Six-month chemotherapy for urogenital tuberculosis.

Rifampicin (RMP, 600 mg), isoniazid (INH, 300 mg) and pyrazinamide (PZA, 1,000 mg) administered daily in the hospital for a duration of 2 months was followed at home by daily administration of 600 mg RMP and 300 mg INH for a duration of 4 months. 113 patients with previously untreated and bacteriologically proven urogenital tuberculosis were admitted to the study. Therapy was completed and evaluated in 106 (94%) patients. No failure of chemotherapy was observed during the treatment; one bacteriologically proven relapse occurred after completion of treatment within the 45- to 63-month follow-up. This 6-month chemotherapy seems as efficient as the standard treatment which lasted for 18-24 months.
