How many of u have msk on top of stones n how many interventions do u guys usually require? I average seven to nine general anastesias a year for stones plus have msk. I have nineteen stones in one side n thirteen in the other n lately ive been getting three stones obstructed at one time. My last two stents have come out of bladder n left me fully incontinent till the stent came out leaving me fully in a diaper.
