Many people consider the bladder to be far from the most important organ and do not even think about its importance until they encounter any problems with the urinary system. However, if you delve into this issue in detail, it turns out that this body is not so simple. In this article, we will consider the structure and volume of the bladder in men from the point of view of the norm, talk about its functions and possible diseases.
The structure, volume, functions of the bladder in men
The bladder is called a hollow organ located in the pelvic area, in a filled state having a rounded or pear-shaped shape. From an anatomical point of view, three sections are distinguished in it, passing one into another:
The cervix (the narrowest part of the bladder), in turn, passes into the urethra, through which urine is excreted. The urethra in men has its own characteristics. It is much longer than that of women, and is sixteen to twenty centimeters long. Due to the fact that the female urethra is shorter and wider, they are much more likely to experience inflammation of the bladder — cystitis.
As we have already said, the bladder is located in the pelvic area. Its front part is adjacent to the pubic bone. Behind this organ in men is the prostate gland, and on the sides are the seminal ducts.
As for the structure of the bladder wall, it is represented by several layers:
- Serous (adventitial).
The most important is the muscle layer, which provides stretching of the organ when it is filled. The muscular coat is represented by smooth muscles, consisting of three intertwining layers: outer and inner longitudinal, middle circular.
Normally, the volume of the bladder in men is from three hundred and fifty to seven hundred and fifty milliliters. However, in order for a person to feel the urge to urinate, only about two hundred milliliters of urine should accumulate in the cavity of the organ.
A decrease in the volume of the bladder can be observed with a persistent spasm of the smooth muscle fibers of the organ wall against the background of a violation of their innervation or with the replacement of muscle fibers with connective tissue. An increase in volume is observed in various pathologies that lead to difficulty in the outflow of urine.
The main task of the bladder is the accumulation and removal of urine to the outside.
To date, a large number of various pathologies from the bladder are known. The most common among them is cystitis. However, men rarely experience cystitis. The majority of patients are women.
In addition, there is such a disease as an overactive bladder, characterized by rapid, sudden urge to urinate, including at night, involuntary excretion of urine. In 2015, scientists from St. Petersburg published a paper in which it was found that the incidence of overactive bladder among men in the world is 10-26%.
Urolithiasis, leukoplakia, polyps and tumors of the bladder — this is not a complete list of diseases of the bladder.
