What is wrong with a girl who has trouble urinating?

　　The most common disease that causes girls to have difficulty in urination is labia minora adhesions, which is manifested by the adhesion of both labia minora in the midline, covering the urethral opening and the vaginal opening. A small hole can be seen in front of the labia minora adhesions and below the clitoris, through which urine is eliminated, thus causing difficulty in urination and prolonged urination time.
