Kidney stones may develop into uremia, which is often seen in bilateral kidney stones, causing fluid retention in both kidneys, the kidney function will gradually lose, and ultimately the manifestation of uremia, so when the patient exists with stones, need to go to the hospital for early treatment. Stone-induced uremia is often due to stone-induced obstruction of the urinary tract, the urine produced by the kidneys is blocked from being discharged, it will accumulate in the kidneys to form hydronephrosis. When the amount of hydronephrosis gradually increases, it will exert pressure on the renal parenchyma, resulting in the loss of effective renal units, a gradual increase in kidney volume, a gradual thinning of the renal cortex, and a gradual loss of effective renal units, which irreversibly damages the function of the kidneys. If such lesions occur bilaterally at the same time, renal insufficiency and uremia stage will be manifested. Early detection and early treatment are effective measures to prevent kidney stones from further leading to renal insufficiency. The most important purpose of removing stones is to relieve the urinary tract obstruction caused by the stones, so that the urinary tract can restore its patency and further hydronephrosis and its further renal function damage will not occur.
