Traditional Chinese Medicine Definition

Lithuria, also known as urinary tract infection, is a category of kidney-related diseases in traditional Chinese medicine. According to the "Internal Medicine of Traditional Chinese Medicine," lithuria is characterized by frequent urination, dribbling pain, acute lower abdominal cramps, or pain radiating to the waist and abdomen. The etiology and pathogenesis are often attributed to the accumulation of damp-heat in the lower jiao, leading to an obstruction in the transformation and excretion of urine by the bladder.

In TCM clinical practice, the core pathogenesis of Lin Zheng is accumulation of damp-heat and impaired Qi transformation of the bladder. Common triggers include irregular diet, emotional distress, and overexertion. During syndrome differentiation, attention should be paid to distinguishing cold, heat, deficiency, and excess of Lin Zheng:

1. Heat strangury: Manifested as frequent urination, burning and stabbing pain, dark yellow urine, mostly caused by accumulation of damp-heat.
2. Stone strangury: Manifested as difficult urination, sand or stones in the urine, or sudden interruption of urination, mostly caused by prolonged accumulation of damp-heat leading to stone formation.
3. Qi strangury: Manifested as lower abdominal fullness, difficult and dribbling urination, mostly caused by Qi stagnation and impaired bladder Qi transformation.

Overall direction of regulation: In TCM clinical practice, treatment mainly focuses on clearing heat and draining dampness, unblocking strangury and expelling stones, and regulating Qi to dredge. Through syndrome differentiation and treatment, regulating the Yin-Yang balance of the body and restoring the Qi transformation function of the bladder can achieve the therapeutic goal. Traditional Chinese medicine holds that treatment should flexibly apply herbal formulas based on the specific syndrome type to achieve the best therapeutic effect.

Qi Lin

Main Manifestations: Abdominal distension and fullness, difficult urination, dribbling and not expressed

Management Approach: Regulate Qi and promote circulation, diuretic and relieve stranguria

The above syndrome information is based on traditional Chinese medicine textbooks and clinical standards. Specific differentiation should be completed by a practicing traditional Chinese medicine physician in person.
