I had a spinal fusion when I was 15 and it damaged nerves to my bladder which I still suffer from stress incontinence to this day. I am now 40. However, there is a surgery that can help. You need to see a urologist.
hi, I'm not sure but I think it can be. it depends on the location of the fusion too. which vertebra? if it is in lumbar region it can be because of that, but you should search other symptoms too. such as sensation disturbances, weakness of muscle or movement alterations... it is better to consult with his neurologist.
