What causes hydrocele?

For male friends, if they want to better prevent and reduce the harm caused by hydrocele, then we need to pay attention to understand the causes, such as external injuries, viral infections, and some systemic diseases may cause hydrocele.

A tumor:

The lesions and swellings in the testis, epididymis, tunica vaginalis, spermatic cord and other parts can invade the tunica vaginalis, causing increased secretion and exudation or blocking the lymphatic system, resulting in hydrocele. The incidence of hydrocele in testicular tumors is 2% to 5%.

2. Damage:

It is also a common cause of symptomatic hydrocele. It has been reported that 67% of patients develop hydrocele after renal transplantation, 35% after varicocele surgery, 0.9%-2.28% after hernia repair surgery, epididymisectomy, inguinal lymph node dissection, etc. can cause hydrocele due to stimulation of the spermatic cord and damage to the lymphatic vessels.

3. Infection:

The most common cause is acute or chronic epididymitis, orchitis, spermatic cord inflammation, and hydrocele caused by the invasion of tuberculosis, lb diplococcus, and various non-specific bacteria such as E. coli, Staphylococcus, and Streptococcus. Mumps virus infection can also cause it. Parasitic infections such as filariasis, which are prevalent in tropical regions, can also damage the lymphatic drainage of the hydrocele, spermatic cord, and scrotum, leading to hydrocele.

4. Certain systemic diseases:

Hydrocele can also occur if water and sodium retention, circulatory stagnation, lymphatic obstruction, etc. are caused by heart and kidney failure, liver disease, etc., and are often accompanied by systemic tissue edema or ascites. In addition, some benign lesions of the scrotum, such as testicular torsion, testicular appendage torsion, spermatic cord varicocele, etc., can also induce hydrocele. Secondary hydrocele has primary diseases, such as acute orchitis, epididymitis, spermatic cord inflammation, etc., which stimulate the increase of hydrocele exudate and cause hydrocele. Scrotal surgery damages lymphatic vessels, causing reflux obstruction, as well as high fever, heart failure, ascites, etc., which manifests as acute hydrocele; chronic secondary effusion is common in chronic orchitis, epididymitis, syphilis, tuberculosis, testicular tumors, etc., causing increased hydrocele secretion and accumulation of fluid. In addition, filariasis and schistosomiasis can also cause hydrocele. The fluid often contains white blood cells.
