I am 30 years old. I had a spinal surgery in dec 2013 due to a tumor called ependymoma. It was removed but since then I m not able to urinate naturally. I have to use a catheter to bypass urine myself. There is an improvement since surgery. But it's only 50% recovery I would say. Will it be fine one day or I will not be fine for the rest of my life. Are there any surgeries or medicines to take care of this disease.
