Kidney calculi can cause low back pain, especially when kidney calculi is large or has obstruction, and the symptoms of low back pain are more obvious.

Patients with kidney calculi's disease, if they are large enough to oppress the surrounding tissues or kidney calculi's activities, will get stuck in the ureter, resulting in hydronephrosis and swelling and pain in the waist.

If it is a relatively small kidney calculi activity, it may lead to renal colic, mostly because kidney calculi will suddenly block the renal pelvis or ureter, causing obstruction, stimulating pain receptors and causing pain. In addition, the stone itself will also stimulate the kidney, leading to the release of pain media, which in turn will cause pain.

Generally speaking, in the absence of activities, kidney calculi will not have renal colic, and the pain caused by it is mostly dull pain or swelling pain, and the general position is relatively fixed, but the pain may be aggravated after stone activities.

After suffering from kidney calculi's disease, in addition to the pain symptoms, it may also be accompanied by abdominal distension and pain, hematuria and other symptoms.
