Understanding Hydroceles: Causes, Symptoms, and Treatment Options for Adults

In this video, we're delving into the crucial details you need to know about hydroceles—a condition characterized by the accumulation of fluid in the scrotum, the sac of skin that holds your testicles. Most hydroceles develop without any apparent reason, are harmless, and can be left untreated. However, if necessary, a minor surgical procedure can effectively resolve the issue. Our focus here is on hydroceles in adults, covering their causes, symptoms, diagnostic tests, treatment options, and when you should consult a doctor about a lump on your testicle.

Before we dive into the specifics of hydroceles, let's briefly discuss what is considered normal anatomy. The scrotum is typically loose, soft, and fleshy, housing two testicles. You should be able to easily feel your testicles in the scrotum. A tube called the vas deferens carries sperm from each testicle to the penis. With this basic understanding of normal anatomy, let's explore what a hydrocele is.

A hydrocele is essentially a collection of fluid in the sac within your scrotum, adjacent to a testicle. It usually forms on one side but can sometimes develop on both testicles. The normal testicle is surrounded by a smooth, protective tissue sac that you typically can't feel. This sac produces a small amount of lubricating fluid to allow the testicle to move freely. Normally, excess fluid drains away into the veins in your scrotum. However, if the balance between fluid production and drainage is disrupted, fluid can accumulate, resulting in a hydrocele.

So, who is most susceptible to hydroceles? While hydroceles can occur in children, they are most common in adults, particularly men over the age of 40. In many cases, the exact cause of a hydrocele remains unknown.

What do hydroceles look and feel like? A hydrocele feels like a small, fluid-filled balloon within your scrotum. It has a smooth texture and is usually located in front of one of your testicles. Hydroceles can vary significantly in size, with very large hydroceles sometimes observed in elderly men who may have never sought medical attention for their swelling. Over time, the hydrocele may have gradually increased in size. Typically, hydroceles are painless, but large hydroceles can cause discomfort due to their size, making activities like walking or sexual intercourse uncomfortable.

A common question is whether you need any tests if you suspect you have a hydrocele. If you think you have a hydrocele, a doctor will examine your testicles. The doctor may also shine a light through your scrotum. If the hydrocele is large and the doctor cannot feel your testicle, the fluid may be drained using a needle and syringe. Once the fluid is removed, your testicles can be more easily examined. Sometimes, your clinician may recommend an ultrasound scan, also known as a jelly scan, to check your testicles and ensure there is no underlying cause for the hydrocele.

Now, let's discuss the treatment options available for hydroceles.

1. **Leaving it Alone**: In adults, if the hydrocele is asymptomatic, one option is to leave it untreated. You can use supportive wear, like a jock strap, to enhance comfort. If the hydrocele becomes larger or more troublesome, you can always opt for treatment later.

2. **Surgery**: Surgery may be recommended if your hydrocele is large or causing discomfort. The procedure involves making a small incision in the scrotum or lower abdomen to drain the fluid surrounding the testicle. The passage between the abdomen and scrotum is sealed off to prevent fluid reformation. This minor operation is typically performed as a day case, so it usually doesn't require an overnight hospital stay. While hydroceles can recur after surgery, this is uncommon.

3. **Fluid Drainage**: Fluid can be drained using a needle and syringe. However, the sac of the hydrocele often refills with fluid after a few months. Periodic drainage might be suitable if you are not fit for surgery or prefer not to undergo an operation. Keep in mind that this procedure carries risks, such as infection.

Remember, it's crucial to consult a doctor if you notice any lumps, swellings, or changes in your testicles. Regularly checking your testicles helps you understand what's normal for you.
