When it is empty of urine, the bladder is roughly the shape and size of a large grapefruit. When it needs to, though, it can expand to a much larger size, only to shrink back once it is empty again. It can hold nearly a half liter of liquid for two to five hours at a time without discomfort. It can hold more if it has to, but this is when we start to feel pressure and the need to urinate.
