If you are almost dry at night and nearly dry when sitting, there is still hope; it may be that you just need some help with bladder retraining. Generally speaking, if the night time continence is good then there is no mechanical damage.
It is a bit early for referral to incontinence services as this is still early days - the guidance is that you should regain continence between 3 - 12 months post op. If you are impatient, I think there are bladder training exercises you can download via google. Also check that you are doing the pelvic floor exercises correctly.
Note that bladder retraining and pelvic floor exercises are not the same thing.
