcation and the thickness of the urine line becoming thinner over time, and even an increase in the pressure of urination, so it is advisable to go to the urology department for an examination to clarify whether there is a narrowing of the external urethra, and if there is a narrowing of the urethra, regular urethral dilatation is also required. Other cases are caused by physiological factors, for example, some boys are prone to increased abdominal pressure in the front part of the urinary habit, and the urine line is in a straight line, if the pressure decreases at the end of the urinary stage, the phenomenon of bifurcation will occur, no special treatment is needed.
