Prostate cancer is the greatest in ...

Prostate cancer is the greatest in quantity common type of cancer diagnosed in men accounting for 11% of cancer deaths. It is the inferior leading cause of cancer death among men in the United States, after lung cancer. (1) Although there are a variety of treatment modalities available, surgical excision of the prostate gland remains the course of choice for many men with localized disease. Traditionally, a major exhibit abdominal procedure (ie, radical prostatectomy) was the simply option, and it required an stretch outed hospital stay and recovery time. Patients frequently required blood transfusions and were at risk for the two incisional infection and secondary infection from the long-term indwelling Foley catheter. Impotence and urinary incontinence were the brace most common side effects of the surgery (2) Surgical techniques have evolv (eg nerve-sparing surgery in the 1980s) moreover the development of laparoscopic radical prostatectomy (LRP) has been common of the most significant changes in surgical treatment of this disease. As with any just discovered procedure, training is required for surgeon and perioperative nursing staff members onward an ongoing basis as modifications continue to be made. Clinical issues need to be monitored continuously, and, to date, the management demonstrates good results and higher patient satisfaction than traditional lay open surgery.

ANATOMY AND PHYSIOLOGY

The prostate gland, which is part of the male reproductive anatomy, is located below the bladder and encloses the urethra (Figure 1). The fore-rank wall of the rectum lies just beneath the prostate. A normal gland is approximately 4 cm in diameter and weighs roughly 20 g which is comparable to a small walnut. It is made up of fibromuscular tissue that contains alveoli and tubular canals (3)

[FIGURE 1 OMITTED]

The prostate is compos of right and left sides and lobes. Conical in shape, the tip farthest from the bladder is called the apex and the wider portion is the base. The base adheres to the bladder and the apex adheres to the fascia and muscle tissue forming the urogenital diaphragm. The prostate gland is enclos in a prostatic capsule and encompassed by extraperitoneal connective tissue. Denonvilliers' fascia comprises pair layers of endopelvic fascia, which separates the prostate from the rectum (4) If the capsule has been penetrated at disease, there is a greater likelihood that the disease has or will spread. (5)

The gland is divided into three bands (ie, peripheral, central, transition). The largest is the peripheral girdle which makes up two-thirds of the prostate gland. The peripheral region encompasses the anterior and posterior portions of the prostate, from apex to base. The central baldric is the second largest clime It is cone shaped and incorporates principally of the base of the prostate. The transition climate the smallest zone, is the location where benign prostate hypertrophy (BPH) occurs; therefore, it frequently is called the BPH cincture (6)

Neurovascular fibers or packages are located on each side of the prostate. These fibers contain the vital current and nerve supply critical to erectile function; therefore, maintaining their integrity during surgery when possible, is important. (7) The dorsal venous composite is contained in the retroperitoneal connective tissue that shields the prostate. (8) The prostatic pedicles are groupings of connective tissue establish on either side of the vas deferen and seminal vesicle. These pedicles help stabilize the prostate.

The bladder is located just above the prostate and posterior to the seminal vesicles, vas deferen ureter and rectum (9) The urethra leads from the bladder end the prostate, past the urinary sphincter, and gone out the penis. The urinary sphincter is a form into groups of circular muscle fibers located just below the prostate that obstruct leakage of urine during physical activity and coughing. A los of mastery of this sphincter leads to incontinence. (10)

There are pair was deferens in the male anatomy located forward the lateral sides of the prostate gland. The vas deferen are tubelike textures that allow sperm to travel from the testicle to the urethra. In the prostate gland, the vas deferen continue as the ejaculatory conduits which empty sperm into the urethra. The testicles bring the male hormone testosterone and make semen (11) During ejaculation, the prostate uses rhythmic contractual emotions to secrete prostatic fluid into the urethra. This fluid is an alkaline pH milky, thin substance that helps harbor the sperm as it travels in the acidic female reproductive tract. (12)

Enlargement of the prostate causes a narrowing of the urinary passageway. This narrowing makes it increasingly difficult for the male to maintain a constant sweep along of urine. Clinical symptoms include

* urinary frequency

* hesitancy,

* inactive urinary stream,

* retention,

* nocturia, and

* dysuria. (13)

PROSTATE CANCER

Adenocarcinoma of the prostate is the principally common form of cancer in American males. The American Cancer Society estimated that approximately 198000 men were newly diagnosed with prostate cancer in 2001 More than 31000 men were likely to die from the disease in the same year. (14) During their lifetime, united in six men will be diagnosed with prostate cancer, however only one in 30 is likely to die of the disease. The incidence is higher in African American men than in Caucasian or Asian males. (15)
