Can a Brain Surgery Cause Neurogenic Bladder?

I suppose the surgery could possibly be the cause, but your doctor would be the best person to advise you or diagnose if it's possibly caused by some other medical problem.

I have bladder problems caused by damage to my left frontal lobe by a hemorrhagic stroke five years ago. At first I was totally paralized on my right side and had serious problems with urination, so much so, that I had to be catherized in order to completely empty my bladder. When I relearned walking, several months later, I began to notice decreased sensation on my right side as well as being unable to tell when I needed to urinate. For example, if I sat for long periods, especially if I sat on the ground with my legs out-streteched, I didn't even think about needing to go but when I got up, I had great difficulty making it to the bathroom in time. At night, I would wake and not know what had caused me to awaken, but I suppose it was because my bladder was so full that it caused pressure on other organs in my abdomen. So it seems that my stroke damaged the nerves going to my bladder. I have learned to not sit so long at one time and go to the bathroom more frequently, but I often have to consciously try to relax my bladder in order to urinate. You might try doing that too, perhaps it will help..
