About 4 and one half years ago I had a neck fusion that included all 7 vertabra. At the time of the operation I had to stay in the hospital for an extra week because the spinal channel film (?) was torn and was leaking fluid and they held me in until that cleared up. Anyway every since I had the fusion my urine stream has been weak and nearly unpredictable. And another thing is that the volume is just not there as before the fusion. I can not force it either, it is like there is no contact between my urge to urinate and the on switch.
