A method and apparatus for treating urinary tract infections in females is described. In this state, a voltage on a pulse drive line is caused to fall. In this way, a noise current caused by high-frequency noise generated from the first or second circuit flows into the low impedance voltage output circuit. The upper portion of the mandrel includes a shear portion that is breakable by pulling upwardly upon the mandrel. The computer, in turn, compares the fixed value to a respective expected value. Each of the two coupling paths includes at least one capacitor and an inductor connected in series.
