The Efficacy of Terazosin in the Management of Chronic Pelvic Pain Syndrome (CPPS): Comparison between Category IIIa and IIIb
2006
Purpose: To evaluate the efficacy of terazosin in chronic pelvic pain syndrome (CPPS) and compare the effect of terazosin between CPPS IIIa and IIIb. Materials end Methods: Between January 2004 and February 2005, CPPS patients, aged 45 or below, with a small size prostate (≤25ml), were enrolled in this study. The study comprised of 127 patients (CPPS category IIIa; 71, CPPS category IIIb; 56), who were randomly placed into one of two groups; the terazosin (T) and non-terazosin (non T) groups. The terazosin group was given 3-4mg/day of terazosin for 12 weeks. In all patients, the urinalysis, expressed prostatic massage (EPS), uroflowmetry, National Institute of Health-Chronic Prostatitis Symptom Index (NIHCPSI) and transrectal ultrasonography (TRUS) were checked at the initial visit. After 12 weeks, the NIH-CPSI and uroflowmetry were evaluated, and the change in the NIH-CPSI domain scores and maximal flow rate (Qmax) between the two groups evaluated; a sub-analysis was also performed between categories IIIa and IIIb. Results: The changes in the NIH-CPSI domains (pain, voiding symptom, quality of life, total) and Qmax of the T group were more significantly improved than those in the non T group (p 0.05). In category IIIb (n=56), the T group (n=29) showed significant improvements in all NIH-CPSI domains and the Qmax (p 0.05). Comparing both category IIIb groups, the T group showed a greater improvement in the pain score in the NIH-CPSI domains and the Qmax than the non-T group. Conclusions: Terazosin was effective in all domains of the symptom score and in the Qmax for CPPS. (Korean J Urol 2006;47:1191-1196) ????????????????????
