    thoughts: when wearing diapers, when the bladder is full, the urine empties into the diapers so on rare occasions this doesnt seem to be the end of the world

    You don't have a spinal cord injury, so wondering why you are asking this , but no, it is NEVER safe with a SCI to go more than 4-6 hours between caths.

    People with SCI have a less compliant bladder, meaning that the pressure of the bladder can go up dramatically with filling, even with smaller amounts of urine, unlike someone who is AB.

    Few people with SCI wear diapers. Why are you using them??

    You cannot assume that a person who has overflow incontinence from an overfull bladder actually fully empties when they are incontinent. It is easy to be wet and still have 1000-2000 cc. of urine left in the bladder if your sphincter does not open properly or if you have a large prostate. Residual urine of any amount is a place for bacteria to grow and multiply, significantly increasing the risks for a UTI. An over-full bladder can start to bleed. High pressures in the bladder also decrease the blood flow to the wall the the bladder, making it easier for bacteria to attach and cause an infection.

    In addition, this incontinence would occur with very high pressures that could easily cause reflux of colonized urine to the kidneys, causing a possible kidney infection or even urosepsis. If the back-pressure on the kidneys is high enough, acute renal failure can occur. The more times this happens, the more the risks of kidney damage and possible eventual chronic renal failure (dialysis, etc. etc. etc.).

    If you are at risk for AD, serious, life threatening AD can occur at much lower bladder amounts than 1000cc.

    Alcohol is a diuretic and makes you produce more urine than the amount of fluid you take it, so it just makes this condition worse. If you are intoxicated, it is also much more easy to forget to do your caths. If you are drinking alcohol you need to cath more often, not less often.

    If someone with a SCI cannot or will not cath on a safe schedule, perhaps they should use an indwelling catheter. Although they have their disadvantages, intermittent cath done wrong can actually be more dangerous than an indwelling catheter.

    why is it that people with SCI have a less compliant bladder, meaning that the pressure of the bladder can go up dramatically with filling, even with smaller amounts of urine, unlike someone who is AB. Thanks.

    More than 80% of the nerves traveling from your brain down your spinal cord are inhibitory fibers, designed to tone down or inhibit reflex activity. This is true for the bladder as well, in fact the type of neurogenic bladder that people with TBI or CVA get is called an uninhibited bladder. It is these nerves that normally allow an AB person to have a fairly large bladder capacity with low pressures and without uninhibited bladder contractions (bladder spasm). If those pathways are disrupted, then the bladder can develop higher pressures.

    In addition, research shows that denervated bladders develop more collegen (connective tissue) between the muscle fibers of their bladder over time, and this actually makes the bladder "stiffer" and less able to stretch, which also increases the pressures.
