Paraureteral Diverticulum of the Bladder

A paraureteral diverticulum is a congenital bladder diverticulum, which develops dorsal or lateral of the ureteral ostium without evidence of subvesical obstruction (Hutch, 1961). With increasing bladder filling and increasing size of the diverticulum, the ureter drains into the paraureteral diverticulum. Vesicoureteral reflux is often associated. A large paraureteral diverticulum can cause subvesical obstruction by compression of the urethra. The surgical treatment, if necessary, includes the excision of the diverticulum and ureterocystoneostomy.
