Renal colic is one of the common early symptoms in kidney calculi. If kidney calculi appears at the junction of renal pelvis and ureter, or descends in ureter, sudden renal colic often occurs. This kind of pain is like a knife, and patients are often unbearable. At first, the pain is located on one side of the abdomen or waist, and then it will spread down to the vulva and the inner thigh of the bladder area. Some patients will be accompanied by symptoms such as nausea, vomiting and sweating.

2, gross hematuria

After suffering from kidney calculi's disease, early symptoms of gross hematuria may appear, mainly due to damage of renal mucosa. Stones are hard, which may cause serious damage to the existing mucosa during continuous activities, especially when patients have a large amount of activities. If there is infection, there will still be pus cells in the urine, accompanied by urgency and pain.

3. Waist mass

After suffering from kidney calculi, it may cause hydronephrosis. If it is severe hydronephrosis, it will often form a waist lump, and the waist or upper abdomen can feel the lump.

4, a dull pain in the waist

If kidney calculi is relatively large, or the number of kidney calculi is relatively large, there may be a dull pain in the waist, which is usually accompanied by hematuria after strenuous exercise.
