title: The sonographic appearance of fluid in the prevesical space.
abstract: A fluid collection within the retropubic space has a characteristic sonographic contour which, when combined with a partially distended bladder, resembles a yoke over a bell. The fluid conforms to the anterior convexity of the bladder. This configuration is distinct from that of ascites or a lymphadenectomy-related lymphocele.
