Urodynamic Findings of Chronic Nonbacterial Prostatitis Patients with Urinary Symptoms

PURPOSE: Chronic nonbacterial prostatitis represents a major portion of all the chronic prostatitis syndromes. Yet its pathogenesis is not definitive. Therefore, the treatment of chronic nonbacterial prostatitis in men is unclear. In this study, the patients with chronic nonbacterial prostatitis, especially those with complaints of voiding difficulty, were analyzed with conducting a urodynamic study to search for the pathophysiology and the effective treatments.
Sixty men (mean age: 38.9+/-8.3 years) diagnosed with chronic nonbacterial prostatitis were included in this study after excluding the patients with prostatic infection via the standard bacteriological methods. Thereafter, the patients were evaluated urodynamically, including measurements by uroflowmetry, cystometry and a pressure flow study.
According to their symptoms, 37 (61.7%) patients complained of frequency, 28 (46.7%) patients complained of a weak stream, 10 (16.7%) patients complained about urgency, and 5 (8.3%) patients complained about pelvic pain. Of the 60 patients, detrusor underactivity (DU), detrusor overactivity (DO), and bladder outlet obstruction (BOO) were found in 19 (31.7%), 12 (20.0%), and 11 (18.3%) patients respectively; there were equivocal findings in 30.3% of patients.
This study demonstrated that 42 (70%) patients suffering with chronic nonbacterial prostatitis had different urodynamically abnormal patterns such as DU, DO and BOO. A urodynamic study may to be useful in establishing a correct diagnosis and for launching the appropriate therapy for the selected group of patients who were not helped by general treatments.
