Assessment of the Internal Urethral Sphincter and the Vagina by Three Dimensional Ultrasound

• Conditions: Urinary Incontinence Due to Urethral Sphincter Incompetence
• Interventions: Device: ultrasonography

• Registration Number: NCT02139956
• Lead Sponsor: Ain Shams University

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.

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.

Arm && Interventions

Group	Intervention	Description
stress urinary incontinence	ultrasonography	group 1 women with stress urinary incontinence by ultrasonography
continent group	ultrasonography	group 2 women without stress urinary incontinence by ultrasonography

Primary Outcome Measures

Name	Time	Method
evaluation of the internal urethral sphincter and assesst the extend and degree of the torn internal urethral sphincter	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
