Table 1 of the article “Treatment of Prostatitis” (May 15, 2000, page 3015) contained an error. The first two elements in the diagnostic test column were inadvertently transposed; that is, the pre- and postmassage test should have been listed first, while the Stamey-Meares four-glass test should have been listed second. The corrected table is reprinted below.
TABLE 1 Interpretation of Two Diagnostic Tests for Prostatitis
| Diagnostic test | Test components | |||
|---|---|---|---|---|
| Pre- and postmassage test (PPMT) | Midstream urine culture* | Expressed prostatic secretions‡ | ||
| Stamey-Meares four-glass test | Premassage urine culture* | Premassage urine microscopy† | Postmassage urine culture‡ | Postmassage Urine microscopy† |
+ = Positive; − = negative; ABP = acute bacterial prostatitis; CPPS = chronic pelvic pain syndrome.
*—Negative result is no bacterial growth. Positive result is growth of a single bacterial species (>100,000 colony forming units per mL).
†—Negative result is <10 white blood cells per high-power field. Positive result is >10 to 20 white blood cells per high-power field.
‡—Positive result is significant bacteriuria in the postmassage specimen (any bacteria if the premassage urine is sterile or colony count per mL is at least 10 times greater than premassage count).
