Microsurgical Excision of a Supernumerary Testis: A Novel Technique to Avoid Iatrogenic Injury to the Adjacent Testis.

Overview

OBJECTIVE: To describe a novel microsurgical technique for safely removing a supernumerary testis (SNT) without causing iatrogenic injury to the adjacent, normal testis. METHODS: In this report, we discuss the evaluation of a patient with chronic scrotal pain found to have a supernumerary testis (SNT), as well as a novel microsurgical approach for safely removing this testis. To avoid any iatrogenic injury to the adjacent testis, we used an operating microscope to visualize the cord structures of both testes and carefully remove the smaller, atrophic, supernumerary testis. RESULTS: The surgery was successfully completed without any intraoperative or postoperative complications. Total operative time was 2 hours. While the patient had not yet attempted to conceive at the time of follow-up, given our careful dissection, we expect him to have normal testicular function and fertility in the future. CONCLUSION: This case demonstrates a novel microsurgical approach to excising a supernumerary testis that avoids injury to the blood supply, epididymis and vas deferens associated with the normal testis.
