Bladder diverticula are outpouchings of the bladder. They can be congenital (present at birth) or acquired (develop over time). They are more common in men and can be of varying sizes. Many bladder diverticula do not require treatment. Some diverticula can be associated with urinary tract infection, bladder stone formation, voiding dysfunction or bladder cancer. In these instances they may require surgical removal. Bladder diverticulectomy can be performed through a robotic approach. See Other Robotic Procedures for more information.
