This blog entry will briefly discuss important considerations for men undergoing orchiectomy for testis cancer.
RationaleThis surgery involves removing the testicle and spermatic cord where it exits the body to identify and likely treat the majority of cancers localized to the testis. As a male fetus develops, the testes develop near the fetal kidneys. As the fetus grows, the testicles separate from the kidneys and, at about the eighth month of pregnancy, the testicles exit the body wall to rest in the scrotum (this is why premature infants have a higher likelihood of having undescended testicles). Therefore the blood supply, lymphatic drainage and nerves to the testicle originate near the kidney on that side. Once these structures exit the body through the internal inguinal ring they fuse with muscles of the body wall to form the spermatic cord. To correctly stage and prevent any cancer from spreading, the spermatic cord must be taken as high toward or inside the body as possible -- hence the incision in the groin rather than the scrotum.
For men whose cancer has spread from the testicle and who have metastatic testis cancer (elsewhere in the body) or in the lymph nodes of the retroperitoneum, radical orchiectomy is an important first step in the diagnosis and management of disease. Knowing the type of cancer may help guide chemotherapy or radiation treatments.

Once the testicle and spermatic cord are entirely free from the inguinal canal, the testicle can be removed. The spermatic cord should be ligated in two packets - one containing the gonadal artery and one containing the vas deferens (sperm duct) and its associated artery. A large, non-absorbable suture should also be tied to the distal spermatic cord to facilitate easy identification in the case that a retroperitoneal lymph node dissection needs to be performed in the future. Care should be taken to close the external oblique fascia to the level of the external ring to prevent future hernia.
ComplicationsThe biggest risk of a radical orchiectomy is hematoma (or bleeding into the scrotum). It is very common for the scrotum to be bruised, swollen and tender for 2-4 weeks after surgery. However, a large, purple-appearing scrotum can indicate a hematoma. Hematoma can be prevented with a compressive dressing, tight-fitting undergarments and/or ice packs.
Ilioinguinal nerve injury can occur if the nerve is damaged during dissection of the spermatic cord. This is more common in men who underwent prior inguinal surgery (usually for an undescended testicle or hernia repair) and can occur during dissection or be inadvertently trapped in the closure of the external oblique fascia. The deficit is often decreased sensation to the medial thigh, scrotum or base of the penis. It is often transient, but can take several weeks or months to improve.
Inguinal hernia can occur if the external oblique fascia is not closed properly or if the closure breaks down. It is important to minimize strenuous activities for 2-4 weeks to prevent development of a hernia.

Testicular ProsthesisProstheses should be offered to all men undergoing orchiectomy. Not all men want a prosthesis -- it is a personal decision. The prosthesis should be measured in the operating room with the patient asleep. The goal should be to match the remaining testicle in size taking into account a cancerous testicle can be larger or smaller than normal, and the scrotal skin will make a prosthesis look larger once implanted.
TESTIS-SPARING SURGERY (PARTIAL ORCHIECTOMY)
RationaleWhile radical orchiectomy remains the standard-of-care for the diagnosis and treatment of testis cancer, there are a couple of circumstances where testis-sparing surgery is advocated. The primary indications are in men with:
- bilateral testis cancers (either synchronous, at the same time; or metachronous, that develop some time after the first testicle is removed)
- the standard-of-care would be to remove both testicles under suspicion of cancer, however the implications regarding fertility and testosterone replacement are well-established
- small, palpable testis masses and normal serum tumor markers
- these men have a low, but significant risk of having a benign mass or non-germ cell cancer that does not require orchiectomy
- if a testis cancer is confirmed, a radical orchiectomy is completed
- small, non-palpable, ultrasound detected testis mass with normal tumor markers
- approximately 80% likelihood of benign mass

ComplicationsThe complications are the same for radical orchiectomy and testis-sparing surgery. In addition, even if testis-sparing surgery is performed, surgery can result in infertility or hypogonadism if the internal blood supply to the testicle is harmed or if the tubules are disrupted.
SummaryRadical orchiectomy is the standard-of-care for men with suspicion of testis cancer and is therefore the most common operation done for testicular cancer. Testis-sparing surgery (or partial orchiectomy) is a novel approach suitable for some patients.
