Retroperitoneal lymph node dissection (RPLND) is surgery often used
to treat
testicular cancer. It is done to remove
lymph nodes in the lower back and pelvis that may be
cancerous.
During the early phases of stage I nonseminoma testicular cancer, it
can be very difficult to tell whether these lymph nodes are cancerous without
surgically removing them first. For this reason, RPLND may be performed even
though there is no sign that the cancer has spread (metastasized) beyond the
testes.
For many men, the greatest risk associated with RPLND involves
potential sexual side effects. In addition to the risks related to any major
surgery, RPLND also may lead to a condition known as retrograde ejaculation as
a result of nerve damage caused by the surgery. In retrograde ejaculation, the
semen flows from the prostate gland into the bladder rather than through the
penis and outside the body, resulting in infertility. Men who suffer from
retrograde ejaculation typically do not have erection problems or difficulty
enjoying sex.
An increasing number of RPLNDs are done using
laparoscopic surgery. Laparoscopy is a surgical
technique in which a lighted viewing instrument (laparoscope) and other
surgical instruments are inserted into the lower abdomen through small
incisions, usually made below the navel. Though not yet commonly available,
laparoscopic RPLND is much less invasive and carries less risk than standard
RPLND surgery.
Laparoscopic and other "nerve-sparing" techniques now used in many
RPLND surgeries have greatly lowered the risk of retrograde ejaculation.
Studies show that 95% of men who have nerve-sparing RPLND have normal
ejaculation after surgery.1
Nerve-sparing surgery is not possible for all men who have RPLND
surgery.
