Testicular & Inguinoscrotal Examination

You are FY2 in the department of Urology. Miss Rachel Smith a 3rd-year medical student has asked you to teach her Inguinoscrotal Examination.

Testicular or Inguinoscrotal Examination

Performing an inguinoscrotal examination on a patient with a testicular lump involves assessing the groin and scrotal areas for any signs of swelling, inflammation, or lumps that may be associated with the lump in the testicle. Here are the steps involved in performing an inguinoscrotal examination:

  1. Preparation: Explain the procedure to the patient and obtain their consent. Provide them with a gown or sheet to cover their lower body, and ask them to lie down comfortably on the examination table.

  2. Inspection: Begin by visually inspecting the groin and scrotal areas for any signs of swelling, redness, or discoloration. Look for any lumps or bulges in the groin area, as well as any skin changes, such as rashes or lesions.

  3. Palpation: Next, palpate the groin area to check for any enlarged lymph nodes. Start at the top of the groin and work your way down towards the testicle, feeling for any lumps or nodules. Pay attention to any tenderness or pain the patient may experience.

  4. Examination of the inguinal canal: Use your fingers to gently probe the inguinal canal to assess for any inguinal hernias or masses. The patient should be asked to cough or strain, as this can help to detect any hernias.

  5. Examination of the scrotum: Proceed to examine the scrotum by gently palpating the testicles, epididymis, and spermatic cord. Compare the size, shape, and consistency of the affected and unaffected testicles. Check for any signs of tenderness or pain.

  6. Transillumination: If the lump is still unclear, transillumination can be performed. Darken the room and place a strong light source behind the scrotum. Check for any areas that appear darker or have an uneven glow.

  7. Follow-up: Depending on the findings of the examination, further diagnostic tests, such as an ultrasound or biopsy, may be recommended. The patient should be advised to follow-up with their healthcare provider for further evaluation and management.

It is important to note that any testicular lump should be taken seriously and evaluated promptly by a healthcare professional.

Prehn's test and its importance

Prehn's test is a physical examination maneuver that is used to differentiate between epididymitis/orchitis and testicular torsion, rather than a hydrocele. The test is typically performed with the patient standing, and involves lifting the affected testicle upwards while supporting the scrotum. The examiner then compares the size and tenderness of the testicle with the scrotum lifted and with the scrotum not lifted. If the pain or swelling is relieved with lifting the scrotum, it suggests epididymitis/orchitis. If the pain or swelling persists or worsens with lifting the scrotum, it suggests testicular torsion.

The significance of Prehn's test in differentiating between epididymitis/orchitis and testicular torsion is that it is a simple and quick test that can help guide urgent management. Testicular torsion is a surgical emergency that requires prompt intervention to save the testicle and preserve its function, while epididymitis/orchitis can often be treated with antibiotics and pain management. Therefore, the ability to quickly and accurately differentiate between the two conditions is critical for optimal patient outcomes.

The test can be useful in making a preliminary diagnosis and determining the appropriate management plan. However, it is important to note that Prehn's test is not always definitive, and further diagnostic tests, such as ultrasonography or surgical exploration, may be necessary to confirm the diagnosis.

Describing your findings

As a doctor, you may encounter patients who present with testicular lumps during routine physical examinations or when they notice a lump on their own. It is important to conduct a thorough testicular examination and properly describe any testicular lump that you find.

To describe a testicular lump, you should note the following characteristics:

  1. Location: Identify where the lump is located within the testicle. Testicular lumps can be located on the surface of the testicle or deeper within the tissue.

  2. Size: Measure the size of the lump in centimeters or millimeters. You can use calipers to accurately measure the size of the lump.

  3. Shape: Determine the shape of the lump. Testicular lumps can be round, oval, irregular, or lobulated.

  4. Consistency: Determine if the lump is hard, firm, soft, or fluid-filled. This information can help differentiate between different types of testicular lumps.

  5. Tenderness: Assess if the lump is tender or painful when touched.

  6. Mobility: Determine if the lump is movable or fixed within the testicle.

Different types of testicular lumps and their clinical characteristics

Here are several types of testicular lumps that can be differentiated clinically based on their characteristics. The following are some of the most common types of testicular lumps:

  1. Hydrocele: A hydrocele is a fluid-filled sac that forms around the testicle. Hydroceles are usually painless and can be easily diagnosed on physical examination. They are typically soft and can be transilluminated, meaning that light can be seen through the lump when a light source is placed against the skin.

  2. Varicocele: A varicocele is an enlargement of the veins within the scrotum, similar to varicose veins in the legs. Varicoceles are typically painless and can be identified by feeling a "bag of worms" on physical examination.

  3. Spermatocele: A spermatocele is a cyst that forms within the epididymis, the tube that carries sperm from the testicle. Spermatoceles are typically painless and can be differentiated from testicular cancer because they are separate from the testicle itself.

  4. Testicular torsion: Testicular torsion is a medical emergency that occurs when the testicle twists on its blood supply, causing severe pain and swelling. Testicular torsion requires immediate surgical intervention to prevent loss of the testicle.

  5. Testicular cancer: Testicular cancer is a malignant tumor that forms in the testicle. Testicular cancer typically presents as a painless, hard lump on the testicle, and may be associated with swelling or enlargement of the testicle. Testicular cancer is usually diagnosed with a combination of physical examination, ultrasonography, and blood tests.

It is important to differentiate between these different types of testicular lumps because their management and prognosis can vary significantly. A thorough physical examination, along with diagnostic tests such as ultrasonography, can help differentiate between these different types of lumps and guide appropriate management.

What to do if a lump is found

After discovering a testicular lump, you should consider further testing and referral to a urologist or specialist. The following steps may be taken:

  1. Ultrasonography: A scrotal ultrasonography is a non-invasive diagnostic test that can help identify the characteristics of the testicular lump. The test can differentiate between solid masses, cysts, or other fluid-filled structures within the testicle.

  2. Blood tests: A blood test can be used to measure tumor markers, such as alpha-fetoprotein (AFP), human chorionic gonadotropin (HCG), and lactate dehydrogenase (LDH), which can help identify the presence of testicular cancer.

  3. Biopsy: A biopsy may be needed if the testicular lump is suspicious for cancer. A biopsy involves removing a small piece of tissue from the lump and analyzing it under a microscope.

  4. Referral: Referral to a urologist or specialist may be necessary for further evaluation and management.

It is important to communicate with your patient about the testicular lump and provide reassurance that most testicular lumps are benign. However, prompt evaluation and proper management are essential for identifying and treating potential testicular cancer.

Testicular emergencies

There are several testicular emergencies that require urgent medical attention. These conditions include testicular torsion, testicular trauma, and testicular rupture. The following is a brief overview of these conditions and their management:

  1. Testicular torsion: Testicular torsion is a medical emergency that occurs when the testicle twists on its blood supply, causing severe pain and swelling. Immediate surgical intervention is required to untwist the testicle and restore blood flow. If left untreated, testicular torsion can result in loss of the testicle and infertility.

  2. Testicular trauma: Testicular trauma can occur from direct blows to the testicle, causing pain, swelling, and bruising. Management of testicular trauma depends on the severity of the injury. Mild injuries may require rest and pain management, while more severe injuries may require surgery to repair any damage to the testicle or surrounding structures.

  3. Testicular rupture: Testicular rupture occurs when the testicle is ruptured or torn, typically from blunt force trauma. Testicular rupture is a medical emergency that requires immediate surgical intervention to repair the damaged testicle. If left untreated, testicular rupture can result in loss of the testicle and infertility.

It is important to seek medical attention immediately if you or someone you know experiences any of these testicular emergencies. Prompt management is essential for preserving testicular function and preventing long-term complications.

Testicular torsion, its diagnosis and management

Testicular torsion is a medical emergency that requires urgent diagnosis and management to preserve testicular function. The following is an overview of how testicular torsion is diagnosed and managed:

Diagnosis:

  1. Physical examination: The first step in diagnosing testicular torsion is a thorough physical examination of the scrotum, testicles, and groin area. The testicle is typically swollen and tender to touch, and there may be an absence of the cremasteric reflex (the reflex that causes the testicle to retract in response to touch or cold temperature).

  2. Imaging studies: Imaging studies such as ultrasonography can be used to confirm the diagnosis of testicular torsion by visualizing the testicle and the blood flow to it.

Management:

  1. Surgical intervention: Surgical intervention is required to untwist the testicle and restore blood flow. This is typically done through a surgical procedure called an orchidopexy, which involves detorsion of the testicle and fixation of the testicle to the scrotum to prevent future torsion.

  2. Pain management: Pain management is an important part of the management of testicular torsion. Analgesic medications such as opioids or non-steroidal anti-inflammatory drugs (NSAIDs) may be used to manage pain.

  3. Follow-up: Follow-up care is important to monitor for complications such as testicular atrophy, which can occur if blood flow is not restored quickly enough. Follow-up care may include serial ultrasonography to monitor blood flow to the testicle and ensure that the testicle is healing properly.

In summary, testicular torsion is a surgical emergency that requires urgent diagnosis and management. Surgical intervention is necessary to restore blood flow to the affected testicle, and prompt management is essential for preserving testicular function and preventing long-term complications.
