I have 25% function in my left kidney and have passed many stones, the last stone blocked the Uretha and had to be blasted. Due to the condition of my kidney they say they can not blast the stone in the kidney, it is a staghorn 35mm. I have 75% function in the right kidney. I have renal scaring in both. Based on this what options other that kidney removal would you suggest I ask my specialist, he isn t a very easy dr to talk to but a good surgeon, so just looking for as much info as I can. Thank you
