When the stones are small and can be expelled directly, the patient’s symptoms are not obvious, but when the stones are large, there will be obvious symptoms. There will be some uncomfortable feeling before the kidney stone is expelled naturally, such as pain, feeling of holding in urine, etc. Once the kidney stone is formed, there will be no obvious symptoms.
Once the kidney stone is formed, there will not be very obvious symptoms, and there will not be specific symptoms when it is to be discharged in the lower or middle calyces, but when the stone continues to move downward and passes through the three narrowings of the ureter, there will be obvious sensations.
Usually there is only a slight discomfort at the beginning, and then gradually there will be severe pain, the feeling of holding urine, and even accompanied by oliguria, anuria and hematuria. Pain occurs at each stenosis, and after the stone passes through the stenosis and the ureter is unblocked, the patient’s pain is relieved, but then the pain occurs again at the next stenosis. The two states alternate. When the stone reaches the bladder, there may be a feeling of diarrhea due to irritation of the vesico-rectum.
