Study Notes
Varicocele
- Dilated, tortuous veins in the pampiniform plexus, a common cause of male infertility.
- Primarily affects the left testicle due to anatomical differences in the testicular vein.
- Left testicular vein is longer, enters the left renal vein at a 90-degree angle, and is susceptible to compression by the sigmoid colon or the left adrenal vein.
- Varicocele disrupts the countercurrent mechanism, leading to increased testicular temperature and impaired spermatogenesis.
- Symptoms can include infertility, dull scrotal pain, and a palpable "bag of worms" sensation.
- Treatment is typically only required for symptomatic cases, and involves embolization or surgical ligation of the gonadal veins.
Congenital Hydrocele
- Occurs when the processus vaginalis, a peritoneal extension, remains open, allowing peritoneal fluid to enter the scrotum.
- A hernial sac may also be present.
- Treatment involves a herniotomy performed around 2-3 years of age.
Hydrocele of Cord
- Characterized by swelling along the spermatic cord.
- Treatment involves excision if symptomatic.
Spermatocele vs. Epididymal Cyst
- Spermatocele: Unilocular, located in the epididymal head, contains sperm, and fluid appears pale yellow.
- Epididymal Cyst: Multilocular, involves cystic degeneration of the epididymis, contains clear fluid that transilluminates, and lacks sperm.
- Both are treated by excision if symptomatic.
Scrotal Sebaceous Cysts
- Result from blocked hair follicle ducts in the scrotum.
- Do not pose an increased risk of cancer and are typically managed by excision.
Testicular Torsion
- Occurs when the spermatic cord twists, compromising blood supply to the testicle.
- Predisposing factors include a high attachment of the tunica vaginalis ("bell clapper testis"), testicular inversion, undescended testis, torsion of a cyst of Morgagni (associated with the "blue dot sign"), and rare cases of the testis separating from the epididymis.
- Presents with acute onset of severe scrotal pain and swelling.
- Differentiated from epididymo-orchitis by Prehn's sign (relief of pain with elevation of the testicle) and Deming's sign (the side of torsion is higher than the other).
- Diagnosis is clinical but supported by Doppler ultrasound, which demonstrates absent blood flow in the testicle.
- Management involves immediate surgical exploration and either de-rotation with orchidopexy (viable testis) or orchidectomy (necrotic testis), and prophylactic contralateral orchidopexy.
Testicular Disorders: Part 1
- Focuses on issues related to undescended testicles, cryptorchidism, and Fournier's Gangrene.
Undescended Testis
- The testicle fails to descend normally into the scrotum due to various factors.
- The descent typically begins in the third month of gestation, proceeding through the iliac fossa, inguinal canal, and finally into the scrotum by the ninth month.
- The process involves the pull of the gubernaculum, hormonal influences, and differential growth of the abdominal wall.
- Complications of an undescended testis include trauma, epididymo-orchitis, sterility, torsion, indirect inguinal hernia, and seminoma.
- The condition is usually identified by mothers, and the absence of scrotal rugosities (skin texture) suggests an undescended testis.
- Management depends on the age and location of the undescended testis, and includes conservative options, ideally followed by surgical correction between 6-12 months of age.
Cryptorchidism
- Both testicles are undescended.
- Treatment involves hormonal therapy and surgical exploration.
Orchidopexy
- Surgical procedure to fix an undescended or ectopic testicle in the scrotum, usually done between 6-12 months of age.
- Various techniques include Fowler-Stephens (two-stage procedure), Keetley-Torek, and Silbaar (most successful).
- If the testicle is necrotic or rudimentary, an orchidectomy is performed.
Ectopic Testis
- Occurs when a testis descends abnormally, often located in the superficial inguinal pouch.
- Treated by orchidopexy to bring the testicle into the scrotum.
Retractile Testis
- A normal variant where the testis can retract into the inguinal canal but can be manually repositioned into the scrotum.
- No treatment is required unless the testis consistently stays retracted.
Epididymo-orchitis
- Infection of both the epididymis and testicle.
- Common causative organisms include Chlamydia (< 40 years) and E. coli (> 40 years).
- Presents with acute scrotal pain, swelling, and fever.
- Distinguished from testicular torsion by the presence of relief with scrotal elevation (Prehn's sign).
- Management involves antibiotics, scrotal support, and pain relief.
Hydrocele
- Accumulation of fluid within the tunica vaginalis surrounding the testicle.
- Vaginal hydrocele: The most common type, occurs when there is either decreased fluid absorption (primary) or increased fluid secretion (secondary).
- Infantile hydrocele: Presents as inguino-scrotal swelling, often resolves spontaneously by the age of 1 year.
- Treatment: Small hydroceles may be treated with Lord's plication; larger ones may require Jaboulay's procedure.
- Infantile hydroceles are typically treated by excision of the excess sac and eversion of the sac if they don't spontaneously resolve.
Testicular Tumors
- Primarily involve germ cell tumors, accounting for 95% of cases, with seminomas being the most common overall.
- Non-seminomatous germ cell tumors include choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumor (most common in children).
- Sex cord/stromal tumors are less frequent, accounting for 5% of cases, and include Leydig cell and Sertoli cell tumors.
- Lymphoma is most common in elderly patients, with a tendency for bilateral testicular involvement (10-15%).
-
Clinical features:
- Typical: Painless testicular mass (most common), abdominal lumps (para-aortic lymph nodes).
- Atypical: Cannonball lung metastases (most common site of distant metastases), masculinization/precocious puberty/gynecomastia (Leydig cell tumors), feminization/gynecomastia (Sertoli cell tumors), Hurricane tumor (aggressive choriocarcinoma with a poor prognosis).
- Work-up: Ultrasound of the scrotum (to confirm the presence of a mass), tumor markers (AFP, b-hCG, LDH), histopathology (for confirmation), and PET-CT (for staging).
-
Staging:
- Based on TNM-S (tumor, node, metastasis, stage) system.
-
pTNM-S Staging:
-
T Stage:
- pT1: Limited to the testis and epididymis without vessel invasion.
- pT2: Limited to the testis and epididymis with vessel invasion or involving the tunica vaginalis.
- pT3: Involves the spermatic cord, with or without vessel invasion.
- pT4: Invades the scrotum with or without vascular invasion.
-
N Stage:
- N0: No regional lymph node metastases.
- N1: Lymph node mass ≤ 2 cm and up to 5 positive lymph nodes.
- N2: Lymph node mass 2-5 cm and more than 5 positive lymph nodes.
- N3: Lymph node mass > 5 cm.
-
M Stage:
- M0: No evidence of metastasis.
- M1: Metastasis, either to lungs/non-regional lymph nodes (A) or other sites (B).
-
S Stage:
- Based on tumor marker levels (LDH, HCG, AFP) measured 7-10 days after orchiectomy.
-
T Stage:
Management of Testicular Tumors
-
Seminomatous Tumors:
- Typically occur in the 2nd-3rd decades of life.
- Generally have a better prognosis.
-
Stages:
- Stage I: Confined to the testicle, treated with carboplatin and radiation therapy (inverted Y field).
- Stage II: Spread to para-aortic lymph nodes, treated with BEP chemotherapy (bleomycin, etoposide, cisplatin).
- Residual Disease: May require retroperitoneal lymph node dissection (RPLND) or radiation therapy.
-
Non-seminomatous Tumors:
- More aggressive and require more extensive treatment regimens.
- Usually involve chemotherapy and sometimes surgery.
-
Surgical Approach:
- Chevassu's maneuver: A technique to safely remove the testicle.
