Never mind waiting to see the urologist - ask your GP to refer you to the incontinence clinic or incontinence nurse without delay. This has gone on long enough and you need a proper assessment. Ideally, you will have tests to see how much you can hold, the force of your flow, etc. You may just need something simple like bladder retraining. You will be checked to see whether you are doing your pelvic floor exercises correctly, and they will be able to refer you to a specialist physiotherapist if necessary. In many areas of the country, you will be entitled to pads on the NHS as you have been incontinent for more than 6 months.
Are you dry at night?
