KIDNEY - Tuberculosis

The kidney shows extensive foetal lobulation, apparent on the outer surface, while the cut surface shows almost complete destruction and replacement by caseous foci; the central part of these foci contains greenish pus. There is very little renal parenchyma apparent.
This man had bilateral renal tuberculosis diagnosed in 1971, and was treated with anti-tuberculous therapy. Clearly, he failed to respond, and ultimately went into renal failure. In 1976, this kidney was removed; at some later stage the second kidney was removed, and he has been treated subsequently by dialysis. In March 1978, he was still on home dialysis and working.
