[Ultrasound morphologic parameters of female stress incontinence].
OBJECTIVE
The study compared ultrasound parameters of the lower urinary tract with patients' age, number of previous pregnancies as well as the grade of incontinence. Furthermore, the influence of postural changes was studied.


METHODS
Ultrasonographic examination of the vaginal introitus was performed on 222 patients using a 5 MHz scanner. The transducer was inserted along the body axis and a vertical plane was defined.


RESULTS
Urinary stress incontinence was found to be associated with the occurrence of cystoceles, the finding of a funnel-like opening of the proximal urethra, an increased retrovesical angle beta, and finally with a descent of the bladder neck. However, there was no significant correlation between urethral length and the grade of stress incontinence. In patients without urinary incontinence, the retrovesical angle as well as the position of the bladder neck were strongly related to parity but did not correlate with the patients' age. There was no significant difference between parameters when the patients were straining in a prone or half-prone position.


CONCLUSIONS
Sonomorphological pelvic floor disorder is based on previous pregnancies and correlates well with urinary stress incontinence.
