Bladder biopsy in the diagnosis of urogenital tuberculosis

: The authors report 5 cases of urogenital tuberculosis where examination of the urine failed to reveal any B.K. The diagnosis was suggested by the history of tuberculosis and the radiological appearance by intravenous pyelography. However, it was not possible to start an antituberculosis therapy in the absence of bacteriological proof. Forceps biopsy for histological examination provides an additional argument: the highly typical tuberculosis granuloma.
