Pelvic Floor Ultrasound is a comprehensive guide to the application of ultrasound in the diagnosis and management of pelvic floor disorders. It provides a detailed explanation of the physics behind ultrasound technology, the instrumentation used, and the optimal techniques for conducting pelvic floor examinations. A significant portion focuses on advanced imaging methods, particularly 3D and 4D ultrasound, which allow for enhanced visualisation and detailed analysis of pelvic structures. Maternal birth trauma to levator ani muscle and anal sphincter are a particular focus. As the use of implants becomes more common in pelvic reconstructive surgery, the book also addresses how ultrasound can be used to evaluate implant positioning and condition. A central theme is the integration of ultrasound into routine clinical practice, providing guidelines for interpreting ultrasound findings in a variety of pelvic floor disorders to facilitate obstetric audit, urogynaecological surgical interventions and conservative treatments with the aim of enhancing patient outcomes.
