The correlation between urodynamic and cystoscopic findings in elderly men with voiding complaints.

PURPOSE We evaluated the urethrocystoscopic findings and results of urodynamic studies in elderly men with voiding complaints. MATERIALS AND METHODS A total of 492 consecutive patients with voiding complaints underwent a standardized screening program, including transrectal ultrasonography of the prostate, urodynamic investigations with pressure-flow study analysis and flexible urethrocystoscopy. RESULTS A significant correlation was found between bladder trabeculation and grade of bladder outlet obstruction. Detrusor instability correlated significantly with grade of trabeculation. Grade of obstruction showed a clear correlation with prostatic occlusion of the urethra and the presence of a middle lobe at cystoscopy. CONCLUSIONS The findings at urethrocystoscopy correlate well with those of urodynamic investigations.
