Screening for tuberculosis in the study of the living renal donor in a developing country.

Given the high prevalence of tuberculosis (Tb) in the Mexican population, a strict program to detect Tb in the potential donor is required. Chest x-ray, excretory urogram, urinalysis with microscopic exam of the sediment, urine cultures for M. tuberculosis, and tuberculin skin test (TST) with PPD-RT23 performed for evaluation of 222 living donors were reviewed.
