Holding urine for a long time will make the urine in the bladder accumulate more and more. If the urine containing bacteria and toxic substances can not be discharged in time, it is easy to cause cystitis, urethritis and other diseases. Serious, urinary tract infection can also spread to the kidney, causing pyelonephritis, and even affecting renal function.
Holding urine is one of the causes of prostatitis. In the low temperature environment, the excitability of the sympathetic nerve of the prostate will be significantly enhanced, which will cause the contraction of the prostate gland, causing chronic congestion and increasing the pressure in the urethra. The change of urethral condition will aggravate the deposition of prostatic fluid, which will lead to the attack of prostate disease, and make the patients have the symptoms of frequent urination, urgent urination, nocturia, dysuria, perineum and testicular pain. Especially for many old patients, the condition will be aggravated or repeated with the decrease of temperature.
Male reproductive erection and urinary system are controlled by the same group of nerves. When people hold urine for a long time for a long time, this group of nerves will bear excessive pressure. Once this group of nerves appear disorder, it is not only urine pain, urine obstruction and other problems, when it will also cause a series of male sexual dysfunction such as impotence, thus affecting fertility
Data from abroad indicate that the frequency of micturition is closely related to the incidence rate of bladder cancer. The less urine frequency, the greater the risk of bladder cancer. Because holding urine increases the action time of carcinogens in urine on the bladder, people who have the habit of holding urine are 3-5 times more likely to have bladder cancer than ordinary people.
The nerves controlling bladder contraction are distributed in the muscles of bladder wall. If the bladder is held for too long, the nerve will be damaged due to ischemia or excessive pulling, resulting in painful urination, frequent urination or unclean urine. If the nerve damage is serious, bladder sphincter is weak, even can cause the consequence that can't discharge urine.
