title: [Cystoscopy and endovesical biopsy in renal tuberculosis].
abstract: Cystoscopy and endovesical biopsy of the bladder wall were performed at early stages of investigation prior to the onset of tuberculostatic treatment in 77 patients with destructive renal tuberculosis, verified both bacteriologically and histologically. Cystoscopy proved to be valuable in 83.2% of the cases, particularly so where the destruction focus communicated with the renal calyx-pelvis system. Cystoscopic symptoms of renal tuberculosis occurred at the following rates: tubercles in 6.5%, focal hyperemia, in 18.2%, erosion and ulcer, in 9.1%, bullous edema of the ureteral opening, in 11.6%, all kinds of changes of ureteral opening, in 37.6%. There were no visible changes of vesical mucosa in 16.8%. The pattern of mucosal changes correlated with the markedness of X-ray morphological changes in the kidney. Endovesical biopsy was positive in 52%, its results, being significant in cases of open destructive developments and ureteral affection. The value of endovesical biopsy increased where it was performed at the peak of clinical and cystoscopic symptoms, at early stages of disease, before the onset of tuberculostatic treatment. False-negative results of endovesical biopsy do not exclude renal tuberculosis. High value of cystoscopy and endovesical biopsy makes them up-to-date diagnostic tests for renal tuberculosis.
