Prostatic hyperplasia is equivalent to Jing-癃 in Chinese medicine, which can occur due to not only kidney yin deficiency, but also due to damp-heat infiltration (dampness and heat invading the intestines, bladder, pubic area and lower limbs), spleen and kidney qi deficiency, qi stagnation and blood stasis (blood stasis due to the lack of qi), and kidney yang insufficiency (lack of yang qi in the kidneys). The main symptoms of seminal retention of urine are progressive frequent urination, noticeable at night with difficulty in urination and thinning of the urine line. Rectal examination of the prostate gland shows varying degrees of enlargement with clear margins, smooth surface, shallow or disappearing central sulcus, and no obvious pressure pain. Kidney-Yin deficiency type of seminal urine retention is often accompanied by scanty and reddish urine, lumbar and knee soreness (a feeling of soreness and weakness in the lumbar and knee regions), and five heart-heat (heat in the hearts of the hands and feet, and self-awareness of the heart and chest being hot and irritable). Dampness-heat-infiltration type of seminal urine retention is often accompanied by frequent yellowish red urine, burning or astringent pain in the urethra, yellowish greasy moss, and slippery pulse. Spleen and kidney qi deficiency type of seminal urine retention is often accompanied by fatigue (mental exhaustion and physical weakness) and lack of appetite. Qi stagnation and blood stasis type of seminal urine retention is often accompanied by fullness of pain in the abdomen and hematuria, dark tongue or petechiae.
