Prostatectomy
Encyclopedia
A prostatectomy is the surgical removal of all or part of the prostate gland. Abnormalities of the prostate, such as a tumour, or if the gland itself becomes enlarged for any reason, can restrict the normal flow of urine
Urine
Urine is a typically sterile liquid by-product of the body that is secreted by the kidneys through a process called urination and excreted through the urethra. Cellular metabolism generates numerous by-products, many rich in nitrogen, that require elimination from the bloodstream...

There are several forms of the operation:

Transurethral resection of the prostate (TURP)

A cystoscope [a resectoscope which has a 30 degree viewing angle, along with resectoscopy sheath & working element] is passed up the urethra to the prostate, where the surrounding prostate tissue is excised. This is a common operation for benign prostatic hyperplasia

 (BPH) and outcomes are excellent for a high percentage of these patients (80-90%).

Conventional (monopolar) TURP

The conventional TURP method in tissue removal utilizes a wire loop with electrical current flowing in one direction (thus monopolar) through the resectoscope to cut the tissue. A grounding ESU pad and irrigation by a nonconducting fluid is required to prevent this current from disturbing surrounding tissues. This fluid (usually glycine) can cause damage to surrounding tissue after prolonged exposure, resulting in TUR syndrome, so surgery time is limited.

Bipolar TURP

Bipolar TURP is a newer technique that uses bipolar current to remove the tissue. Bipolar TURP allows saline

 irrigation and eliminates the need for an ESU grounding pad thus preventing TUR syndrome and reducing other complications. As a result bipolar Turp is also not subject to the same surgical time constraints of conventional TURP.

Laser prostate surgery

Another surgical method utilizes laser energy to remove tissue. With laser prostate surgery a fiber optic cable pushed through the urethra is used to transmit lasers such as holmium

An adenoma is a benign tumor of glandular origin. Adenomas can grow from many organs including the colon, adrenal glands, pituitary gland, thyroid, prostate, etc. Although these growths are benign, over time they may progress to become malignant, at which point they are called adenocarcinomas...

. More recently the KTP laser has been supplanted by a higher power laser source based on a lithium triborate crystal, though it is still commonly referred to as a "Greenlight" or KTP procedure. The specific advantages of utilizing laser energy rather than a traditional electrosurgical TURP is a decrease in the relative bloodloss, elimination of the risk of TUR syndrome, the ability to treat larger glands, as well as treating patients who are actively being treated with anti-coagulation therapy for unrelated diagnoses.

Open prostatectomy

In an open prostatectomy the prostate is accessed through an incision that allows manual manipulation and open visualization through the incision. The most common types of open prostatectomy are radical retropubic prostatectomy (RRP) and radical perineal prostatectomy (RPP).

, and the prostate is removed, by going behind the pubic bone (retropubic).

 through which the prostate is removed. This procedure has become less common due to limited access to lymph nodes and difficulty in avoiding nerves.

Suprapubic transvesical prostatectomy

Another type of open prostatectomy is suprapubic transvesical prostatectomy (SPP) where an incision is made in the bladder. SPP remains a common surgical treatment for BPH in Africa but has largely been supplanted by TURP in the West for this application. SPP may be indicated for use with large patients and prostates because of the surgical time constraints associated with conventional TURP.

Laparoscopic radical prostatectomy

This is a laparoscopic procedure involving four small incisions made in the abdomen used to remove the entire prostate for treatment of prostate cancer.

Computer-assisted laparoscopic radical prostatectomy (CALP)

Computer-assisted instruments are inserted through several small abdominal incisions and controlled by a surgeon. Some use the term 'robotic' for short, in place of the term 'computer-assisted'. However, procedures performed with a computer-assisted device are performed by a surgeon, not a robot. The computer-assisted device gives the surgeon more dexterity and better vision, but no tactile feedback compared to conventional laparoscopy. When performed by a surgeon who is specifically trained and well experienced in CALP, there can be similar advantages over open prostatectomy, including smaller incisions, less pain, less bleeding, less risk of infection, faster healing time, and shorter hospital stay. The cost of this procedure is higher, whereas long-term functional and oncological superiority has yet to be established.

Sexual effects of prostatectomy

Surgical removal of the prostate risks an increased likelihood that patients will experience erectile dysfunction

. Nerve-sparing surgery reduces the risk that patients will experience erectile dysfunction. However, the experience and the skill of the nerve-sparing surgeon, as well as any surgeon are critical determinants of the likelihood of positive erectile function of the patient.

Remedies to post-operative sexual dysfunction

Very few surgeons will claim that patients return to the erectile experience they had prior to surgery. The rates of erectile recovery that surgeons often cite are qualified by the addition of Viagra to the recovery regimen.

Remedies to the problem of post-operative sexual dysfunction include:
  • Medications
  • Intraurethral suppositories
  • Penile injections
  • Vacuum devices
  • Penile implants
