Abstract
Ultrasound imaging is rapidly replacing radiological methods in the investigation of pelvic floor disorders. Transrectal, transvaginal/introital and transperineal/translabial methods are being employed, with the latter probably the most widespread due to ease of use and availability of equipment. Position and mobility of the bladder neck, bladder wall thickness, pelvic floor muscle activity and uterovaginal prolapse can be quantified, and color Doppler may be used to document stress urinary incontinence. Ultrasound imaging has simplified audit activities and enhanced our understanding of the effects of incontinence and prolapse surgery, such as the new synthetic suburethral slings. In recent years, imaging methods have contributed significantly to our understanding of the traumatic effects of childbirth on the pelvic floor. Finally, the assessment of pelvic floor biomechanics may have implications for clinical obstetrics and ultimately for the prevention of delivery‐related pelvic floor trauma. Copyright © 2003 ISUOG.
