What is the cause of urethrovaginal fistula?

I believe that many friends do not want to have any problems with their bodies, because you know, once there is some discomfort, you will need to spend a certain amount of time and money to see a doctor. You should know that urethrovaginal fistula is a disease that many friends worry about in their daily lives. So, what is the cause of urethrovaginal fistula? Let’s take a look at it below, and I hope everyone will understand it.

A urinary fistula is an abnormal passage between the reproductive organs and the urinary system, which results in urine leakage. Common ones include vesicovaginal fistula, urethral vaginal fistula, and ureterovaginal fistula (collectively known as urinary fistula). Genital fistula is an extremely painful and traumatic disease. According to the urine flow, it is divided into external fistula and internal fistula. External fistula is an abnormal channel in the urethra that allows urine to be discharged from the body partially or completely during urination, such as urethral fistula in the penis, scrotum, or perineum. Internal fistula is a condition in which part or all of the urine flows through another organ in the body and then out of the body during urination, such as urethra-vaginal fistula and urethra-rectal fistula. According to the location of urethral fistula in the urethra, it is divided into anterior urethral fistula and posterior urethral fistula. Depending on the cause and time of occurrence, it is divided into congenital urethral fistula and acquired urethral fistula.

Causes of urethrovaginal fistula are:

The causes of congenital urethral fistula are: ① After the 5th week of fetal development, the urogenital folds fail to separate the rectum from the urogenital diaphragm, causing the urethra to communicate with the rectum (male) or vagina (female), thus causing urethral rectal fistula (male) or urethral vaginal fistula (female). The former is often accompanied by congenital distal rectal atresia. ②Hypospadias. ③ Repeated urethra.

The causes of acquired urethral fistula are: ① urethral injury, such as urethral injury caused by combat injuries, traffic accidents, and industrial accidents, especially posterior urethral injury associated with pelvic fractures, and straddle injuries of the bulbar urethra. ② Injury to the urethra caused by surgery or instrumentation on the pelvis, anterior vaginal wall or urethra, or by stones or foreign bodies in the urethra. ③Defects of the urethra or anterior vaginal wall caused by childbirth or dystocia. ④ Malignant tumors of the urethra, anterior vaginal wall, and cervix, and radiotherapy.

The above opinions introduce the causes of urethrovaginal fistula in detail. I hope that after reading them, everyone will clearly understand what the causes of urethrovaginal fistula are. In this way, patients will be mentally prepared during normal treatment. In daily life, everyone must pay attention to curing the disease before focusing on work.
