Ditropan experiences and voiding

I have been voluntarily voiding for 5 years sInce one month post SCI. My Urologist is now recommending that I use Ditropan for high bladder pressure. He also said that this my stop my ability to void voluntarily and that I would then need to use intermittent catheterization. Have any of you gone through starting Ditropan. Did it change your ability to void?

Thanks for your time.
