Recurrent UTI (Heat Strangury)
Overview
Heat strangury (re lin) is a type of strangury disorder characterized by frequent, scanty, urgent and painful urination with yellow or reddish urine. Recurrent cases are often due to damp-heat accumulating in the lower jiao, or chronic illness damaging the spleen and kidney, leading to a pattern of healthy qi deficiency with lingering pathogens. The disease is located in the bladder and kidney, involving the liver and spleen. Early stages are usually excess patterns of damp-heat pouring downward, impairing bladder qi transformation; recurrent episodes consume qi and yin, resulting in mixed deficiency and excess. Treatment focuses on clearing heat, draining dampness and relieving strangury, while also strengthening the spleen, supplementing the kidney, nourishing yin and boosting qi. Recurrent UTI falls under this category; identifying triggers such as fatigue, emotional stress, and improper diet is important.
Pattern differentiation (clinical patterns)
Damp-Heat Pouring Downward
Frequent, scanty, urgent and painful urination with burning sensation, yellow-red turbid urine, distending pain and tightness in the lower abdomen, bitter and sticky taste in the mouth, possibly fever, red tongue with yellow greasy coating, and a slippery rapid pulse.
Clear heat, drain dampness, and relieve strangury.
Spleen-Kidney Qi Deficiency
Frequent urination with incomplete emptying, episodes triggered by fatigue, mental fatigue and lack of strength, soreness and weakness of the lower back and knees, poor appetite, pale tongue with thin white coating, and a deep, thin, weak pulse.
Strengthen the spleen, supplement the kidney, boost qi, and relieve strangury.
Kidney Yin Deficiency
Scanty dark urine with difficult urination, recurrent episodes, soreness and weakness of the lower back and knees, five-center heat (heat in palms, soles, and chest), dry mouth and throat, red tongue with little coating, and a thin rapid pulse.
Nourish yin, supplement the kidney, clear heat, and relieve strangury.

Daily care & prevention
Drink plenty of water, at least 2000 mL daily, urinate frequently and avoid holding urine. Maintain perineal hygiene and urinate after intercourse. Eat a light diet, avoiding spicy, greasy, and alcoholic beverages. Avoid overwork and exposure to cold; keep a calm mood. Consume damp-draining foods such as adzuki beans, coix seed, and winter melon. During acute episodes, rest and complete the full course of medication as prescribed; do not stop early to prevent recurrence.
When to seek medical care
High fever with chills, severe low back pain, nausea and vomiting suggest progression to pyelonephritis; blood clots in urine or worsening dysuria; oliguria, edema, elevated blood pressure; confusion or hypotension indicating sepsis; worsening symptoms in pregnancy or diabetes—seek immediate medical attention.
