I'm 42 yrs old, 5'4, female, 215 lbs. i had lithotripsy oct 2010. i've gained 20 lbs since then, so i don't know if that could be a factor. For the past couple of years, I've had slight bladder leakage. After surgery, is has gotten to the point that I completely urinate myself, out of a chair, onto the floor and across the room. Stents were in place for two weeks before the lithotripsy, and one week following. Could they have caused nerve damage? Is theis the reason for my incontinence?
