The common causes of urinary bifurcation include urethral stones, prostatitis, benign prostatic hyperplasia, urethral cysts, urethritis and so on. In addition, urinary bifurcation can occur after sex or during erection, which is caused by increased secretion of urethral glands and is a normal physiological phenomenon. The majority of them are caused by pathological factors, in addition to the above-mentioned congestion of the corpus cavernosum of the penis and increased secretion of the urethral glands. The most common in young men is urethritis, chronic prostatitis, etc. For treatment, use sensitive antibiotics according to the pathogenic bacteria and drink plenty of water to flush the urethra to relieve symptoms. Urethral stones are commonly caused by falling stones in the upper urinary tract, most of which can be relieved on their own after stone removal. BPH is common in the elderly and is caused by an increase in the size of the prostate gland, causing bladder outlet obstruction to form a urinary bifurcation, mostly accompanied by difficulty in urination, requiring oral medication for prostate enlargement or surgical treatment. The urethral cysts are less common and can also produce urinary bifurcation symptoms due to urethral obstruction. In addition, urethral strictures caused by trauma or medical injury can also cause bifurcation. In summary, the occasional bifurcation of urine is mostly a physiological factor, commonly after ejaculation or during the sexual impulse state. If you have frequent bifurcation of urine, you should be alert to the occurrence of disease and seek medical attention in a timely manner to clarify the diagnosis and treatment.
