Various

Regarding the rupturing of the urinary bladder, it is very difficult for this to happen because the bladder has a reflex which stimulates contraction when it is full, so any urine in the bladder will be propelled into the urethra and causing micturition. In patients having problems to urinate, it is routinely possible to drain about 1100 mls of urine through a catheter.So it is very difficult for the bladder to rupture. However, it is possible that the bladder ruptures especially as a result of bony fragments piercing the bladder wall following a trauma either to the pelvic girdle or to the lower abdomen (when the bladder is full). The rupturing can be of an intraperitoneal or extraperitoneal type both of which are usually accompanied by lower abdominal pain and hematuria (blood in urine). JMDebono 16:12, 21 February 2009

We'd rather want to know what urinary bladder is in man and in other mammals (vertebrates).

I think it is on males and other mammals. Vedantlath 16:11, 16 December 2005 (UTC)

The article states the bladder holds up to 530 ml of urine; I have measured my own micturation volume as up to 600 mLs. Ppe42 05:32, 22 February 2007 (UTC)

Nothing about bladder rupture, or trauma? Rosier 19:35, 22 February 2007 (UTC).

I was unable to micturition during surgery so my bladder was drained with a catheter, I had 900 mLs of urine. -Marko75 (talk) 21:14, 15 October 2010 (UTC)

Contradictory statements in article

The sentence,

"The desire to urinate usually starts when the bladder reaches around 125% of its working volume."

is very vague and contradicts the previous statement.

"If the amount of urine reaches 100% of the urinary bladder's capacity, the voluntary sphincter becomes involuntary and the urine will be ejected instantly."

Adult Human Urinary Bladder Volume

I have been doing some intensive googling in an attempt to get a better idea of what the measured volume of the human bladder actually is. There is quite a wide range of opinion. I now present my results in this notarised table:

Source	Bladder Volume Statement	Average Stated Bladder Volume
Hole, 1981	"as much as 600 mL of urine"	600 mL
Encyclopedia Americana, 2001	"... completely filled, the bladder can hold approximately 17 to 18 ounces (500 to 530 ml)"	515 mL
Magill's Medical Guide Volume III, 1998	"A completely full bladder is capable of holding approximately 1 liter of fluid"	1000 mL
Gray's Anatomy, 1901	"... the ordinary amount which it contains is about a pint." (470 ml)	470 mL
Britannica, 1985	"[the urge to urinate] can be voluntarily overridden until the content reaches 600 - 800 ml"	700 mL
Youngerman-Cole, 2006	"The maximum amount of liquid your bladder can hold is ... 400 mL (14 fl oz) to 500 mL (17 fl oz)"	450 mL
Dickinson, 2006	"The normal adult bladder should hold between 300 and 600 ml"	450 mL
Tong, 2005	"the average voided volume for the 20 [elderly male] participants was 532 ± 109 ml"	532 mL
Howison, 2001	"[urine volume] was measured and found to be between 500 and 600 mLs"	550 mL

I'd like to get other editors opinions on whether such a table about the range of estimates of bladder size is interesting/encyclopedic enough to go on the page itself.

The table could also be expanded with the various statements of the volume of urine which causes desire to micturate.

New page title

Isn't the name "Bladder (kidney)" extremely inappropriate as this organ is not part of the kidney? — The Storm Surfer 04:46, 15 May 2007 (UTC)

Trivia

• Here's a fun fact: A healthy bladder can hold up to two cups of urine for two to five hours.

• There is no trivia section. This is one of the most popular organs. I think it should have a trivia page.

Where is the female bladder located?

Has nobody noticed that female bladder seems to be separated from rectum and uterus (implying that the bladder is situated inbetween those two organs), while in reality uterus is the organ situated between the other two organs? This can even be derived from the names of the reccessi (rectouterine and vesicoterine). —Preceding unsigned comment added by 193.40.5.245 (talk) 17:41, 15 May 2008 (UTC)

I had trouble with this sentence: "In females, the bladder sits inferior to the uterus and anterior to the vagina...."

Could someone translate this? I am sure I'm not the only person who doesn't understand what "inferior" and "anterior" mean in this context.Risssa (talk) 23:36, 16 August 2012 (UTC)

Hi, and thanks for your contributions. I think your edits are being reverted for a couple reasons. First, notes to other wikipedia editors like "You are welcome to edit or dicuss this matter." should not be included in the article itself. Second, the statement "the bladder can take anything from 4¹/₂ to 12 hour" doesn't make sense. Does it take that amount of time to fill? (I would be skeptical of that claim as well, at least it makes sense.) mcs (talk) 16:57, 29 December 2010 (UTC)

The bladder can take (roughly speaking, this is right. Click here and go to school toilets for more info since about 16% of kids never urinate at school.) anything from 5¹/₂ to 8 hours to fill up.--85.12.88.17 (talk) 11:38, 4 January 2011 (UTC)

The bladder can take (roughly speaking, this is right. Click here and go to school toilets for more info since about 16% of kids never urinate at school.) anything from 5¹/₂ to 12 hours to fill up, depending on factors such as drinks. --85.12.88.17 (talk) 11:41, 4 January 2011 (UTC)

Ok. That might be true. But, the table still doesn't seem like it should be included in the article. Anna Frodesiak (talk) 11:56, 4 January 2011 (UTC)

I'm removing this again because the reference you provided does not support your claim. Where does the 10 hours number come from? If I drank a ton of water, I bet I could make my bladder fill in less than 5 hours. If you want to include some facts about filling time, find a source that directly states the facts that you would like to include. Until then, please stop adding the same claim into the article over and over again. Also, wikipedia does not generally include direct orders to the reader like "click here". mcs (talk) 01:05, 14 January 2011 (UTC)

I say about 5-10 hours is about right. This article now says that Mr average might Urinate every 5-10 hours but it's possible to go up to 24 or even 50 hours.

I recently underwent a brief spell of urinary retention (from March 24-26, 2012). Seeing as I am only 23 years old, this was alarming. I was unable to urinate at all for 48 hours before seeking emergency care. The doctors there were amazed when they did a bladder scan on me. They found almost 2000 mililiters of urine trapped in my bladder. That being said, they told me that the normal bladder only holds 300-350 mL of urine (equal to a 12 oz can of soda). My bladder held almost a full two liters. I've found numerous debates on this topic and decided to add what I was directly told by a medical professional from personal experience.

Capacity (again)

I see this has been discussed before, but again I raise the question of the human bladder capacity. The article says 300-350 ml, but there seems to be a big variation in quoted figures, and all those I have seen are greater than this, sometimes very considerably greater. See e.g. http://hypertextbook.com/facts/2001/DanielShaw.shtml . From personal experience also, 300-350 ml seems low. 86.179.4.189 (talk) 19:44, 16 August 2011 (UTC)

Measurement of volume

Quote from article:

It's almost impossible to give an exact measurement for the volume of the human bladder, ...

Why? Because different people's bladders are different sizes? Because there is some ambiguity about how the measurement should be made? 86.190.237.29 (talk) 02:01, 14 August 2014 (UTC)
