Managing Benign Prostatic Hyperplasia - Article
ABSTRACT: Medical and surgical options for the treatment of benign prostatic hyperplasia have expanded in recent years. Saw palmetto, the most widely used complementary medication, is less effective than standard medical therapy but has fewer side effects. Although non-selective alpha blockers provide rapid relief of symptoms and are relatively inexpensive, they can cause dizziness and orthostatic hypotension. These effects occur less often with tamsulosin, a more selective alpha blocker. Finasteride, a 5alpha-reductase inhibitor, slowly reduces prostatic volume but is not as effective as alpha blockers, especially in men with a smaller prostate. Dutasteride, a new 5alpha-reductase inhibitor, has recently been labeled for the treatment of benign prostatic hyperplasia. Surgery may be appropriate initial treatment in patients with severe symptoms who are not at high risk for complications. Surgery may also be indicated in patients who have failed medical therapy or have recurrent infection, hematuria, or renal insufficiency. Transurethral resection of the prostate is effective in most patients, but it carries some risk of sexual dysfunction, incontinence, and bleeding. Surgical procedures that use thermal microwave or laser energy to reduce hyperplastic prostate tissue have recently become available. In general, the newer procedures are less expensive than transurethral resection of the prostate and have fewer complications; however, the need for retreatment is somewhat greater with these less invasive techniques.
ABSTRACT: Benign prostatic hyperplasia is a common condition affecting older men. Typical presenting symptoms include urinary hesitancy, weak stream, nocturia, incontinence, and recurrent urinary tract infections. Acute urinary retention, which requires urgent bladder catheterization, is relatively uncommon. Irreversible renal damage is rare. The initial evaluation should assess the frequency and severity of symptoms and the impact of symptoms on the patient's quality of life. The American Urological Association Symptom Index is a validated instrument for the objective assessment of symptom severity. The initial evaluation should also include a digital rectal examination and urinalysis. Men with hematuria should be evaluated for bladder cancer. A palpable nodule or induration of the prostate requires referral for assessment to rule out prostate cancer. For men with mild symptoms, watchful waiting with annual reassessment is appropriate. Over the past decade, numerous medical and surgical interventions have been shown to be effective in relieving symptoms of benign prostatic hyperplasia. Alpha blockers improve symptoms relatively quickly. Although 5-alpha reductase inhibitors have a slower onset of action, they may decrease prostate size and alter the disease course. Limited evidence shows that the herbal agents saw palmetto extract, rye grass pollen extract, and pygeum relieve symptoms. Transurethral resection of the prostate often provides permanent relief. Newer laser-based surgical techniques have comparable effectiveness to transurethral resection up to two years after surgery with lower perioperative morbidity. Various outpatient surgical techniques are associated with reduced morbidity, but symptom relief may be less durable.

Predicting the Risk of Recurrence After Surgery for Prostate Cancer - Point-of-Care Guides
ABSTRACT: In the United States, prostate cancer is the most common solid tumor malignancy in men and second to lung cancer as the leading cause of cancer deaths in this group. Even though prostate cancer is responsible for 40,000 deaths per year, screening programs are a matter of controversy because scientific evidence is lacking that early detection decreases morbidity and mortality. Furthermore, treatment decisions are difficult to make because of the generally indolent nature of prostate cancer and because it tends to occur in older men who often have multiple, competing medical illnesses. Depending on the specific situation, radical prostatectomy, radiotherapy or watchful waiting (observation) will be the most appropriate management option. In general, localized cancer is best treated with surgical removal of the prostate gland or radiotherapy. Hormone deprivation therapy is the primary method of controlling metastatic prostate cancer. At present, chemotherapy cannot cure disseminated prostate cancer. Watchful waiting is a reasonable management alternative for prostate cancer in an older patient or a patient with other serious illnesses.
