7 Things A Nurse Wishes You Would Ask Before Starting A Bladder Tablet

The first thing a doctor sits down and explains, if there is time, is that a bladder tablet works on the signalling between the bladder and the brain. It turns down the message.

That is a sensible thing to do if the message is at fault — if a bladder is telling the brain it is full when it is not, and the nerve carrying that message is overexcitable.

In the older patients I worked with it very often was not. What I saw was bladders that genuinely could not hold what they used to, sending an accurate signal about that, and getting the accurate signal turned down. The nights got quieter for a fortnight and then came back, because the reason for the signal had not moved.

Almost every patient who came to my ward had been through both.

An ultrasound looks at a bladder as a container — how big it is, what shape it is, how much is left after you go. A urine culture is looking for infection. A pressure study looks at the muscle. Three good tests, and none of them looks at the surface of the wall itself.

So a patient with a real amount of deposit on that surface goes home with three normal results and is told, in good faith, that there is nothing wrong. Which is not the same sentence as nothing was found.

The one thing every patient tries before we ever meet, and the one I spent the most time undoing.

Concentrated urine irritates a lining that is already irritated. Drink less in the evening and what arrives in the bladder overnight is stronger, and a wall that was already calling early calls earlier. Then you wake up with a mouth like paper, drink a glass, and get up again for it anyway.

I am not telling anyone to drink a litre at bedtime. I am telling you the restriction is not buying what you think it is buying.

Every ward round I did, there was somebody telling me the tablet had given him a mouth so dry it woke him. Then he would drink a glass of water, and I could tell you what happened next.

Dry mouth, dry eyes and a bit of mental fog on the older tablets are not trivial and they are not to be worn as some sort of trade-off. They are worth taking back to the person who wrote the prescription. There are other molecules, there are other classes, and there is a conversation to be had about the dose.

That conversation is not mine and it is not this article's. It is yours, and it goes better if you have a diary in your hand.

I gave out the sheet myself, hundreds of times. I stand by the exercises — for the patients whose problem is leaking on a cough or a sneeze, they are the right first thing to try.

But most of the patients I saw about getting up at night did not have a closure problem. They had an urge problem. The bladder announcing itself far too early. Strengthening the outlet does not change when the announcement arrives.

So they did the exercises properly for six weeks, saw nothing change at night, and came back convinced they had failed at something. Every single one of them, and none of them had failed at anything.

This is the item the whole list is really about, and it is the one I was never in a position to say out loud on the ward.

A bladder measures fullness by stretch. That is the whole mechanism: the wall stretches as it fills, and at a certain stretch a signal goes up. Now consider that urine is not clean water — it carries mineral salts, calcium oxalate, uric acid, phosphate. Over fifty or sixty years some of that settles out and bonds to the lining as a thin pale film.

Tissue carrying that film does not stretch the way bare tissue does. A bladder that cannot stretch reaches the signalling threshold at roughly a third of its capacity. That is a genuinely full-feeling bladder holding very little, which is exactly what my patients described — the urgency was real, and then hardly anything came out, and they thought they were imagining it.

And no routine test looks at it. In thirty years I never saw one that did.

This is the one that made me angry, and not at the patient.

A woman of sixty-eight who mentions this is often told, gently, that it is just her age. She hears, without anyone meaning it that way, that there is nothing to be done. So she stops asking. I have watched patients stop asking for a decade.

Age is a risk factor. It is not a diagnosis. Something physical changed between fifty and sixty-eight. Age is the clock it happened on, not the thing that happened.
