Dynamic imaging of pelvic floor with transperineal sonography.

Real-time transperineal sonography has enhanced the appreciation of morphology and dynamics of the pelvic floor. Standard images are obtained from longitudinal and axial planes by placing the transducer between the vagina and rectum. This fast, effective, noninvasive and inexpensive examination represents the preferred initial diagnostic imaging tool for women with pelvic floor dysfunctions, such as prolapse and incontinence.
