Kidneys don’t usually show fluid buildup when you drink too much water. The kidneys will form urine out of the body from the excess water, and generally will not accumulate in the kidneys to form fluid.
The main function of the kidneys is to form urine. After drinking a lot of water, the body’s blood volume increases. The kidneys will convert the excess water into urine to be excreted from the body through the ureter, bladder, and urethra.
Fluid accumulation in the kidneys is also known as hydronephrosis, which occurs mainly due to urinary tract obstruction, such as ureteral stones, ureteral stenosis, prostatic hyperplasia, neurogenic bladder and other factors leading to blockage of the urine discharge channel, and the urine will accumulate in the kidneys and form fluid accumulation.
If you have hydronephrosis, you need to pay attention to it, and it is recommended that you go to the regular hospital in time to have a checkup, to clarify the reason for the formation of hydronephrosis and the degree of hydronephrosis, and then follow the doctor’s instructions to carry out targeted treatment.
