Bowel Preparation Before 3D Rectal Water Contrast Transvaginal Ultrasonography for Rectosigmoid Endometriosis

"Rectal water contrast transvaginal ultrasonography is based on the distention of rectosigmoid with saline solution. Three-dimensional reconstructions convert standard 2D grayscale ultrasound acquisitions into a volumetric dataset.~Bowel preparation is based on a low-residue diet given in the two days before the examination and a rectal enema administered a few hours before the procedure."
