According to the theory of traditional Chinese medicine, there are some patterns of syndrome that lead to hydronephrosis.
1. Pattern of Kidney Yin Deficiency
2. Pattern of Spleen Deficiency
3. Pattern of Qi and Blood Stagnation
4. pattern of Qi due to damp-Heat

Integration of Chinese medicine and western medicine would be a good choice for this disease. When treating hydronephrosis, Chinese doctors will take everything into consideration, including the following conditons.
1. Causes in women
In women, common causes of hydronephrosis include:
pregnancy – during pregnancy the enlarged womb (uterus) can sometimes place pressure on the ureters
cancers that develop inside the urinary tract, such as bladder cancer or kidney cancer
cancers that develop inside the reproductive system, such as cervical cancer, ovarian cancer or cancer of the womb

2. Causes in men
In men, the two most common causes of hydronephrosis are:
non-cancerous swelling of the prostate gland (benign prostatic hyperplasia)
prostate cancer
Both conditions can place pressure on the ureters, which can block the flow of urine. The ureters are the tubes that run from your kidneys to your bladder.
