[Prevention and treatment of recurrent urinary tract infection with a yishenkang granule]

In this study, 35 female adult patients who were married and suffered from recurrent urinary tract infection in remission stage with the type of the deficiency of Kidney-Qi ( ) were admitted as the objects for this study. Before and after treatment, the T lymphocyte subtype of peripheral blood (OKT3, OKT4, OKT8), serum immunoglobulins (IgG, IgA, IgM, IgD), urinary sIg (sIgA) were performed by the ways of monoclonal antibody technique and radio-immunity analysis. The results proved that disturbances of cell mediated immunity, humoral immunity and local immune function were involved in the pathogenesis of the disease. These changes might be one of the susceptible factors that caused the repeated attacks of the disease, and the internal pathological basis of Kidney-Qi deficiency type. After taking Yishenkang granule according to the principle of benefiting Qi and invigorating the Kidney, the patients had been restored fairly from the disease on the low levels of the immune function, and strengthened on anti-infectious ability. From these, the attacks of the disease had been controlled effectively. The curative rate had reached 68.6%.
