[Relation between pulmonary tuberculosis and the urinary tract].
We have studied 48 children that presented lung tuberculosis together with the effects tuberculosis has on the urinary apparatus. Clinical, laboratory and radiotherapeutic studies were made in order to confirm the diagnosis which was etiologically confirmed in only two cases. In order to make a good diagnosis it is necessary to use a good technique for urine collection with serial cultures corresponding to four consecutive days and the radiological study of the kidney and its afferent ducts. It is an illness more common than what is thought. It is necessary to know how to detect it and it is very important to have it "in mind" when dealing with any generalized tuberculosis disease: (miliary tuberculosis, meningoencephalitic tuberculosis, etc.). With this article, it has been our purpose to contribute to review and to bring up to data the clinical and pathophysiological concepts of this disease.
