After the formation of kidney calculi, if the surface is smooth and fine, it can be excreted with urine, and patients will not have obvious discomfort symptoms. In addition, if stones are fixed in the renal pelvis and inferior calyx without inducing infection, the patient may not feel anything. Even if it is a large stone, if it does not cause obstruction or infection, it has no symptoms, or only slight kidney discomfort and pain.
In addition, if the stones are large or infected, patients will have different degrees of abnormal performance. Especially when the following four symptoms appear, it may be a signal reported by kidney calculi:
1, pain in renal area
If the stone is located in the renal pelvis or calyx, and it grows larger, it will cause oppression and friction, or it will cause symptoms of hydronephrosis, which will lead to symptoms such as swelling or dull pain in the renal area. In addition, if the stone is small and moves in the renal pelvis or ureter, it will stimulate the ureter, thus causing "renal colic".
Symptoms of renal colic often appear suddenly, especially in the middle of the night, patients will wake up in an instant, and the pain is unbearable. The pain starts from the back or flank, and then radiates along the ureter to the lower abdomen, people inside and outside the thigh, and vulva, accompanied by dysuria, nausea and vomiting, sweating and other abnormal manifestations.
2, hematuria
Hematuria is the main manifestation of kidney calculi. Kidney calculi can induce hematuria because the mucosal tissue of the kidney is rubbed by stones. This symptom is often accompanied by renal colic, and obvious hematuria can be seen with the naked eye.
There are also a few patients who have no pain, mainly hematuria or extremely small blood volume, which can not be seen by the naked eye. In urine examination, we can see that the number of red blood cells in urine is abnormally increased, which is also one of the indicators for diagnosing kidney calculi.
3, infection performance
Some patients will have different degrees of infection, even pyuria. When they are infected, they will have chills, fever, backache and other symptoms. , especially "high fever". After taking antipyretics, there will be a brief fever, but then the body temperature will rise.
4. Dysuria
If it is only unilateral kidney calculi, it may cause one side urinary tract obstruction, leading to dysuria. If there are stones in both kidneys, it will cause bilateral urinary tract obstruction. In addition to dysuria, it may also cause symptoms of urinary incontinence, that is, no urine is discharged. This is also the most dangerous performance. If not treated in time, it may also cause renal function damage and even acute renal failure.
If a strange pain suddenly appears in one lower abdomen, accompanied by nausea, vomiting, sweating and other symptoms, it is a typical signal of kidney calculi's arrival, and it is necessary to see a doctor and check the kidney in time.
If the stone is too big to be excreted with urine, it should be removed at the doctor's suggestion to ensure that the renal function is not damaged.
