1. HIGH ENERGY TRANSURETHRAL MICROWAVE THERMOTHERAPY FOR THE TREATMENT OF PATIENTS INURINARY RETENTION (vol. 163, pp. 1457–1460)

Men in urinary retention due to benign prostatic hyperplasia who are treated with transurethral microwavethermotherapy will:

a) need general or spinal anesthesiab) have a 1-year re-treatment rate of 25%c) have an initial treatment success rate of 98%d) have the best results if the prostate is greater than 90 ml.e) have a success rate of 80% in patients with poor bladder control

2. EFFECTS OF A SAW PALMETTO HERBAL BLEND IN MEN WITH SYMPTOMATIC BENIGN PROSTATICHYPERPLASIA (vol. 163, pp. 1451–1456)

The mechanism of action of saw palmetto extracts in patients with benign prostatic hyperplasia is:

a) a blockadeb) inhibition of 5-a reductasec) epithelial contractiond) glandular atrophye) angiogenesis

3. HUMAN GLANDULAR KALLIKREIN 2: A POTENTIAL SERUM MARKER FOR PREDICTING THE ORGANCONFINED VERSUS NONORGAN CONFINED GROWTH OF PROSTATE CANCER (vol. 163, pp. 1491–1497)

In patients with organ confined compared to nonorgan confined prostate carcinoma:

a) the free prostate specific antigen (PSA) is lowerb) the total PSA is lowerc) the percent free PSA is higherd) there is no difference in any serum markere) human kallikrein 2 is less

4. A PHASE 2 STUDY OF RADIO FREQUENCY INTERSTITIAL TISSUE ABLATION OF LOCALIZED RENALTUMORS (vol. 163, pp. 1424–1427)

Radio frequency interstitial tissue ablation of localized renal tumors:

a) has no visual effect on the tumorb) decreases blood flow on color Doppler ultrasoundc) increases serum creatinined) decreases blood urea nitrogene) preserves nuclear detail

5. COMPLEXED PSA PROVIDES SIGNIFICANT ENHANCEMENT OF SPECIFICITY COMPARED WITH TOTAL PSAFOR DETECTING PROSTATE CANCER (vol. 163, pp. 1476–1480)

The advantage of measuring complex PSA compared to the free-to-total PSA ratio is:

a) savings due to only a single analyteb) absence of “quotient” bias resulting from division of 1 serum concentration result by anotherc) complex PSA provides improved specificity relative to total PSAd) complex PSA alone and the free-to-total ratio provide similar specificity enhancemente) all of the above
