Been having urinary retention, had cystoscopy, Dr said there was some polyps in the ureathra, but were too small to cause the prob, are polyps normal?

Bladder or medicatio. Urinary retention in women is not common. I see you are on an antidepressant which sometimes can effect bladder contractility to cause retention. Maybe stopping this med if you can might help. Most common cause of urinary retention in a woman is bladder muscle weakness (hypotonic bladder) for which not much can be done and if retention occurs the treatment is intermittent self catherization.
