The length of life of a patient with renal tuberculosis depends entirely on whether it is cured or not. Originally, since anti-tuberculosis drugs were not available, tuberculosis was considered a terminal disease. Since the emergence of anti-tuberculosis drugs, most of the renal tuberculosis can be cured, so naturally, the life expectancy of patients with renal tuberculosis will not be affected. For some other patients with renal tuberculosis, the treatment may be untimely or delayed or may not be sensitive to anti-tuberculosis drugs, the renal parenchyma to the destruction of the more obvious, and gradually appeared in the decline of renal function, and finally developed into uremia. The life expectancy of this part of the patient will naturally be affected, and the survival period may not exceed 10 years. Because tuberculosis can easily involve multiple organs, such as pulmonary tuberculosis and renal tuberculosis at the same time, the survival time may be even shorter, may be a few months to a few years because of respiratory failure and death.
