Have you ever held your urine? How long did you hold it for?

Recently, #How harmful is it to hold urine for a long time# has become a hot search topic, and many netizens have left comments:

Nagging***: I am holding back and brushing it

Wild ***: I used to love playing online games, drinking beverages and holding my urine, which caused me to develop urinary stones.

**Sweet talk: There is no toilet at work. Every time I go to the toilet, I have to walk a distance to the mall. I have urinary tract infection and cystitis. It is so uncomfortable.

** He Nian: It is true that holding back can cause urinary tract infection

…

Just a while ago, the well-known game blogger Marco Abolosaidon also posted that he held his urine so hard from staying up late to play The Legend of Zelda that he urinated blood, and his red blood cell and white blood cell counts exceeded the standard by 200-300 times.

"Holding urine, especially for a long time, can cause damage to bladder function, cause urinary tract infection, prostatitis, induce bladder cancer, etc." Wang Kanger, deputy chief physician and deputy director of the Urology Department of the Affiliated Hospital of Hangzhou Normal University, mentioned, "Hematuria is one of the hazards of holding urine. When holding urine continuously, the bladder is always in a state of high pressure, and the local immune function of the bladder will be affected, which is prone to urinary tract infection and hematuria; at the same time, after holding urine, due to the high pressure in the bladder, urine can flow back to the kidney through the ureter, bringing bacteria from the bladder into the kidney, causing pyelonephritis, fever, low back pain and other symptoms, and even shock or death due to urinary sepsis in severe cases. In addition, when a large amount of urine is discharged all at once after holding urine continuously, the pressure in the bladder drops rapidly, and the capillaries expand and rupture due to the sudden drop in pressure, resulting in decompression bleeding, which is redder and more severe."

Of course, it is not a given that hematuria is caused by holding urine. Wang Kanger said that for some hematuria, holding urine is just a superposition of accidental factors. In fact, there are nearly 60 diseases that can manifest as hematuria. Hematuria, especially painless hematuria, needs to be taken seriously. Once discovered, it is necessary to go to the hospital's urology department for a professional evaluation, focusing on excluding malignant diseases such as bladder, ureter and kidney tumors, so as not to delay the disease.

Common diseases in urology

Almost every day, we see patients with hematuria.

Wang Kanger said that the human body generally excretes 2000-2500 milliliters of urine a day. "Under normal circumstances, the bladder generally stores one milliliter of urine per minute, and about 60 milliliters per hour. Men usually need to go to the toilet when the bladder capacity reaches 200-250 milliliters, while women have a slightly stronger ability to hold urine, and usually go to the toilet at around 250-300 milliliters."

But it is not absolute. "Our breathing, sweating, and defecation all bring out water. In the hot summer, the body consumes a lot of water and sweats a lot, so the amount of urine will be less than in the winter, and the number of times you urinate in a day may also decrease accordingly."

Wang Kanger's clinic sees some patients with hematuria almost every day. After careful inquiry into the causes, it is found that many of them have a history of holding urine, and many of them are related to their occupations, such as workers who cannot get off the assembly line, long-distance truck drivers, those who work far from the toilet, those who are immersed in playing mahjong and holding urine, etc.

Wang Kanger once treated a female patient in her 40s who came to see him because of frequent, urgent and painful urination. She had acute cystitis and hematuria. After careful questioning, it was found that this patient often held her urine while playing mahjong, as she wanted to win the game without going to the toilet. Once she held it for more than five hours and was scared to death by the blood-red urine when she went to the toilet, so she rushed to the hospital for treatment.

Wang Kanger said that hematuria caused by holding urine can be caused by two reasons: one is secondary infection, in which the mucosa becomes eroded, damaged and bleeding; the other is decompression bleeding, in which the bladder pressure is suddenly released, causing massive diffuse bleeding in the capillaries.

"Generally speaking, don't worry too much if you find blood in your urine," Wang Kanger explained. "Most of the blood in your urine is urine, and the amount of bleeding is actually very small. An experiment has shown that if you inject less than 5 ml of red liquid into 1000 ml of water, the color will look quite red. The real bleeding is the kind with a lot of blood clots, which needs to be taken seriously. If only the urine looks red and there are no large blood clots, don't panic, you will have plenty of time to go to the hospital to see a doctor for treatment."

The bladder that holds urine is very fragile

"My bladder is going to explode!" Many people feel this way after holding their urine for too long. In fact, the possibility of bladder rupture caused by holding urine is very small, and it is more likely to cause damage to bladder function. However, once there is an external impact, such as falling, collision, or forceful coughing or sneezing, the bladder is likely to rupture.

"Now is the season for crayfish and beer. Many people drink too much, get high, and get drunk. Their bladders are full. If they fall or get kicked at this time, it is easy for their bladders to rupture."

Wang Kanger once treated a young man in his 20s who drank a box of beer and got drunk. He fell on the curb and developed symptoms such as hematuria and abdominal pain. He was sent to the emergency room of the hospital. Abdominal B-ultrasound found a large amount of fluid in the abdominal cavity. A bladder water injection test determined that the bladder was ruptured, so he underwent emergency bladder repair surgery.

From now on, don't hold your urine.

Wang Kanger said that frequently holding urine will keep the bladder full for a long time, which will cause the bladder contraction force to decrease, and then cause urination difficulties and urinary incontinence. At the same time, holding urine for a long time will increase the pressure in the bladder, causing the pressure in the kidneys to increase, making it impossible to urinate, causing hydronephrosis, and also leading to increased creatinine and impaired kidney function. "It is very important to develop good urination habits. First of all, you should urinate regularly. Secondly, drink more water to promote urination. Finally, develop the habit of urinating before going to bed." Wang Kanger reminded.
