Paraureteral Diverticulum of the Bladder

A paraureteral diverticulum is a congenital bladder diverticulum that develops dorsal or lateral of the ureteral ostium without evidence of subvesical obstruction (Hutch, 1961). With the increasing size of the diverticulum, the ureter may drain into the paraureteral diverticulum, and vesicoureteral reflux is possible. A large paraureteral diverticulum can cause subvesical obstruction by compression of the urethra. If necessary, surgical treatment includes the excision of the diverticulum and ureterocystoneostomy.
