Why does holding urine cause kidney pain?

Under normal circumstances, holding urine for half an hour will not cause kidney pain. Once this phenomenon occurs, it means that there is something wrong with the kidneys, bladder and other organs. The main reason is that it is directly related to holding urine for a long time, and finally kidney pain occurs due to hydronephrosis. In addition, holding urine for a long time can also lead to decreased kidney function and sexual function, urinary tract infection and other diseases. It can be seen that the harm of holding urine is very great.

1. What causes kidney pain when holding urine?

Holding urine for a long time will cause urine to accumulate in the bladder. When the urine in the bladder reaches the upper limit of normal capacity, the detrusor muscle of the bladder will over-expand. Long-term accidents will lead to weak contraction of the detrusor muscle of the bladder and increasing pressure in the bladder, causing urine to flow back into the ureter and even the renal pelvis, causing hydronephrosis. Once hydronephrosis occurs, kidney pain will occur.

2. The harm of holding urine for a long time

1. Cause urinary tract infection: Holding urine for a long time will prevent the bacteria in the urine from being excreted in time. In the long run, it is easy to cause diseases such as cystitis and urethritis.

2. Impact on kidney function: Holding urine for a long time may cause urinary tract infection. Once urinary tract infection occurs, in severe cases, the inflammation will spread upward to the kidneys and affect kidney function.

3. Impact on sexual function: Since the male reproductive system and urinary system are controlled by the same group of nerves, holding urine for a long time will cause excessive pressure on this group of nerves. Once this group of nerves becomes disordered, it may not only cause kidney pain but also affect sexual function.

Holding urine frequently is very harmful. It will not only cause hydronephrosis and lead to swelling and pain in the kidney area, but also affect kidney function and even sexual function. Therefore, everyone should urinate in time in daily life and do not hold urine. If you develop some disease due to holding urine for a long time, you should go to the hospital for treatment in time to avoid affecting your health.

However, kidney pain caused by holding urine is not necessarily a symptom caused by kidney stones. Therefore, patients with kidney pain caused by holding urine are advised to go to a regular hospital for a routine urine test to determine the root cause, and then receive symptomatic treatment to eliminate the adverse symptoms of kidney pain caused by holding urine. In addition, kidney pain caused by holding urine may also be caused by chronic renal failure.
