Hydrocele

Introduction Hydrocele refers to a small amount of liquid (2 to 3 ml) in the normal testicular sheath sac for smoothing and protecting the testes. If there is too much liquid, it is hydrocele. The concept of hydrocele should include hydrocephalus, hydrocele, hydrocele, and colitis.

Cause

(a) primary hydrocele

1. The reason is unknown. It may be caused by increased secretion of the sheath, decreased absorption, or due to undetected or healed testicular epididymitis.

2. The peritoneal sheath is not closed, and the fluid in the peritoneal cavity flows into the peritoneal sheath to form congenital hydrocele.

(two) secondary hydrocele

Testis, epididymal inflammation, tuberculosis, scrotal filariasis, testicular tumors, scrotal surgery, trauma can cause secondary hydrocele, which often contains white blood cells.

Light transmission test

Examination: testicular hydrocele and spermatic hydrocele are generally spherical or ovoid. Infant hydrocele is pear-shaped and tapers in the groin. Traffic hydrocele is spherical or pear-shaped, which can be reduced or disappeared when lying down. Sometimes the traffic tunnel is very small, and it can be slightly reduced in bed for a long time, so it is easy to be misdiagnosed as infantile hydrocephalus or hydrocele hydrocele.

The surface of the mass is smooth, elastic and cystic, and the tension is small. The spermatic hydrocele can touch the testicle below it, sometimes mistaken for three testes. Other types of hydrocele often fail to understand the testis and epididymis of the affected side. Except for traffic hydrocele, they cannot be repaid. The hydroponics test of the hydrocele was positive; if the wall of the sheath was thickened, the contents were turbid, and there was bleeding, it could also be opaque. Hemorrhoids, testicular tumors, scrotal hematoma light transmission test is negative, but children may also have light transmission. So you can't take the puncture.

Differential diagnosis

Differential diagnosis

1. Identification with inguinal hernia: The traffic hydrocele is extremely narrow in communication with the abdominal cavity. It can only pass through the liquid, can not pass through the intestine or the omentum, and the sputum can pass. Therefore, it has the following characteristics:

1 The neck of the capsule is thicker and the subcutaneous loop is enlarged.

2 The contents can be repaid or in the past, and there is a history of snoring.

3 Cough has a shock.

4The drum sound, no fluctuation, can touch the testicles, sometimes you can hear the bowel sounds.

5 light transmission test, is negative.

2. Identification with other diseases:

1 hydrocele: a history of trauma, scrotal skin often has ecchymosis. Its weight is also heavier than stagnant water.

2 testicular tumors: hard, not smooth and have a special heavy feeling, no tenderness. The epididymis can be touched behind the mass, and the light transmission test is negative.

3 sheath chyle: the characteristics of filariasis: thick legs, large inguinal lymph nodes, increased eosinophils in the blood, microfilaria in the night blood. The scrotal mass was negative for the light transmission test, and the microfilaria was found in the puncture fluid, and the liquid was chylostatic.

4 semen cyst: mostly located in the epididymis head, the puncture fluid is milky white, you can see the sperm.
