Kidney stones often have clinical manifestations such as back pain, pain in the lower ribs, pain when urinating, the patient may have frequent urination, urinary incontinence, even blood in the urine,... However, the above symptoms can also occur in other diseases. Therefore, it is impossible to rely solely on clinical symptoms to diagnose kidney stones, but it is necessary to conduct an examination and perform paraclinical tests for kidney stones to detect kidney stones.

Currently, there are many methods to examine kidney function and the urinary tract in general. Among them, renal ultrasound is a familiar and widely used technique. In addition, scintigraphy is also a nuclear medicine test commonly used in clinical practice, but it is more complicated and less known.
