Differentiation and Treatment of Urinary Tract Infection based on the Theory of 'Seminal Orifice' / 中医杂志

ABSTRACT

In the differentiation and treatment of recurrent urinary tract infection （rUTI） from the perspective of the seminal orifice， it is proposed that the urinary tract belongs to the category of "seminal orifice"， and the physiological process of urination is closely related to the function of the seminal orifice. From the three dimensions of orifice body， orifice pivot and orifice spirit， the physiological relationship between seminal orifice and the function of five zang-organs （脏） is constructed， that is， lung heat， yin damage and pathogen counter-restriction lead to malnutrition of orifice body； burning heart fire and spirit disorder lead to unfavorable orifice spirit， and kidney deficiency， liver constraint and spleen stagnation lead to unfavorable orifice pivot. In the early stage of rUTI， there is usually unfavo-rable orifice pivot， for which the treatment principle should be treating the root and the branch simultaneously， consi-dering both deficiency and excess， and paying attention to the management of accompanied symptoms. Zishui Qinggan Beverage （滋水清肝饮） and Modified Shenzhuo Decoction （肾着汤加减） are often selected based on syndrome differentiation. In the middle stage， lack of nourishment of the orifice body and unfavorable orifice spirit and pivot coexist， and the treatment should be draining the orifice and unblocking strangury， commonly withmodified Qingxin Lianzi Beverage （清心莲子饮）. In the late stage， loss of nourishment of the orifice body is the main pathogenesis， and it is necessary to further nourish the orifice body to prevent recurrence， and modifed Wuzi Yanzong Pills and Erxian Decoction （五子衍宗丸合二仙汤） is often used. Furthermore， the specific medicinals should be selected targeting at the orifice body， orifice pivot， and orifice spirit， so as to nourish orifice body by dispelling external pathogens and rectify healthy qi， to drain orifice pivot by freeing emotions and minds and unblocking qi movement， and to calm orifice spirit by unblocking heart and kidney and nourishing heart spirit.
