Calculusofkidney refers to stones that occur in the renal calyces, renal pelvis, and the connection between the renal pelvis and ureter. Most of them are located in the renal pelvis and calyces, while parenchymal stones are rare. Plain films show single or multiple round, oval or blunt triangular dense shadows in the kidney area with high and uniform density and smooth edges, but some are not smooth and mulberry-shaped. The kidney is the main site of urinary tract stone formation, any other parts of the stone can originate from the kidney, ureteral stones almost all come from the kidney, and kidney stones are more likely to directly damage the kidney than any other parts of the stone, so early diagnosis and treatment is very important.

Patients with kidney stones may occasionally seek medical attention for painless hematuria, but there are also patients with mainly pain and no hematuria. 3, the history of stone removal: kidney stones in the urine of patients are sweepable sand and stones, especially in the pain and hematuria episodes, mixed with sand or small stones in the urine. For those who have pain and hematuria suspected of kidney stones, if the X-ray film does not see the influence of calcification, the patient should be asked to intimately observe whether there are sand and stones discharged with the urine. 4, other symptoms: kidney stones common complications are obstruction and infection.
