Retroperitoneal lymph node dissection (RPLND) is a
surgical procedure to remove abdominal
lymph nodes. It is used to treat
testicular cancer
Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. Symptoms may include a lump in the testicle, or swelling or pain in the scrotum. Treatment may result in infertility.

, as well as to help establish the exact
stage and type of the cancer.
Indications
Testicular cancer
metastasizes in a predictable pattern, and lymph nodes in the
retroperitoneum are typically the first place it lands.
By examining the removed lymphatic tissue, a
pathologist can determine whether the disease has spread. If no malignant tissue is found, the cancer can be labeled Stage I, limited to the
testicle.
The procedure is common in the treatment of Stage I and II
non-seminomatous germ cell tumors.

is generally preferred to the invasive RPLND procedure.
Whether RPLND is needed after
orchiectomy depends on the type of tumor and its stage. RPLND may be performed to remove tumor remnants that persist after chemotherapy, because these remnants might otherwise spread and become resistant to the chemotherapy agents previously used.
Chemotherapy may be administered before RPLND and, if successful, may render surgery unnecessary. However, if the cancer does recur, surgery is much more difficult in a patient previously treated with chemotherapy.
Procedure
RPLND is usually performed using an incision that extends from the
sternum to several inches below the
navel. A less invasive procedure (L-RPLND) can be performed
laparoscopically, but this is more costly and time-consuming, and requires specialized equipment that not every hospital has. Additionally, it is unclear whether L-RPLND is as effective as the standard, open procedure.
Complications
Potential complications of RPLND include damage to the
sympathetic nerves

retrograde ejaculation
Retrograde ejaculation occurs when semen which would be ejaculated via the urethra is redirected to the urinary bladder. Normally, the sphincter of the bladder contracts before ejaculation, sealing the bladder which besides inhibiting the relea ...

Contrary to popular belief,
erectile function is not compromised by RPLND because the nerves responsible for erection are located elsewhere.
