RESUMEN
Genitourinary tuberculosis is the second most common form of extrathoracic tuberculosis. The most common signs are persistent sterile pyuria in up to 90 of patients, irritative voiding symptoms and painless hematuria in up to 80 of the patients. In Puerto Rico the incidence of tuberculosis is rising, being 9.2 per 100000 population in 1992. A.I.D.S. has had a steady rise since 1983. With the rise in the incidence of both diseases and with the influx immigrants from countries were tuberculosis is endemic we should expect a rise in the number of cases of genitourinary tuberculosis. Chemotherapy is the mainstay of treatment. Surgery is performed less often. Early recognition and management is important to avoid irreversible damage to the genitourinary tract. The cases of a 43 y/o man and a 30 y/o male with A.I.D.S. are discussed
