Microsurgical Varicocelectomy
Why Choose Microsurgical Varicocelectomy?
Microsurgical varicocelectomy (subinguinal microsurgical varicocelectomy) is widely recognized as the most precise, most comprehensive, and most effective method for treating varicocele—with the lowest risk of complications or recurrence.
Unlike higher-level varicocelectomy techniques, the microsurgical approach targets smaller, more numerous, and anatomically complex veins located beneath the external inguinal ring. This allows for meticulous dissection and identification of all problematic veins while preserving surrounding arteries, lymphatic vessels, and the vas deferens.

Comparison of Varicocele Surgery Techniques
| Surgical Type | Microsurgical Subinguinal | High Retroperitoneal | Traditional Inguinal | Laparoscopic | Scrotal * |
|---|---|---|---|---|---|
| Incision Size | ~1–2 cm | ~5–10 cm | ~5 cm | 3 incisions (~0.5–1 cm each) | — |
| Surgery Time | ~1–1.5 hours | ~1.5 hours | ~40 mins | ~30 mins | — |
| Recurrence/Persistent Symptoms | 0.4% | 15–29% | 2.6–13% | 3–6% | — |
| Complications | Scrotal edema (0.44%), hematoma | Scrotal edema (5–10%), testicular atrophy | Scrotal edema (7.3%), epididymitis, wound issues | Scrotal edema (7–43%), arterial injury, infection | Testicular atrophy, hematoma, edema |
| Special Risks | — | Failure to ligate external veins | Pain from muscle incision, nerve damage | Organ injury, gas embolism, shoulder pain | — |
| Comments | Smallest scar, preserves arteries, lowest recurrence | Larger wound, high recurrence | Shorter surgery, slightly higher recurrence | Allows bilateral repair, preserves arteries | High complication rate; rarely performed |
*Note: Scrotal surgery is rarely performed due to high complication rates and limited supporting data.
Our Surgical Approach: Microsurgical Subinguinal Varicocelectomy
Anesthesia
Traditionally, varicocelectomy is performed under spinal or general anesthesia. At our clinic, we use dual-local anesthesia, allowing patients to remain awake and comfortable. You can even use your phone or headphones during the procedure.
Incision
Whether unilateral or bilateral, only one small incision (~1–2 cm) is made above the scrotum or at the lower pubic area.
Hospital Stay
No hospitalization required. Patients may return home on the same day.
Surgical Procedure
The procedure is performed in the supine position with local anesthesia. Using a surgical microscope, a small incision is made above the scrotum (Figure 1A). The surrounding tissue is separated, and the spermatic cord is isolated (Figure 1B). Dilated veins are carefully dissected and tied with fine microsutures, preserving arteries, nerves, and lymphatic vessels (Figure 1C). No electrocautery is used to prevent thermal damage. The incision is closed with fine sutures (Figure 1D).

Key Benefits at Our Clinic
- Dual-local anesthesia
- Single small incision
- No hospitalization
- No electrocautery—minimal tissue damage
- Microsurgical precision—highest safety
- Reduced risk of complications such as hematoma, chronic pain, infection, or testicular atrophy
Same surgical principles are applied to other procedures including:
- Microsurgical circumcision
- Hernia repair
- Penile vein ligation
- Penile curvature correction
- Penile/testicular prosthesis implantation
- Vasectomy
- Dorsal nerve block surgery
Postoperative Outcomes
- Significant reduction or disappearance of visible/palpable scrotal veins
- Marked improvement in sperm count and motility for patients with poor semen parameters
- Pain relief in 48–90% of patients, especially those with more severe symptoms
- Possibility of sperm presence post-op in patients with azoospermia
- Sperm retrieval success rate increases 2.65x in patients with non-obstructive azoospermia
- Partners’ pregnancy rate increases by 2.39–4.15x post-treatment for oligospermia or idiopathic infertility
- No benefit in subclinical varicocele cases regarding pregnancy outcomes
- Testosterone levels can increase by an average of 34.3 ng/dL, improving hypogonadism symptoms
- May enhance erectile function in patients with ED
- May help delay ejaculation in patients with premature ejaculation
Conclusion
Microsurgical varicocelectomy offers the most effective and safe treatment for varicocele. With low recurrence, minimal incision, and high patient satisfaction, it’s the preferred method among urologists worldwide.
Always consult a specialized urologist to determine the best approach for your condition.
