Recently, according to a newspaper report, Chengdu City, Sichuan Province, there is a 68-year-old man surnamed Li, and several elderly people in the village to meet in the teahouse mahjong. As his “luck” that night was particularly good, so although urinary urgency also refused to go to the toilet to urinate, because he believed in the mahjong table on a saying “pee, lose a hang”, he was afraid that “pee a’x “After the “hand” will be moldy. Therefore, he held his urine from 7:00 pm that night until 2:00 am the next morning. Suddenly he felt a sharp pain in his stomach, the table poker friends rushed him to a hospital in Chengdu, the doctor found that he was holding urine too much and caused a bladder rupture, and caused peritonitis, doctors immediately did emergency surgery for it. Up to the time of the report, the old man surnamed Li was still not out of danger. From this example leads to a topic, why rubbing marijuana will lead to bladder rupture? The bladder is a muscular organ located in the lower abdomen. The main function of the bladder is to store urine, and generally the adult bladder can store 350 – 450 ml (milliliters) of urine. The normal adult male urine volume for 1 day is about 1500ml, while the female volume is about 1200ml. The kidneys produce about 50-80ml of urine per hour, which means that the bladder can store the urine produced in about 4 – 5 hours. Of course, this depends on each person’s specific situation, such as drinking more water to produce more urine, and sweating more to reduce the urine accordingly, etc. When the urine in the bladder reaches a certain amount, about 350 ml, it will stimulate the pressure receptors located in the bladder wall and produce the urge to urinate. At this point, normal urination action occurs through a series of nerve reflex activities that eventually cause contraction of the bladder smooth muscle. If urine from the kidneys is increasing and the bladder is unable to discharge urine in a timely manner for various reasons, the pressure in the bladder will continue to rise, causing various complications and even life-threatening bladder rupture as mentioned earlier. The fact that older men have varying degrees of prostate enlargement leads to an increase in residual urine in the bladder. The most important manifestation of prostate enlargement would be the increased frequency of nighttime urination and frequent urination. If older people often hold their urine, it will also speed up the rate of prostate enlargement. The actual fact is that you will be able to get a lot more than just a couple of days to get a lot more than just a couple of days. On the other hand, with age, the nerve response of the elderly is gradually dulled and the sensation of increased pressure in the bladder is sluggish. At the same time, the muscles of the elderly become less elastic and the smooth muscle fibers of the bladder tend to break, making it easier for a filled bladder to rupture when combined with an external blow. The old man surnamed Li, as mentioned earlier, because he did not want to “pee” and mold the “luck” of playing mahjong, for a long time to forcefully hold urine so that the urine in the bladder continues to increase, the pressure in the bladder also continues to rise, and finally more than the degree of bladder smooth muscle can tolerate This leads to bladder rupture. As the urinary extravasation caused by the bladder rupture can cause peritonitis, so the old man surnamed Li developed severe abdominal pain and even shock and life-threatening. Urine is a metabolic product of the body, and if it is stored in the bladder for a long time, it can lead to a variety of diseases. Such as cystitis, ureteral reflux caused by persistent or recurrent urinary tract infections, bladder stones, bladder diverticula, tension incontinence, hernias and so on. The so-called cystitis is an inflammation of the bladder caused by a large amount of urine stored in the bladder, where bacteria take the opportunity to grow and multiply and attack the bladder wall along with harmful metabolites in the urine. Normally, after urine is produced in the kidneys, it flows down the ureter into the bladder. The term ureteral reflux means that urine flows back up the ureter due to the increased pressure in the bladder. Ureteral reflux has been implicated as an important abnormality causing persistent or recurrent urinary tract infections. Both cystitis and urinary tract infections can present with symptoms such as frequency, urgency, painful urination, fever and back pain. Bladder stones, on the other hand, are formed by the precipitation of metabolites in the urine due to prolonged storage in the bladder, and can clinically present with symptoms such as hematuria, lower abdominal pain, and sudden interruption of urine flow. Hernia, also known as “small intestine gas”, is a disease in which the pressure in the abdominal cavity is raised for various reasons, causing the organs in the abdominal cavity to protrude into the void. The most common clinical cases are inguinal hernia and inguinal hernia. The author once treated a 64-year-old male patient who was a typical example of a hernia induced by holding urine for a long time. The patient had no major health problems until he retired. After retiring at the age of 60, he went to work as a janitor in a unit. After 2 years of work, he began to notice enlargement of the right scrotum, which gradually worsened. The enlargement of the scrotum was especially obvious in the standing position and after exertion, while it could shrink after lying down and resting. The disease seriously affected his work and daily life, so he came to our hospital and was examined and found to have an inguinal hernia, which is caused by the protrusion of the small intestine downward and into the scrotum through the inguinal canal due to increased pressure in the abdominal cavity. What caused the elevated intra-abdominal pressure? We took a detailed history and learned that since the gate duty room was far from the toilet and the nature of the janitor’s job did not allow him to leave his post for long periods of time, he gradually developed the habit of holding his urine. In addition, he drank a lot of tea every day in order to refresh himself, and tea has a diuretic effect. In this way, the increase in the production of urine, and not timely excreted out of the body, it leads to the pressure in the bladder constantly rising, and the pressure in the abdominal cavity also constantly rising. In the long run, this eventually leads to the development of inguinal hernia. Why do we often see “urinary leakage” in older men? Tension incontinence is one of the reasons. Tension incontinence is a phenomenon in which the bladder leaks due to increased abdominal pressure such as coughing or sneezing. For example, the prostate in older men is like the outlet of a water bag, and an enlarged prostate is the same as closing the outlet. When the water bag is too full and the outlet is not opened in time to release water, if we squeeze the bag, the water will spill out from the gap around the outlet. Male elderly people often have varying degrees of bronchitis and emphysema as well as prostate enlargement, which can lead to tension incontinence when coughing increases intra-abdominal pressure. Although holding urine can lead to the occurrence of these diseases, it is relatively simple to prevent them, as long as you drink more water and urinate more often, you can basically achieve the purpose of preventing the occurrence of these diseases. In addition, it is worth noting that young people should also try to avoid holding urine. If young people hold urine, it can also induce the above-mentioned diseases. I have seen some cab drivers, due to the special nature of their profession so that they do not dare to drink a lot of water to reduce the number of urination, while often have a long time to hold urine, often resulting in recurrent urinary tract infections and urinary stones. Therefore, we should develop the habit of drinking more water and urinating more often to speed up the excretion of metabolites in the body and prevent urinary tract infections and the occurrence of stones. Mahjong is a popular recreational activity for the elderly, but if you believe in “pee, lose a hang” and forcefully hold urine, it will lead to the occurrence of various diseases mentioned above. Therefore, we should promote healthy mahjong recreation, break the superstitious thinking, and truly entertain the body and mind and good health.
