Modern catheter bags are usually designed to prevent backflow, when I started my journey the bags were different, if you had a blockage I would lift the bag above the bladder and gently squeeze that usually unblocked the catheter. Today's bags don't allow that to work, they are now considered to be closed systems and are supposed to prevent infection.
With a SPC if mine gets blocked eventually I will leak out of my penis. With a urethral I would have "by passed" , that is when urine comes out between the catheter and the eye of the penis, it can be uncomfortable and if the balloon is right at the base of the bladder it can prevent urine passing past the catheter.
Going into retention and filling the bladder to the extent that it backs up into the kidneys is not good. I have been in retention a couple of times and it is uncomfortable. It is possible that if the catheter is blocked and the bladder fills at some point it will force the blockage out. If I feel my catheter is blocked I hold the urine and it usually unblocks the catheter.
Are you sure the pipes are kink free when he gets into bed at night ? I have 8 ml of water in my balloon but when it is changed they normally only get 2 ml out. From the experience of other long term catheter users that is normal. A deflated balloon may still be held in the urethra just by friction. Don't try to pull it out. Instilagel or hydrocaine is available without prescription at most chemist for £2-3 depending on the size.
Are you emptying the bag before it gets to full. No more than 2/3 full seems to be the normal advice.
There seems to be a contradiction on urethral healing, some say urine passing a wound is not good, on the other hand guys who have retzius prostate removal have SPC fitted not urethral catheters.
The nurse specialist on this site may be able to offer some advice.
