I am 15 months post surgery and had bladder sensitivity/urgency for the first 6 months. Alcohol, tea, some spacey foods were all triggers, Also had a feeling of not empty afterwords so would would need to turn around and go back in. At 3 months went to see Urologist who did an ultrasound and said bladder was empty. She it would pass and recommended drinking a lot of water every day and less of the trigger drinks or foods for awhile. I did that and by 6 months was more normal. At this point I can drink Arnold Palmer's or alcohol, or spicy food with no urgency and the feeling of incomplete emptying has passed. I would suggest you give it more time and be sure you are drinking a lot of water.
