The difference between signs and symptoms BethShelly BethShelly 8 71 Jun 7, 2017 by guest ( guest (

Urinary frequency its a SIGN, not a symptom and there is no official definition.

Definition of the symptoms of increased daytime frequency can be found http://wiki.ics.org/Increased+Daytime+Frequency

The term is a sign of the "storage" phase of the lower urinary tract , and includes "all the urinary voidings" and/or "the time between the voidings" in a non determine period of time. The universal way of collecting that information it is not established as well. The ICS promotes "bladder diary day" http://www.ics.org/public/bladderdiaryday, which is an exciting initiative for understanding the way that normal people void, and we have great expectations that with this will contribute to a definition of what is a normal frequency, at least in an statistically manner.

Today we usually get this information from frequency volume charts, and in a way that we could not understand this term is has been associated with polaquiria.

We usually are tempted to define what is normal and what it is not, and this seems to be reasonable, but when a term has so many variables, such us bladder capacity, compliance, food intake (solid or not), urgency, age, comorbilities, concomitant medications, etc.; are we sure that can define what is normal urinary frequency?

We should assume that a person who has a urinary frequency of 20 in 24 hs, for example, has an increased urinary frequency and of course this is a cardinal sign of overactive bladder and another syndromes. And we also can say that another patient with a urinary frequency of 2 times per 24 hs has a decreased urinary frequency, but what happens when a patient had a urinary frequency of 4 per 24 hs or 6 per 24hs: can we say it is normal or not ?

Take another example: a patient that usually void 4 times per 24 hs, began to void 7 times per 24 hs and he is strongly affected by that changed, can we say that this sign moved to a pathological pattern?

Or do we have to talk about a normal, decreased or an increased urinary frequency for that person in particular, in that precise period of his life, always referring to another lapse of time of the same patient ?
