The changing pattern of renal tuberculosis

Abstract

The authors present a series of 2,173 patients with renal tuberculosis seen between 1950 and 1979. This is group 1, serving only to show the incidence of renal tuberculosis during the antibiotic era. The fact is that the incidence of renal tuberculosis is going down slightly but constantly in the last years because the resistance of patients is increasing and the virulence of the TB bacillus is decreasing. The second group consists of 128 patients completely examined and the conclusion is that certain forms of very active TB have disappeared; high fever, very active forms of renal TB with deep and limited ulcerations in the kidney do not occur anymore. The third group is formed of 208 patients reviewed in order to demonstrate the residues after long antituberculotic treatment. It has been found that certain residual changes in the parenchyma are minimal but present as the remnants of antibiotic treatment indicating that probably the bilateral forms of renal TB are more common than we supposed before, in full agreement with Cibert's claim.
