In tuberculosis of the kidney, bladder, or other part of the urinary tract, the feeding of the patient is a more difficult matter than in most other forms of tuberculosis. It is often impossible to give the amount of protein food desirable, because of the extra strain thrown on the kidneys by a diet rich in protein.

Special care has to be taken with the amount and nature of the animal protein foods given. Those meats should be given in carefully regulated amounts. Much assistance in framing the diet is derived from the examination of the urine. So long as the amount of protein being administered does not increase the amount of albumin or pus in the urine, the diet in use may safely be continued.

In general, it will be found that the most suitable diets for these cases are those indicated on p. 432. At the outset the lighter diet (p. 430) should be given; and if the condition of the patient and of the urine allow it, this may give place to the stronger diet on p. 424. In some cases it is necessary to largely ignore the state of the urine, and rather treat the general condition.
