Bladder diverticulaeare herniations of bladder mucosa through fibers of the detrusor muscle. We present the extravesical approach to a case of paraureteral bladder diverticulum in a six-year-old boy who had a history of recurrent urinary infection. In case of recurrent urinary complaints, the possibility of presence of a bladder diverticulum should be kept in mind. Voiding cystourethrogram is helpful for the differential diagnosis of the bladder diverticulum. Excision by extravesical approach of the paraureteral bladder diverticulum is a good choice.
