Bladder volume and diagnosis of pathologies

The bladder acts as a kind of receptacle for the accumulation of urine with subsequent withdrawal through the urethra.

Features unpaired penis

The average maximum bladder volume of approximately 750 ml. But man feels the need to go to the toilet in the volume of 150-250 ml. Capacity primarily depends on the age, sex and General state of health. In women it is characterized by smaller dimensions. This is due to the fact that in the region of the pelvis they are the internal sex organs.

In women, the norm is the volume from 250 ml to 500 ml. For men, this value is insignificant, but higher and of the order of 650 ml. For the amount of content of the urine in the body primarily affected by the individual structure and the extensibility of the walls of the body. Depending on this, people are able to hold up to one liter of urine.

Feature on the excretory system in children

Organ of the urinary system in children is higher than, a Mature man. With the growth of the baby, he quietly descends into the pelvic area. At this age, the mucous membrane of the organ is well developed, but the development of elastic and muscle tissue is insufficient. The normal capacity of the bladder in a newborn baby is not more than 50 ml.

A number of physiological capacity of the body depends on age:

  • The urge to urinate the children feel at 40 ml.
  • Ages 2 to 5 years at 50 ml.
  • Children older than five years experience need to go to the toilet when accumulation of urine in a volume of 100 ml.
  • At the age of ten years, the child feels the urge to urinate starting from 100 and ending with 200 ml.

Various pathologies

People suffering from incontinence are often faced with the phenomenon of leakage of urine is to completely fill the bladder. This is due to the fact that the person decrease in the bubble volume. In this case, it is necessary for him to be examined by a doctor-urologist to explore the situation and to determine the effectiveness and acceptability of treatment. In some situations a reduced capacity of the body is constant and no treatment is able to restore the normal value. In other situations therapy can restore normal volume.

In children, the bladder capacity is small. This is because children’s bodies are being formed. However, this does not prevent him to stretch and to shrink, acquiring the required value. People in old age, there is a enlarged prostate which in turn leads to a reduction in the number of places is designed to expand the organ.

In women during pregnancy bladder capacity is reduced by several times due to the growth of the fetus. Women in position have frequent urination due to the fact that there is a notification of the body about the emptying of the bladder nerve signals to the occurrence of retention of urine the muscles.

The reason of violations to the capacity of the on the excretory system

Various pathologies can also lead to a change in capacity of the bladder.

The development of certain pathologies leads to a decrease of the bubble volume. As a result, the enlargement process is much more complicated. Very often such changes are caused by interstitial cystitis, which is characterized by chronic inflammatory processes of the organ of the urinary system. Interstitial cystitis threat scarring and reduced capacity of the bladder. Also people suffering from the dysfunction observed reduction in the number of retained urine. This is caused by the rapid increase of the pressure in the body, resulting in the opening of the sphincter of the bladder.

In case of suspicion of the presence of such a problem, the doctor prescribes the patient a series of tests that involve the determination of the amount content of urine by means of a contrast agent. Contrast is injected directly into the body through the catheter. In some cases, the positive effect therapy. Treatment allows to increase the amount of urine content. Otherwise, the patient needs to adhere to and observe the precautions in order to avoid incontinence. In severe situations or in an adult lacks the ability (he just can’t) apply yourself to urinate catheters intended to drain urine.

What caused the change in size of the organ?

The amount of content of urine throughout life changes in smaller and in a big way. Women are also affected by the following factors:

  • Surgery performed on the organs of small pelvis.
  • Pathological disorders in adjacent organs.
  • The use of certain medications.
  • Tumors in the bladder.
  • Neurological disease.
  • Interesting position of women.
  • Changes in the body of an elderly person.

There are some studies in which it was noted the sizing on the strength of the strong stressful experiences. Such phenomena have been found not only in women but also in men. To solve this problem is possible only through the normalization of the General emotional state.

The manifestation of changes in the volume of on

Violations that occur in it, of course, can’t stay unnoticed both for women and for men. As this negatively affects the quality of life. For patients characterised by the following manifestations:

  • Frequent trips to the toilet more than five times a day not only in the daytime, but at night.
  • Presence the strongest urge to urination.
  • The volume of urine is much less, but the impulses are of high frequency.

When an organ of the urinary system decreases in size, it is much faster fills with urine, causing an acute need to bring urine. In that case, if the body has increased, and the contained urine is not increased also have problems with urination and accompanied by frequent desire to empty.


In order to indicate the range of the bladder is resorted to mainly modern and reliable methods of investigation – ultrasound diagnostics. In this survey, the authority conditionally compared with the cylinder, and with the help of special equipment is the process of determining its volume. The obtained data enable to evaluate the state of the body, to determine the presence of pathologies of the urinary system.

Also with the help of ultrasound is determined by how much urine is left in the system. Scientists found that the capacity of the above on remains unchanged since the formation of the urogenital system. Changes can be caused by diseases, surgery and so on.

How to be and what to do if you change the size of the body?

First, the patient is prescribed ultrasound, excretory urography, or cystoscopy.

The results of the survey, the ability to assign the optimal treatment. Also, special attention has been paid to addressing factors that resulted in such violations.

By reducing the volume of the bladder using such conservative methods of treatment:

  • Is gidrogeneratsia.
  • Through the urethra into the wall of the body is usual intravenous neurotoxins.

Surgical treatment involves performing myomectomy, cystectomy.

Increased on the patient set a special tube (catheters) in order to normalize the urine. Also additional doctor prescribes medications, physiotherapy and remedial gymnastics. If the increase was triggered by tumors, the patient undergoes cystectomy.

Refusal of treatment can adversely affect the health of the patient. In the future, he develops chronic renal failure or pyelonephritis.
