Congenital posterior urethral fistula

Urethral fistula (urethral fistula) refers to a pathological state in which part or all of the urine is excreted through the abnormal channels of the urethra or flows through other organs. According to the cause of the disease can be divided into two types of congenital and acquired. Congenital urethral fistula is rare, and is divided into anterior urethral fistula and posterior urethral fistula. Anterior urethral fistulas are extremely rare, and posterior urethral fistulas are more common than anterior urethral fistulas, often accompanied by rectal and anal canal deformities.
