Brief Summary:
Continent women have an intact internal urethral sphincter that extends from the bladder neck down to the perineal membrane. The internal urethral sphincter is a strong collagen muscle tissue cylinder lined by urothelium. On ultrasound scanning tissue echo will be detected torn internal urethral sphincter will not stand sudden rise of abdominal pressure. Three dimensional ultrasound assessment of the internal urethral sphincter is very sensitive and specific for the diagnosis of stress urinary incontinence.

Condition or disease Intervention/treatment
Urinary Incontinence Due to Urethral Sphincter Incompetence Device: ultrasonography

Detailed Description:
The internal urethral sphincter used to be said it's a muscular ring but the investigators will visualize by three dimensional ultrasound it's a cylinder in shape and it's the cause of stress urinary incontinence by being torn by stretching the vagina during normal delivery.

Group/Cohort Intervention/treatment
stress urinary incontinence
group 1 women with stress urinary incontinence by ultrasonography
Device: ultrasonography
Other Names:
  • vilson E6
  • transvaginal probe

continent group
group 2 women without stress urinary incontinence by ultrasonography
Device: ultrasonography
Other Names:
  • vilson E6
  • transvaginal probe

Primary Outcome Measures :
  1. evaluation of the internal urethral sphincter and assesst the extend and degree of the torn internal urethral sphincter [ Time Frame: 6 month ]
    we are going to do 3d ultrasound by transvaginal probe to see the internal urethral sphincter if torn or not and evaluate the morphology of the urethra and pelvic floor structure
