Multiple calcified foci in the left kidney may be due to calcification of the renal papilla as well as old renal tuberculosis and other factors.
1. Calcification of renal papilla: If the renal papilla secretes urine, which produces calcium salt deposits, then calcified foci will also be found through examination.
2. Old renal tuberculosis: If you have had renal tuberculosis before, the scar left behind after the disease is cured will gradually form calcium deposits, so you will find calcified foci through examination.
If there are calcified foci found in the kidney through imaging examination, it is recommended to review kidney function and urine routine regularly to analyze whether there are lesions in the kidney and whether the kidney function is impaired, and treat the disease under the guidance of professional doctors.
