Understanding Urinary Incontinence in Men

Incontinence in men can be very stressful. It is important to understand how the urinary system works in order to better understand the causes of incontinence in men. Basically, it involves 4 primary body organs: The bladder, urethra, kidneys and the ureters.

The kidneys are responsible for filtering out toxins, excess fluids, and salt from the bloodstream. The waste products are converted to urine which flows from the kidneys to the urethra for bodily excretion. The kidneys initiate the process of cleansing the bloodstream. The kidneys also extract waste from the blood, like a filtration system. Thus it is vital to have at least one functional kidney in case you have problems with the other.

There's a ureter at the bottom of each kidney, which functions as a "drain". Each ureter moves urine from the kidneys to the bladder. Each ureter is a long, narrow tube, measuring approximately 25 cm in length. The ureter's muscular walls work to constantly push urine from the kidneys to the bladder. Once the bladder becomes at least 30% full, nerve endings signal the brain that it is time to empty it soon. Male bladders are double the size as a female's, holding approximately 800 mL. Thus, it takes twice as long for male bladders to reach the point where the signal is sent to the brian than for females. Two sphincter muscles work to release urine from the bladder. One is voluntary and one is involuntary. Humans can train the voluntary sphincter to tense and to relax at will. When the urethral sphincter muscles areWhen this muscle is relaxed, urine flows freely from the bladder to the urethra from whence it is excreted from the body.

It is situated between the pubic bone and the rectum, and is supported by the pelvic floor muscles. The urethra is the venue through which urine evacuates the bladder, the male urethra being approximately 18 cm in length, which is longer than that of a woman. Therefore, due to the larger size of the bladder and the longer length of the male urethra, men's sphincter muscles tend to be stronger than those of women.

Men have a prostate gland, which surrounds the urethra. Because it enlarges with age, it is one of the leading causes of incontinence in men. Other factors such as injury, illness, or genetics may also contribute to incontinence, but an enlarged prostate is one of the most common.
