RESUMEN
Background: traditional methods for evaluation of women with urinary incontinence include urodynamic studies with measuring the pressure in the abdomen, the bladder, and the urethra and urine flow analysis. In addition, cysto-urethroscopy, cysto-urethrography are used for visualization of the bladder and the urethra
Aim of the Study: urinary continence depends on a closed and empty urethra with high urethral pressure. High urethral pressure [Pura] depends on two factors; one is structural which is defined as damage and lacerations in the collagen chassis of the internal urethral sphincter [IUS], the second factor is acquired functional factor is having and maintaining high sympathetic tone at the IUS from toilet training
Patients and Methods: 40 women who from SUI are examined clinically and investigated with sonar scanning 3DUS. 20 cases control by 3DUS. Patients with primary infertility those who had no vaginal deliveries, did not suffer cognitive behavioral therapy. This study is done at Bab El-Sharia Maternity University Hospital during the period from January 2017 to June 2018
Result: the IUS, as it is a cylinder, the level and extent of the rupture along the cylinder will determine the type and the degree of urinary incontinence as well as the configurational shape seen on imaging [case with primary infertility two years ago]
Conclusion: we conclude that damage of the IUS leads low pura and stress urinary incontinence [SUI]. Childbirth trauma causes damage to the collagen layer [the frame] of the vagina that leads to redundancy of the vagina and vaginal prolapse
