The distance from the cervix to the urethra is about 8 cm. The uterus and the urethra are not part of the same anatomical system, as the urethra extends backward to the bladder and the opening at the front of the uterus is the vagina, which are separated from each other and are not unified organs. The distance between the urethra and the bladder is about 4-7 cm. The urethra in women is relatively short and straight, so it is more susceptible to inflammation and cystitis, and the uterus, vagina and urethra are relatively close together, which can also be contaminated by gynecological bacteria and lead to urinary tract infections. The female urethra is included in the labia majora and extends backwards. It is a muscular canal with a diameter of about 4-7mm and there is a female urethral sphincter at the bladder neck, which controls the opening and closing of the urethra for the purpose of controlling urination.
