Urodynamic examinations (cystometry with simultaneous recording of anal sphincter electromyography, urethral pressure profile and uroflowmetry) were performed in 46 patients with benign prostatic hypertrophy. The preoperative cystometry showed detrusor hyperreflexia in 25% of total cases and it was thought that detrusor hyperreflexia was a cause of pollakisuria which was one of the chief complaints of patients with benign prostatic hypertrophy. The urethral pressure profile of these patients had significantly elongated functional profile length and prostatic profile length. Postoperatively, these lengths were significantly shortened. These lengths showed a tendency to correlate with the size of adenoma and its clinical diagnostic value was discussed. In uroflowmetry, maximum flow rates and average flow rates were decreased preoperatively, but increased postoperatively. The correlation between voided volume and these two parameters was increased postoperatively. Significant difference could not be showed in uroflowmetry between the small sized adenoma group and the large sized adenoma group. Objectively, its results showed that the difficulty of micturition was never correlated with the size of adenoma. We tried objective analysis of micturition disturbance by uroflowmetry and emphasized that the difficulty of micturition was caused by organic mechanical obstruction in patients with benign prostatic hypertrophy.
