The incidence of subclinical forms of urogenital tuberculosis in patients with pulmonary tuberculosis

Abstract

The aim of our study was to determine whether patients with pulmonary tuberculosis may have subclinical forms of urogenital tuberculosis.Between 2011 and 2012, a prospective study was conducted. Basic demographic parameters were recorded and the following investigations were performed: direct bacilloscopy of sputum, evaluation of affected lung fields and presence of cavities on chest X-ray, Mantoux tuberculin skin test II, and interferon gamma release assay. Culture and molecular methods for Mycobacterium tuberculosis in urine were performed. In cases with a positive urine test, an ultrasound examination, computed tomography scan of the abdomen, and endoscopy of the urinary tract were performed.A total of 102 patients (75 men and 27 women) were included in the study, with a median age of 46.8 years. Subclinical forms of urogenital TB were detected in 7 patients; 5 by molecular methods, 1 by urine culture, and 1 with both methods The presence of subclinical forms of genitourinary TB was found in 4 patients without and 3 patients with findings on imaging methods corresponding to TB.A significant number of patients with pulmonary tuberculosis may simultaneously have subclinical forms of urogenital TB.
