Hydrocephalus: Anyone had a shunt?

I had a one week trial of InterStim several years ago. The procedure was done in my urologist's office but if I were to have it permanently installed I would have had to go to the hospital. I personally did not like the feeling of the stimulation. I also have problems with my spinal cord and I could foresee needing MRIs of my lower spine in which case I would have had to have the InterStim removed. My bladder issues have continued to worsen but not so much that I want something implanted. I have to self catheterize 4 to 5 times a day because I cannot completely empty my bladder. I have urge incontinence and cannot always get to the bathroom in time. I am 76 and retired and don't need to be out of my house for long periods of time and I manage with cathing at home and wearing pads 24/7. It's not ideal but I've gotten used to it. I do get tired of having to catherterize but I am managing for now. My bowel problems are mainly constipation and that is manageable most of the time with Benefiber and Miralax. I hope you find a solution that works for you.
