[The role of perineal ultrasound compared to lateral cysturethrogram in urogynecological evaluations].

PURPOSE
The aim of this study was to evaluate prospectively whether perineal ultrasound is comparable to the lateral cysturethrogram in the evaluation of incontinent women.


PATIENTS AND METHODS
Following urodynamic investigations, a lateral cysturethrogram and perineal ultrasound (5 MHz probe, bladder filling 300 mL) were performed in 98 incontinent women. In women with detrusor overactivity and consecutively reduced bladder capacity, ultrasound was performed at maximum capacity. To evaluate differences between perineal ultrasound and the cysturethrogram, the difference between bladder neck and lower border of symphysis and the retrovesicle angle beta were determined at rest and during the Valsalva manoeuvre.


RESULTS
Using perineal ultrasound, the differences between bladder neck and symphysis could be determined at rest and during the Valsalva manoeuvre in all patients. The determination of the retrovesical angle beta was possible in all patients at rest and in 89 of the 98 women during the Valsalva manoeuvre. The lateral cysturethrogram enabled the determination of difference between bladder neck and symphysis and the retrovesicle angle beta at rest in 81 of 98 women. During the Valsalva manoeuvre, the difference between bladder neck and symphysis and retrovesicle angle beta could be determined in 72 of the 98 women. In the 26 remaining women, the determination was impossible due to severe adiposity or cystoceles of the second or third degree.


CONCLUSIONS
Perineal ultrasound provides comparable data to the lateral cysturethrogram. In patients with adiposity, perineal ultrasound seems to be superior. Within the routine evaluation of women suffering from incontinence, the lateral cysturethrogram can be replaced by perineal ultrasound without any limitations of the diagnostic value.
