@2will2 with the valve closed obviously urine builds up in the bladder. I feel the urge to go every three hours or so. I need the catheter because my bladder muscle is shot.
The valve is just not a big deal. Buy them from Amazon. I take one in every time the catheter is changed and the nurse just sticks it on the end of the catheter then it tucks up inside my underwear.. I change the valve every month, even though I only have the catheter changed every three months.
Let me know how you are doing. Trust me, you are far from alone.
