Kidney stones are stones that occur in the renal calyces and renal pelvis and in the junction of the renal pelvis and ureter. Most of the stones are located in the pelvis and calyces, while parenchymal stones are rare. Plain films show single or multiple dense shadows in the kidney area, and ultrasound shows strong echogenic clusters with acoustic shadows.
The kidney is the main site of stone formation in the urinary tract. Stones from any other part of the body can originate in the kidney. Ureteral stones almost always come from the kidney, and kidney stones are more likely to damage the kidney directly than stones from any other part of the body. When stones block the ureter or renal pelvis, they can cause renal colic. Long-term chronic stone blockage can cause sick kidney insufficiency or non-functioning, such as single or double kidney stones, which can seriously lead to uremia and require dialysis treatment or kidney transplantation.

Therefore, early diagnosis and treatment are very important, do not take it lightly!
Nowadays, treatment is mainly based on minimally invasive treatment, and more than 90% of stones do not need to be operated.
