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†

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†

Type of prostatitis	Test findings
Acute bacterial prostatitis	+	+	Avoid massage in ABP	Avoid massage in ABP
Chronic bacterial prostatitis	−	�	+	+
Chronic nonbacterial prostatitis/CPPS–inflammatory	−	�	−	+
Chronic nonbacterial prostatitis/CPPS–noninflammatory	−	−	−	−
Asymptomatic prostatitis	�	�	+	+

+ = 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).
