How thick is a man's urethra?

The male urethra starts at the urethral opening and ends at the head of the penis. If a man walks, there will be two bends. The growth and development and physical constitution of each man are different, so the thickness of the urethra is also different. However, few men in life know the specific value of the thickness of the male urethra. Knowing the normal value of the thickness of the urethra can timely treat urethral stenosis.

How thick is a man's urethra?

The diameter of the normal male urethra is 0.7-0.9cm, and the diameter of the normal female urethra is 0.8-1.0cm. The female urethra is slightly thicker than the male urethra. The normal male urethra has three narrow parts. The diameters of the three narrow parts and three dilated parts are as follows: the narrow parts include the internal urethra opening 11mm, the membranous part of the urethra 9mm, and the external urethra opening 7-9mm. The diameters of the dilated parts of the urethra include the prostatic part 15mm, the urethral ventral part 11-12mm, and the navicular fossa 10-11mm. According to the different narrow and dilated parts of the urethra, the cause of dysuria can be determined and corresponding treatment can be effectively made.

The male urethra starts at the internal urethra and ends at the head of the penis. This channel can be used for both urination and ejaculation. Therefore, it is both a part of the urinary system and a part of the reproductive system.

The total length of the urethra of an adult male is about 18 cm, which is relatively long compared to that of a female. The male urethra passes through three different organs and can be divided into three parts. The part that passes through the prostate is called the prostatic part, the part that passes through the urogenital diaphragm is called the membranous part, and the part that passes through the corpus cavernosum is called the corpus cavernosum. At the same time, because the male urethra is longer, it will have a certain degree of bend during the journey, and the thickness of the urethra is also different. Therefore, there are three narrow parts of the male urethra, which should be paid attention to.

The three strictures of the male urethra are clinically important areas to be especially careful of during operations. These three strictures are located at the internal and external openings of the male urethra, and where the urethra passes through the membrane. Because these three areas are relatively narrow, when men have urinary retention or need catheterization for surgery, they need to be careful to avoid damaging these areas, which may lead to certain complications.

The male urethra is longer, starting from the internal urethral opening, and there are two bends in the process of moving. Due to the different thickness of the urethra, there are three strictures. This anatomical structure is unique to the male urethra. Therefore, when performing urethral catheterization on men, special attention should be paid to these three strictures to avoid damaging the urethra, or even causing complications such as urine leakage.
