[Possibilities of 4D ultrasonography in imaging of the pelvic floor structures].
Technological boom of the last decades brought urogynaecologists and other specialists new possibilities in imaging of the pelvic floor structures which may substantially add to search for etiology of pelvic floor dysfunction. Magnetic resonance imaging (MRI) is an expensive, less accessible method and may pose certain dyscomphort to the patient. 3D/4D ultrasonography overcomes these disadvantages and brings new possibilities especially in dynamic, real time imaging and consequently enables focus on functional anatomy of complex of muscles and fascial structures of the pelvic floor. With 3D/4D ultrasound we can visualise urethra and surrounding structures, levator ani and urogenital hiatus, its changes during muscle contraction and Valsalva manévre. This method has great potential in diagnostics of pelvic organ prolapse, it may bring new knowledge of factors contributing to loss of integrity of pelvic floor structures resulting in prolapse and incontinence. Studies exist which describe changes in urogenital hiatus after vaginal delivery, further studies of large numbers of patients during longer period of time are though necessary so that conclusions can be drawn for clinical praxis.
