What's wrong with kidney water?

The kidney is a metabolic organ of the human body. It eliminates waste and generates a certain amount of urine. After the kidney produces urine, it needs to pass through the ureter to reach the bladder and pass through the urethra to be discharged. In the process of discharge, obstruction is caused. After the formation of compression, long stones, long tumors cause obstruction, and urine is not unobstructed, it can cause ponding. The survival time after ponding needs to be analyzed according to the cause and treatment of ponding.
