A variety of factors can contribute to the development of<unk><unk> s (i.e.<unk>  outlet obstruction causing chronic<unk>  distention and contact of the<unk>  wall with the<unk>  orifices, obesity, presence of space-occupying pelvic masses).
Most<unk><unk> s are asymptomatic and discovered incidentally during surgery or imaging studies performed for other purposes.
Patients with large<unk> s may have specific symptoms, such as reduction in size of the<unk>  mass after micturition and two-stage micturition (patient empties the normally located<unk> , then voids again after manual compression of the<unk>  sac).
