Urinary bifurcation is generally divided into physiological urinary bifurcation and pathological urinary bifurcation. The former is occasional or transient, mostly unrelated to disease; the latter is frequent or long-term urinary bifurcation, may be related to the prostate, should be timely diagnosis and treatment. The first one is occasional or transient and the second one is frequent or long term and may be related to the prostate. The former is more clearly diagnosed and treated because of its short duration and significant symptoms, while the latter generally has a longer duration and is more difficult to diagnose and treat. 50% of men will be affected by prostatitis at some point in their lives. Based on the symptoms, along with a prostate fluid examination can help in the diagnosis of prostatitis. Prostate enlargement mostly occurs in men over 50 years of age and presents with symptoms of urinary obstruction and irritation, i.e., waiting to urinate, thinning of the urine line, weakness of the urine stream, bifurcation of the urine, shortening of the projectile, dribbling and frequent urination, urgency, painful urination, nocturia, and urge incontinence. Transrectal prostate ultrasonography and urine flow rate examination can help in the diagnosis of prostatic hyperplasia. Early prostate cancer has similar symptoms to prostate enlargement, and if early intervention is not done in time, it can be tricky to manage when distant metastatic symptoms appear. For men over 45 years of age, regular rectal examinations and PSA tests can help in the diagnosis of early prostate cancer. For adult men, if the urinary bifurcation lasts for a long time, it is important to check the prostate gland for timely diagnosis and treatment, and of course, urinary tract diseases can also cause the phenomenon of urinary bifurcation.
