Abstract

Although transurethral prostatectomy is the most common treatment method of benign prostatic hyperplasia, the exact indication and efficacy of this method is variable and controversial. We performed this study to determine the efficacy of transurethral prostatectomy on men with moderate symptoms or benign prostatic hyperplasia. The efficacy parameters evaluated included the change of maximal flow rate, Boyarsky symptom score and the global assessment of voiding symptom by the patient after transurethral prostatectomy. The mean maximal flow rate improved 204% after transurethral prostatectomy, and the mean obstructive and irritative symptom scores decreased 84% and 59% respectively. But the irritative symptom score of unsatisfied patients decreased only. 41%. Over all, 80% of the patients were satisfied with the result of the operations. The improvement of the irritative symptoms is not expected after a transurethral prostatectomy, and therefore, the operative procedure is not indicated. But the symptoms of the unsatisfied patients were similar to the comparative group (healthy men over 50 years of age). Although this comparative group had nocturia (11%), frequency (32%), urgency (29%), they felt no necessity for special medical attention, but hesitancy, intermittency, terminal dribbling and dysuria led the patient to seek help in a hospital.
