Urinary Strangury (Lin Syndrome)
Urinary Strangury (Lín Zhèng)
Characterized by discomfort during urination with symptoms of urgency, increased frequency, oliguria, and painful, difficult urination. Additional symptoms may include fever and lower abdominal spasms or pain radiating to the lower back during urination. Note: pain is not always experienced with urinary strangury.
Relevant Biomedical Diseases
-Acute or chronic UTI to (cystitis, urethritis)
-Urinary renal calculi
-Neoplasms of the bladder, prostate, and urethra
Etiology and Pathology
Urinary strangury can be categorized according to six types depending on pathogenesis and clinical manifestations:
Heat strangury (rè lín):
Stone strangury (shí lín):
Qi strangury (qì lín):
Qi stagnation or Qi vacuity
Blood strangury (xuè lín):
Cloudy strangury (gāo lín):
Taxation strangury (láo lín):
difficult urination with dribbling
Exogenous Damp-Heat invades the Urinary Bladder via the Tai Yang (BL) channel, the leg Yin channels, or the local luo/collaterals of the genitourinary system.
Diet of greasy, spicy foods and alcohol can generate Damp-Heat in the Middle Jiao that, over time, will pour down into the Urinary Bladder.
Complications of Damp-Heat:
-Long-term Damp-Heat in the Lower Jiao may condense fluids and create urinary stones.
-Heat or Damp-Heat may injure the collaterals causing reckless movement of Blood.
-Damp-Heat may disturb the Urinary Bladder’s ability to separate to clear from the turbid, causing cloudy urine.
Emotions: long-standing frustration, anger and irritability will stagnate Liver Qi. Over time, this will generate Heat and Fire that will disrupt the Qi transformation function of the Urinary Bladder.
Chronic urinary strangury, aging, constitutional vacuity, taxation fatigue, or excessive sexual activity deplete the Spleen and Kidneys. This may result in Spleen Qi sinking, decline in the Kidney Qi and failure to secure Essence, or Yin vacuity with empty Heat. Any of these pathologies may result in urinary strangury.
Main Organs Involved in Urinary Strangury (Lín Zhèng)
Identification of Repletion vs. Vacuity
Damp-Heat, Qi stagnation, urinary stones may be present
Sharp, burning pain common when voiding
Urine may be dark, turbid or red
Spleen Qi vacuity, Kidney Qi or Yin vacuity common
Slight burning or no pain when voiding; dribbling more common
Urine is light in color or clear
Differential Diagnosis of Similar Disorders
-Oliguria-anuria: Characterized by difficultly urinating with less than normal urine volume or no urination at all. By comparison, urinary strangury often (though not always) presents with pain when voiding and the daily volume of urine output is adequate.
-Hematuria: Blood in the urine is a common symptom for both hematuria and Blood strangury. However, pain during urination is absent with hematuria and is always present with Blood strangury.
-Turbid Urination: Both Turbid Urination and Cloudy strangury manifest a milky appearance of the urine. To differentiate, pain is often a major symptom of Cloudy strangury but is absent with Turbid Urination.

Clinical Tips for Treating Urinary Strangury
Use diaphoretics and tonics cautiously. In ancient Chinese medical documents, diaphoresis and tonification are contraindicated as treatment methods for urinary strangury. In the initial stage of urinary strangury, aversion to cold, fever and general body ache may be present. Because frequent urination and excessive Heat of urinary strangury can damage the Yin, using acrid and warm herbs to induce sweating and release the exterior will further damage the Yin and complicate the condition.
However, if urinary strangury is caused by exterior Wind-Heat or exterior Damp-Heat with manifestations of aversion to wind, fever, cough and sore throat, acrid and cool herbs to induce sweating and release the exterior may be used. Tonification is contraindicated for repletion urinary strangury. Tonification is appropriate and recommended for vacuity urinary strangury, including Spleen Qi vacuity, Spleen Qi sinking, and Kidneys failing to secure the Essence.
“Use the strategy of unblocking obstructions to promote elimination in unremitting draining syndromes.” Unremitting draining syndromes include intractable diarrhea, frequent urination and flooding and leaking syndrome caused by replete pathogenic influences. This treatment method is only applicable in repletion patterns, including repletion patterns of urinary strangury. By clearing Heat, draining Dampness, moving Qi and Blood and dissolving stones, replete pathogenic influences and the obstruction they cause in the urinary tract will be removed, thus freeing and promoting urination.
The most common cause of hematuria in men over the age of 50 is carcinoma of the bladder. Therefore, persistent hematuria should never be treated without a proper biomedical workup.
