Use of subinguinal incision for microsurgical testicular biopsy during varicocelectomy in men with nonobstructive azoospermia

Objective

To describe a subinguinal technique of microsurgical testicular biopsy performed during subinguinal varicocelectomy in men with nonobstructive azoospermia.

Design

Prospective clinical study.

Setting

Andrology laboratory at tertiary care hospital. Male infertility section, department of urology, at tertiary care hospital.

Patient(s)

Ten azoospermic men with clinical varicocele.

Intervention(s)

Subinguinal microsurgical testicular biopsy and microsurgical varicocele repair.

Main Outcome Measure(s)

Safety, feasibility, and effectiveness of subinguinal testicular biopsy during varicocele repair.

Result(s)

All testes were easily delivered through the subinguinal incision, and testicular biopsies were successfully performed under microscopic view. After a median follow-up of 9 months, none of the patients had any discomfort, pain, or presented with testicular atrophy. No intraoperative or postoperative complications were observed. There was no incidence of wound infection or scrotal hematoma.

Conclusion(s)

The subinguinal approach is a safe and effective option for testicular biopsy during varicocele repair in men with nonobstructive azoospermia. This technique may be an attractive alternative to traditional biopsy because it obviates scrotal violation.
