Pelvic floor exercises is a must at least twice a day, 3 times even better, you can do them standing, sitting or lying down.
Also you may have a slightly tilted womb, which means it is not until you stand up and the position of the womb changes that the left over urine flows out.
Get a referral from the doctor to see a specialist or in some area it is the incontinence nurse who deals with this.She teaches you all the perfect exercises. She will also measure by scanning your stomach whether you are emptying properly each time.
I am going to look into the Touch Sure I like the sound of that as it is hard to remember the exercises every day, but they really do help. Good luck
