Docs take it out without giving any anesthesia, I realized their is not even need for anesthesia, however may be they did filled my bladder with some anesthesia gel , and the used cystoscopy to do it. took just 5 minutes of mild pain (not even pain).
just after its taken out , was able to freely walk out of the operation theatre and was told to pee out the liquid they filled in, I had burning sensation while I went to pee but as far as I am told its normal, and I do feel its going away by itself the more I urinate.
Urologist gave me medicines since I have 4 more stones two in each kidney, they don't hurt as of now as they are small as 5mm and may be I pass it out while I pee, the most important thing is to drink enough water, after I had the stent removed I drank 2 liters of water then I got pressure.
To all those with Kidney stone problem drink enough liquid. surgery hurts even though its little . Lithrotripsy is not always a solution...
