I have been using catheters 3 times a day, for my neurogenic bladder for almost 6 years, I would like to know if there is something new, a new drug, a surgery, a chip, or else to get rid of the catheters. I remember 6 years ago that using betanechol I was able to empty my bladder but I got afraid of hurting my kidneys. My glomerular filtration is around 55 to 60. Thanks Reinaldo Lopez
