ABSTRACT
By combining these findings a new theory for describing the causes of female urinary incontinence was presented by Petros and Ulmsten, “the mid-urethra theory” (in early literature the integral theory) (13) . According to this theory damage to the pubo-urethral ligaments supporting the urethra, impaired support of the anterior vaginal wall to the mid-urethra and weakened function of the part of the pubo-coccygeal muscles, which inserts adjacent to the urethra are responsible for causing stress urinary incontinence. Connective tissue is an important element of the involved structures. The quality of the connective tissue has an influence on continence (14) .
