The pain of kidney stones is mainly related to the blockage of the ureter by the stone, which leads to hydronephrosis of the renal pelvis or renal calyx, local mucous membrane damage or infection, and it is recommended that the patient consult the doctor in time for treatment.
1. Stone blockage of ureter: when kidney stone dislodges and enters into the ureter, it can lead to different degrees of obstruction and friction in the ureter, causing spasm of the smooth muscle of the ureter, which leads to pain. This kind of pain is also known as renal colic, which is manifested as severe colic pain in the lower back.
2. Causing hydronephrosis in renal pelvis or calyx: if kidney stones block the renal pelvis and calyx, resulting in hydronephrosis, the urine produced by the kidneys will accumulate in the kidneys and be difficult to be discharged, which leads to an increase in the pressure of the renal pelvis and calyx, and the pain is caused by the stretching of the renal peritoneum, which may be accompanied with nausea, vomiting and other symptoms.
3. Local mucous membrane damage or infection: kidney stones can easily lead to local mucous membrane breakage, bleeding, or even secondary local infection, which will lead to local inflammatory reaction and pain, and can be accompanied by frequent urination, urinary urgency, blood in urine and other manifestations.
Kidney stone pain may also be caused by other factors, it is recommended that patients go to the regular hospital in a timely manner to seek treatment, and strive for early recovery.
