Frequent urination and incontinence.

I am 27 years male. Since childhood frequent urination problem . But recently from last 4 years sudden strong urge of Urination along with 4-6 drops of leakage and then I rushed to bathroom for urination . I consulted urologist and Urine culture, USG khub and PVR report normal . Doctor prescribed some medicine but these medicines has side-effect of hard stool which leads to anal fissure and another side effect is dry mouth . Doctors changed medicines 3 times but every time same side effect . Recently I had to go LIS surgery for fissure due to getting hard stool by taking above prescribed medicines. Another very detestable side effect of every medicine is intense dry mouth . So my question is only Adult Diaper is my only solution ??? Regular change of 2 diapers is very costly.
