The site of stone pain needs to be judged according to the organ in which the stone appears, and the common site of stones is in the urinary system, including kidney stones, ureteral stones, bladder stones, gallstones, etc. The above stones usually cause pain in different locations: 1. Kidney stones: kidney stones are mainly manifested as pain in the lower back, and larger stones are more fixed in position, so patients often have no pain or less pain, or may show hidden pain or dull pain. Smaller stones can move at will, causing severe renal colic, mostly late at night, starting with the lower back, radiating downward to the bladder, male patients also have testicular pain, making patients appear pale, restless, can be accompanied by nausea, vomiting and other symptoms; 2, ureteral stones: ureteral stones pain can be manifested as renal colic, with sudden pain in the lower back and gradually aggravated, male pain can be radiated to the penile area The pain can be radiated to the penis in men and to the labia in women, and patients can also have symptoms such as hematuria, painful urination, nausea, vomiting, etc.; 3. Gallstones: stones are usually formed in the gallbladder and bile ducts, and most patients have no symptoms, which may also manifest as right upper abdominal cramps. Gallbladder stones present as severe bouts of pain in the right upper abdomen, which may radiate to the right shoulder or back, as biliary colic, along with significant tenderness in the right upper abdomen. Extrahepatic bile duct stones manifest as right upper abdominal colic, but intrahepatic bile duct stones often have no obvious symptoms.
