Urine bifurcation

Introduction Urine bifurcation is caused by temporary obstruction of the anterior urethra or urethral opening. For example, the urination bifurcation that comes up in the morning is because the urine accumulated in the bladder overnight, the pressure inside the bladder is large, and the impact force when the urine is discharged is also large, causing a temporary change in the shape of the urethral opening. Sometimes after ejaculation, because part of the semen still remains in the urethra, and the congestion of the corpus cavernosum has not completely disappeared, it will also lead to urinary patency, and urination and bifurcation.

Cause

The following factors can cause the appearance of a urinary bifurcation:

1. Mild adhesion of mucosa of the urethra: The urethra has a urethral gland, which can secrete a small amount of mucus every day to play a role in lubricating and protecting the urethra. Under normal circumstances, these mucus remain in the urethra and have a protective effect on the urethra mucosa. When sexual stimulation is encountered, urethral secretions may increase and a small amount will flow out from the urethra. When the penis is erected, the urethral orifice may also have a small amount of secretion due to the squeezing of the urethra by the corpus cavernosum. After the urethral secretion is dried in the external urethral orifice, the mucosa and skin on both sides of the urethral orifice are slightly adhered. The urinary passage is slightly unsatisfactory. At the initial stage of urination, there is a bifurcation. A large amount of urine will spread out after the adhesion and disappear.

2, urethral stones: small urethral stones in the external urethral orifice after obstruction, urinary bifurcation can occur when urinating, but this is often accompanied by dysuria and hematuria. Urethral calculi were a frequently-occurring disease in the 1950s and 1960s and are now rare.

3, mucosal tumor or polyps of the urethra, because the tumor caused by the local urine through the poor urine and bifurcation, this situation is rare.

4, urinary tract anatomy abnormalities can also occur in the phenomenon of urinary bifurcation.

It is a certain disease of the genitourinary system, such as urethritis and prostatitis. In addition to urinary bifurcation, such diseases are often accompanied by frequent urination, urgency, dysuria and other symptoms. The causes of the disease are usually bacteria, chlamydia, mycoplasma, trichomoniasis, mold and so on. Under the invasive action of pathogenic microorganisms, the affected tissues and organs are inflamed, the urethral mucosal exudate or prostate secretions are increased, and the secretion contains mucin components. When the urine bifurcation is secreted and flows to the outer urethra, the water is evaporated. Mucin closes the urethral opening.

Differential diagnosis

Differential diagnosis of urinary bifurcation:

1, urethral fistula: urinary fistula (urinary fistula) refers to the abnormal passage formed between the reproductive organs and the urinary system, showing leakage of urine. Common vaginal fistula, urethra vagina, ureterovaginal fistula (collectively called urinary fistula). The genital fistula is an extremely painful injury. According to the urine flow, it is divided into external hemorrhoids and internal hemorrhoids. The external hemorrhoid is that the urine is partially or completely excreted through the abnormal passage of the urethra during urination, such as the genital tract of the penis, the scrotum, and the perineum. Internal hemorrhoids are urine that partially or completely flow through another organ in the body and then excreted, such as urethra vagina and urethral rectal fistula. According to the site of urethra in the urethra, it is divided into anterior urethra and posterior urethra. From the cause and time of occurrence, it is divided into congenital urethral fistula and acquired urethral fistula.

2, poor urination: the main reason for poor urination is due to obstruction on the urinary tract, or the lack of contraction ability of the bladder.
