Cavernotomy in renal tuberculosis. Seven cases. Review of the literature.

During the period 1957--1973 the author treated 7 cases of renal tuberculosis where cavernotomy was performed. Some views presented in the literature concerning the development and the detrimental effects of renal cavities are discussed. The diagnosis is purely radiological. Because of impaired renal function, drip infusion urography is recommended for such cases. The indication for operation is an isolated focus near the renal surface containing active tuberculosis with presence of tubercle bacilli. Vascular circulation is impaired locally and renal function diminished. This consitutes a latent danger for the host. The present findings are discussed and compared with results from the literature.
