Bifurcation of the urinary stream is generally divided into occasional or transient bifurcation of urine and frequent or long-term bifurcation of urine. Occasional bifurcation of the urine stream is mostly related to urethral adhesions, urethral obstruction, or changes in the urine stream caused by excessive urgency. If the urine is bifurcated for a long period of time, it is necessary to consider the possibility of disease. Occasional bifurcation of urine is not a cause for concern, as it can be significantly improved by drinking more water, urinating more often, and paying attention to genital hygiene. If the urine is often bifurcated, you need to consider the possibility of circumcision, prepuce, urethral stricture, urethral stones, prostatitis, prostatic hyperplasia and other diseases, most of which are accompanied by frequent urination, urinary urgency, incomplete urination, painful urination, thin urine stream and other symptoms, need to combine medical history, physical examination and urinary routine, urethral ultrasound, urethrography and other tests to clarify the specific cause, and then make targeted treatment. As mentioned above, the main reason for the bifurcation of urine is to understand whether the bifurcation occurs occasionally or frequently, whether it is accompanied by symptoms of discomfort in urination and thinning of the urine stream to consider the specific cause of the bifurcation, and if necessary, the corresponding tests should be combined to clarify.
