Urodynamic Analysis of Men with Normal Prostate Less Than 20 gm Combined with Lower Urinary Tract Symptoms

ABSTRACT

PURPOSE: The cause of lower urinary tract symptoms(LUTS) without diseased causes of urodynamics in men is unclear. The aim of this study was to elucidate reliability of difference of LUTS and its treatment by urodynamic study. MATERIALS AND METHODS: Urodynamic study of 124 patients with LUTS were evaluated by age, international prostate symptom score(IPSS) and PSA. The group of patients were divided according to the chief complaint as irritative symptom group(n=72) and obstructive symptom group(n=42). RESULTS: In irritative symptoms group, 29 patients showed stable bladder which combined with bladder outlet obstruction(BOO)(n=11), detrusor underactivity(DU)(n=2) and normal finding(n=6). 43 patients showed unstable bladder which combined with BOO(n=11) and only detrusor overactivity(DO)(n=32). In obstructive symptoms group, 41 patients showed stable bladder that combined BOO(n=13), DU(n=17) and normal finding(n=11), 11 patients showed unstable bladder that BOO(n=1) and DO(n=10). CONCLUSION: LUTS in men are common and often misdiagnosed. Thus, We must treat the LUTS patients with individual therapy based on urodynamic findings.
