Urine drops soiling one's clothes

Q: I am a mazoor suffering from incontinence of urine. By the blessing of Allah Ta'ala I have controlled my urine very much, but I still find a drop between two fardh Salaah times, which is enough for me to remain a mazoor. My question is if I find one drop between for example Asr and magrib, what are the rulings for me? Should I wash my private part for every Salaah, make wudhu and pray or should I only make wudhu and pray. With regards to clothing, I place a tissue in my undergarment when I go to urinate, but my question is for example before Asr time I go to urinate and keep the tissue paper and I don't remove it till after Esha Salaah and between this time I only make wudhu and perform Salaah, is there any problem in this?
