Inguinal Radical Orchiectomy: Step-by-Step Technique
Inguinal radical orchiectomy with division of the spermatic cord at the internal inguinal ring is the gold standard initial intervention for suspected testicular cancer, and a scrotal approach must be avoided due to higher local recurrence rates. 1
Pre-Operative Considerations
Serum Tumor Markers
- Draw serum α-fetoprotein (AFP), β-hCG, and lactate dehydrogenase (LDH) before surgery to support diagnosis and establish baseline for post-operative monitoring 1
- Consider obtaining cord blood sample at time of surgery for tumor marker analysis 2
Fertility Preservation
- Offer semen cryopreservation ideally before orchiectomy, as sperm abnormalities and Leydig cell dysfunction are frequently present even before surgery 1
- This maximizes chances of future fertilization 1
Testicular Prosthesis Discussion
- Discuss prosthesis insertion at time of orchiectomy with the patient, as it decreases psychological effects of castration and does not delay adjuvant treatment 2
Imaging Confirmation
- High-frequency (>10 MHz) testicular ultrasound should confirm intratesticular mass location, size, multifocal disease, and contralateral testis characteristics 1
Surgical Technique
Incision and Approach
- Make an inguinal incision overlying the external inguinal ring, extending through skin and subcutaneous tissue 3
- Incise the external oblique aponeurosis to expose the inguinal canal 3
- The standard approach requires opening the inguinal canal and dividing the spermatic cord at the internal inguinal ring 1, 3
Cord Control and Mobilization
- Identify and isolate the spermatic cord at the level of the pubic tubercle before manipulating the testis 3
- Apply early vascular control by clamping the cord at the internal ring level to prevent tumor dissemination during manipulation 3
- Mobilize the cord and testis en bloc from the scrotum through the inguinal incision 3
Cord Division
- Divide the spermatic cord at the internal inguinal ring with high ligation 1, 3
- This ensures removal of the entire cord length and minimizes risk of residual disease 3
- Ligate the cord vessels securely to prevent hematoma formation 3
Specimen Removal
- Deliver the testis with attached cord and tunica vaginalis intact through the inguinal incision 3
- Avoid violating the tunica albuginea during removal 3
Hemostasis and Closure
- Achieve meticulous hemostasis in the inguinal canal and scrotal compartment 3
- Close the external oblique aponeurosis 3
- Close subcutaneous tissue and skin in layers 3
Alternative Technique: Subinguinal Approach
When to Consider
- The subinguinal approach divides the cord at the external inguinal ring, avoiding opening the inguinal canal 4, 5
- This technique may reduce risk of neuropathic injury to ilioinguinal nerve and incisional hernia 4
Oncological Considerations
- Current evidence shows no significant differences in oncological outcomes between subinguinal and high inguinal approaches for stage 1 and stage 2-4 cancers 5
- However, 12.5% of subinguinal cases showed unsatisfactory oncological control, with 78% due to cancer relapse and 16.5% due to spermatic cord invasion 5
- Given these concerns about residual proximal cord disease, the traditional high inguinal approach with cord division at the internal ring remains the standard of care 1, 3
Critical Technical Points
Avoid Scrotal Violation
- Never use a scrotal approach, as this is associated with higher local recurrence rates 1
- The inguinal approach provides proper oncological control 1
Early Vascular Control
- Clamp the cord early before extensive testicular manipulation to prevent hematogenous tumor spread 3
Complete Cord Excision
- Ensure division at the internal inguinal ring to remove all potentially involved cord tissue 1, 3
- Incomplete cord excision may leave residual disease 5
Special Circumstances
Testis-Sparing Surgery
- Only offer to well-informed patients with: single testicle, excellent compliance, single tumor <2 cm at lower pole, and normal preoperative endocrine function 1
- Take at least two additional biopsies from remaining testis to exclude germ cell neoplasia in situ (GCNIS) 1
- May also be considered for small/indeterminate masses with negative markers and normal contralateral testis 1
Contralateral Biopsy
- Offer to patients at high risk for contralateral GCNIS: testicular volume <12 ml and/or history of cryptorchidism 1
- Not indicated in patients >40 years without risk factors 1
Post-Operative Management
Tumor Marker Follow-Up
- Repeat serum tumor markers post-operatively considering half-life kinetics (AFP: 5-7 days, β-hCG: 24-36 hours) 1
- Delayed decline or rising levels provide staging and prognostic information 1
