What Does Increased Urination Urge After Kidney Stone Removal Indicate?

I just had surgery to have 2 kidney stones removed on Monday. I was prescribed Oxybutynin and tramadol and cyclobenzaprine and an antibiotic.....the urgency and frequency of me needs ding to pee has not gona away and I was wondering if I could take over the counter AZO or CYSTEX to help with the irritation of the stent?
