Barry , i have had a SPC for five years now, and i don't have to get up in the night. The trade off is hooking yourself upto a night bag at night , disconnecting and draining the night bag in the morning. I had around 30-40 bladder spasms a day until I got on the right medication, now i have a couple a day sometimes none. The SPC change every 8 weeks are not without problems, I went through a long period of uncomfortable to painful changes but eventually found a routine that means changes are now well tolerated.
Can they not do a cystoscopy and get the stone, I did pass one naturally, not great but such a relief when I did .
At 70 I do drop off to sleep quite easily but never had HT or fatigue. HT is my next logical step.
Hopefully you can find some resolutions to your problems.
Thanks Chris
