Chronic epididymitis is a relatively common condition in urology and male clinics, mostly in young men, mainly manifested as long-term (3 months or more) chronic involvement pain in the scrotum, testicles or inguinal region, and examination of the epididymis which is obviously swollen and painful to the touch, or even the epididymis is swollen and resembles a hard mass that does not subside. Chronic epididymitis is divided into three categories: 1. chronic inflammatory epididymitis, which is the most common and most prevalent one in the clinic, refers to chronic painful discomfort of the epididymis with swelling, hard nodes and other inflammatory manifestations. 2.Obstructive chronic epididymitis refers to pain or discomfort caused by congenital, acquired or medical obstruction of the epididymis or vas deferens (such as obstruction of the vas deferens caused by congenital obstruction or scar formation after vasectomy). 3. Chronic epididymal pain is sometimes difficult to distinguish from chronic testicular pain, and it is difficult to find a clear cause. Those who have the above chronic epididymitis should actively go to the regular hospital male department or urology department for consultation, because chronic epididymitis can lead to epididymal obstruction in some people, especially when bilateral obstruction occurs at the same time, which can lead to azoospermia. The treatment of chronic epididymitis is roughly as follows: For patients with mild symptoms and short duration, early treatment such as antibiotics can be used. Local elevation of the scrotum, local hot compresses, hot water sitz baths (prohibited for those with fertility requirements) and physiotherapy can relieve symptoms. Attention is also paid to avoid triggering and aggravating factors such as excessive intercourse and prolonged sitting and riding. However, it is also necessary to have sex, preferably to ensure once every 3-5 days, to actively expel inflammatory fluid from the body and promote improvement. Antibiotics are the most commonly used clinical treatment drugs, but there is no clear treatment plan for chronic epididymitis. The effect of applying antibacterial drugs alone is not always ideal. If there is chronic prostatitis, it must be treated at the same time. In case of recurrent episodes of epididymitis originating from chronic prostatitis, those who are not cured or have recurrent episodes and have no fertility requirements may consider ligation of the vas deferens before treatment. If the local pain is severe and recurrent, affecting life and work, epididymectomy can be considered as the last resort to relieve the symptoms.
