Health Topic: Radical Prostatectomy

From Wikipedia

Prostatectomy (Greek, –prostates, “prostate”, combined with the suffix -ektomē, “excision”) is a medical term for the surgical removal of all or part of the prostate gland. This operation is done for benign conditions that cause urinary retention, as well as for prostate cancer and other cancers of the pelvis.

There are two main types of prostatectomies. A simple prostatectomy (also known as a subtotal prostatectomy) is when only part of the prostate is removed. Simple prostatectomies are typically only done for benign conditions.[1] A radical prostatectomy, the removal of the entire prostate gland, the seminal vesicles and the vas deferens, is performed for malignant cancer.[2]

There are multiple ways the operation can be done: as an open surgery (with a large incision through the lower abdomen), laparoscopically with the help of a robot (a type of minimally invasive surgery), through the urethra or through the perineum.

Other terms that can be used to describe a prostatectomy, include

  • Nerve-sparing: the blood vessels and nerves that promote penile erections are left behind in the body and not taken out with the prostate
  • Limited pelvic lymph node dissection: the lymph nodes surrounding and close to the prostate are taken out (typically the area defined by external iliac vein anteriorly, the obturator nerve posteriorly, the origin of the internal iliac artery proximally, Cooper’s ligament distally, the bladder medially and the pelvic side wall laterally[3]).
  • Extended pelvic lymph node dissection: lymph nodes farther away from the prostate are taken out also (typically the area defined in a limited PLND with the posterior boundary as the floor of the pelvis[3]).
