Kidney stones usually do not cause high blood pressure, but if the stone blocks the urinary tract and leads to hydronephrosis, it can affect blood pressure or cause a transient increase in blood pressure when the pain is severe.
Hypertension is divided into primary and secondary. Primary hypertension is what we usually call high blood pressure, which is closely related to genetics and dietary habits. Secondary hypertension is high blood pressure caused by other diseases, common causes are primary aldosteronism, renal artery stenosis, pheochromocytoma, etc., which does not have kidney stones.
Kidney stone is one of the common diseases in urology, and the common symptoms include back pain, lumbar soreness and discomfort, and hematuria. In some patients, the stone slips into the ureter can lead to severe renal colic. Kidney stones blocking the urinary tract can also lead to hydronephrosis, which in severe cases leads to renal insufficiency.
Kidney stones affect blood pressure in the following two ways:
1. Kidney stones block the ureter, making urination poor, leading to hydronephrosis, causing reduced renal function, water and sodium retention and resulting in increased blood pressure. So you should actively treat it if you have hydronephrosis.
2. When renal stone induces renal colic, the pain induces sympathetic nerve excitation, with symptoms such as transient blood pressure increase and tachycardia.
In general, kidney stones usually do not cause high blood pressure. Patients with kidney stones should drink plenty of water, exercise regularly, seek timely medical attention and active treatment to promote the discharge of stones to prevent chronic damage to the kidneys.
