[The validation of the adequacy of chemotherapy in bladder tuberculosis based on a study of bacteriostatic activity]

Study of the bacteriostatic activity (BA) of the blood, urine and tissue of the tuberculosis-affected urinary bladder after the administration of two tuberculostatic combinations (isoniazid + cycloserine and isoniazid + rifampicin) has demonstrated the difference in the BA curves that were formed in the above media. Use of isoniazid + cycloserine gives rise to a high BA level by 6-9 h with further gradual decrease of the parameters. The combination of isoniazid + cycloserine produces a typical double-humped curve with titre prolongation. The data obtained give evidence on the experience of the use of the first combination of the preparations in patients with fresh circumscribed urinary bladder lesions. The second combination (isoniazid + rifampicin) is indicated in the presence of ulcerous-cicatricial changes in association with a more prolonged circulation of the preparations in the organism (specific features of rifampicin metabolism).
