Is everyone's bladder the same size?
Both bladders are about the same size and can hold about the same amount of urine (2 cups according to Dr Oz). The main differences are the shape, due to where the bladder is located in a man versus in a woman, and the fact that the woman’s bladder seemed to have slightly thinner walls than the man’s bladder.

Are all bladders the same size?
Anatomically, it's highly unlikely anyone has a small bladder. Our internal organs don't tend to differ from one person to the next. However, it is possible to have a functionally small bladder, which means your bladder, for any number of reasons, can't hold a lot of urine.
What is the average size of a woman's bladder?
Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 ml (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.
How much does an average size bladder hold?
A healthy human bladder can hold between 400 to 500 milliliters of urine, or about 2 cups, before it reaches capacity. Though a healthy bladder can stretch and accommodate larger volumes of urine, it's important to urinate at regular intervals.
How much urine can the bladder hold?
Urinary bladder and urethra The urinary bladder can store up to 500 ml of urine in women and 700 ml in men. People already feel the need to urinate (pee) when their bladder has between 200 and 350 ml of urine in it.
What is considered a full bladder?
Once your bladder contains 16–24 ounces of fluid, it's considered full. Research tells us that the bladder has a direct line of communication with your brain. Your bladder is full of receptors that tell your brain how full your bladder is. Basically, there's an invisible “fill line” in your bladder.
Does bladder capacity reduce with age?
A urodynamic study of 436 men and women showed that, in both sexes, postvoid residual volume increased and peak flow rate decreased with age. Bladder capacity also diminished with aging.
Is urinating every 2 hours normal?
It's considered normal to have to urinate about six to eight times in a 24-hour period. If you're going more often than that, it could simply mean that you may be drinking too much fluid or consuming too much caffeine, which is a diuretic and flushes liquids out of the body.
How much urine can the bladder hold at night?
A healthy bladder can hold one and a half to two cups (300-400mls) of urine (wee) during the day and about four cups (800mls) at night. It is normal to pass urine five or six times a day if you drink between 6-8 glasses of fluid.
How often should you empty your bladder?
Try to urinate at least once every 3 to 4 hours. Holding urine in your bladder for too long can weaken your bladder muscles and make a bladder infection more likely. Be in a relaxed position while urinating. Relaxing the muscles around the bladder will make it easier to empty the bladder.
How long after you drink water does it reach your bladder?
Water absorption can occur as soon as 5 minutes after ingestion and peaks around 20 minutes after ingestion. Your kidneys are continually producing urine, so excess liquids are quickly eliminated via urine.

How big is a man's bladder?
The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out.
What is the normal capacity of the bladder?
The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out.
Where is the urinary bladder located?
All rights reserved. Prev. Next. The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine, allowing urination to be infrequent and controlled.
What is the sphincter that allows urine to flow out of the body?
During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out. Urine exits the bladder into the urethra, which carries urine out of the body. Because it passes through the penis, the urethra is longer in men (8 inches) than in women (1.5 inches).
Why does urine not exit the bladder?
Urinary retention: Urine does not exit the bladder normally due to a blockage or suppressed bladder muscle activity. The bladder may swell to hold more than a quart of urine. Cystocele: Weakened pelvic muscles (usually from childbirth) allow the bladder to press on the vagina. Problems with urination can result.
How to treat bladder cancer?
Bladder Treatments. Cystoscopy: A narrow tube is passed through the urethra into the bladder. A light, camera, and tools allow a doctor to diagnose and treat bladder problems. Surgery: Bladder cancer generally requires surgery. Some cases of urinary incontinence and cystocele may also be treated with surgery.
What causes pain in the bladder?
Cystitis: Inflammation or infection of the bladder causing acute or chronic pain, discomfort, or urinary frequency or hesitancy. Urinary stones: Stones (calculi) may form in the kidney and travel down to the bladder. If kidney stones block urine flow to or from the bladder, they can cause severe pain.
What is the first part of a urine test?
The first part of the test is a dipstick. If this is abnormal the urine should be looked at under a microscope. Cystoscopy: A narrow tube is passed through the urethra and into the bladder. A light, camera, and tools allow a doctor to diagnose and treat bladder problems.
How much urine does a human bladder hold?
Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 ml (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.
Where is the bladder located?
In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad fundus, a body, an apex, and a neck. The apex is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back ...
How does urine leave the body?
Urine leaves the bladder via the urethra, a single muscular tube ending in an opening called the urinary meatus, where it exits the body. Urination involves coordinated muscle changes involving a reflex based in the spine, with higher inputs from the brain. During urination, the detrusor muscle contracts, and the external urinary sphincter and muscles of the perineum relax, allowing urine to pass through the urethra and out of the body.
What are the causes of bladder problems?
Disorders of or related to the bladder include: 1 Bladder exstrophy 2 Bladder sphincter dyssynergia, a condition in which the sufferer cannot coordinate relaxation of the urethra sphincter with the contraction of the bladder muscles 3 Paruresis 4 Trigonitis 5 Urinary retention
How thick is the detrusor muscle?
It can also contract for a long time whilst voiding, and it stays relaxed whilst the bladder is filling. The wall of the urinary bladder is normally 3–5 mm thick. When well distended, the wall is normally less than 3 mm.
What is the organ that stores urine?
Pelvis. The urinary blad der, or simply bladder, is a hollow muscular organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In humans the bladder is a hollow distensible organ that sits on the pelvic floor.
What is the Latin word for bladder?
The modern Latin word for "bladder" – cystis – appears in associated terms such as cystitis (inflammation of the bladder).
How big is the bladder when empty?
4. In empty conditions, the Urinary Bladder resembles the shape of a pear. When the bladder is full, it takes an oval shape. As far as size is concerned, it is about 2 inches long. However, it can grow up 6 inches when full.
How long does the bladder hold urine?
For a person with healthy urinary system, the Urinary Bladder is capable of holding urine for a period of up to 5 hours. 27. When a person pees, the Urinary Bladder will completely empty itself. This happens each and every time a person urinates.
What is the trigone shape of the urine?
To be more specific, there are two flaps covering the Ureteric Orifices (openings of the Ureters) preventing backward flow of urine known as vesicoureteral reflux. This trigone shape is also responsible for preventing the Urethra from stretching as well. Urethra is from where the urine flows out.
How does a hollow bladder work?
The hollow design makes it work like a storage unit where urine is stored only to be disposed off at a later time. The urine it holds comes from the kidneys and enters the Urinary Bladder through two tubes known as as Ureters (singular: Ureter ). 3. The Urinary Bladder is very much like an elastic bag.
What happens when the bladder is empty?
When empty, the inner lining of the Urinary Bladder makes folds and tucks in. When urine fills in, the lining and hence the bladder expands to accommodate urine flowing in through the Ureters. 7. When empty the muscle walls of the bladder becomes thick and the whole organ becomes firm. However, this is only temporary.
Why does urine run down the bladder?
One thing of note here is that the urine runs down the Ureters because of: Gravity.
What is the name of the bladder that lies in the back of the body?
The Fundus is the other name for the base of the Urinary Bladder. It has a posterior location (that is, towards the back). It has a slightly triangular shape with the triangle tip pointing backwards. The Fundus in females lies against the vagina while in males, it lies against the rectum.
How many ounces of fluid is the average male bladder?
Follow Us: The average bladder capacity of an adult male is 13 to 20 fluid ounces. This is the quantity of liquid voided after severe urgency to urinate, according to Dr. Simon Kimm, Urologist.
Why does the bladder empty before reaching normal capacity?
The capacity can be decreased when ingesting foods or substances that increase the urgency to urinate, causing the bladder to be emptied before reaching normal capacity. The bladder can exceed its normal functional capacity when a person's urgency to urinate is suppressed, such as when the patient is under anesthesia.
Which doctor measures the largest dimension of a lesion on a CT scan?
Radiologist: measures the largest dimension of the lesion on the CT scan- depends on the plane of the scan and the extent to which the lesion is spherical, oblong or otherwise irregularly shaped.
Can bladder cancer be treated with a stratified risk?
No Yes. ×. Report. As you stated, the treatment for noninvasive bladder cancer depends upon the risk stratification. If it is low grade, single site, and less than 3 cm, it is stratified as low risk. If it is low grad but if tumors are found on multiple sites or greater than 3 cm, it is stratified as intermediate risk.
How to increase bladder outlet resistance?
To increase bladder outlet resistance, options include injection therapy into the bladder neck and urethra to increase tissue bulk under and around the bladder neck, a fascial sling, or an artificial sphincter.
What are the symptoms of bladder augmentation?
Indicators that augmentation is necessary include clinical symptoms, such as incontinence caused by bladder dysfunction unresponsive to medical therapy, and upper urinary tract deterioration due to inadequate low-pressure storage volume. Also suggestive is a measured bladder capacity that is significantly less than that expected for the patient's age. Caution must be exercised because with an incompetent bladder outlet, the bladder may drain at low pressure, making determination of functional bladder volume more difficult. Performing cystometrography with a Foley catheter balloon that occludes the bladder neck may provide more reliable data on functional bladder capacity. The generation of pressure exceeding 35 to 40 cm H2 O with urine volumes equal to those anticipated during 4 hours of urine production during the day or 8 hours of urine production during the night during maximal medical therapy further suggests that bladder augmentation should be considered.
What is ileal conduit?
An ileal conduit used as a urinary diversion strategy is recommended for conditions in which the bladder cannot be preserved. To increase bladder contractility, electrical stimulation with electrodes implanted on the bladder wall, pelvic nerves, sacral roots, and conus is used to elicit detrusor contraction.
Does a reconstructed bladder enlarge over time?
It is well known that the reconstructed bladder will gradually enlarge over time . At a constant pressure, a structure with a larger radius will accommodate a greater volume—again, an advantage of detubularized bowel segments. Several considerations must be entertained when choosing an augmentation donor site.
Overview
The urinary bladder, or simply bladder, is a hollow organ in humans and other vertebrates that stores urine from the kidneys before disposal by urination. In humans the bladder is a distensible organ that sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. The typical human bladder will hold between 300 and 500 ml (10.14 and 16.91 fl oz) before the urge to empty occurs, but can hold considerably more.
Structure
In humans, the bladder is a hollow muscular organ situated at the base of the pelvis. In gross anatomy, the bladder can be divided into a broad fundus, a body, an apex, and a neck. The apex is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back of the anterior abdominal wall to the umbilicus. The peritoneum is carried by it from the apex on to the abdominal wall to form the middle umbilica…
Function
Urine, excreted by the kidneys, collects in the bladder because of drainage from two ureters, before disposal by urination (micturition). Urine leaves the bladder via the urethra, a single muscular tube ending in an opening called the urinary meatus, where it exits the body. Urination involves coordinated muscle changes involving a reflex based in the spine, with higher inputs from the brain. During urination, the detrusor muscle contracts, and the external urinary sphincter and mu…
Clinical significance
Cystitis refers to infection or inflammation of the bladder. It commonly occurs as part of a urinary tract infection. In adults, it is more common in women than men, owing to a shorter urethra. It is common in males during childhood, and in older men where an enlarged prostate may cause urinary retention. Other risk factors include other causes of blockage or narrowing, such as prostate cancer or the presence of vesico-ureteric reflux; the presence of outside structures in th…
Other animals
All mammals have a urinary bladder. This structure begins as an embryonic cloaca. In the vast majority, this eventually becomes differentiated into a dorsal part connected to the intestine and a ventral part which becomes associated with the urinogenital passage and urinary bladder. The only mammals in which this does not take place are the platypus and the spiny anteater both of which retain the cloaca into adulthood.
