title: Clinical evaluation of the results of open or transurethral surgery for prostate hypertrophy.
abstract: We evaluated the outcome of surgery for prostate hypertrophy through measurement of the urine flow rate and the Boyarsky symptom score. The study covered 108 patients admitted to Showa University School of Medicine, Fujigaoka Hospital. Thirty-eight had been admitted for retropubic prostatectomy and the remaining 70 patients for transurethral resection of the prostate. Their ages ranged from 48 to 84 years, with an average age of 64.4 years. The urine flow rate was measured before and after prostatic operation using Dantec Urodyn 1000. The symptom scores were calculated according to the Boyarsky symptom score. The Student's t test was used for statistical analysis. Frequency (daytime, nighttime) was the most common preoperative symptom (97.2%, 96.3%), followed by impairment of stream (88.0%), and intermittency (78.7%). Frequently observed symptoms tended to raise the symptom scores. The period of admission, age and prostatic size did not correlate with the preoperative urine flow rate and symptom score. Significant improvements in the urine flow rate occurred after the operation. Frequency (daytime, nighttime) was the most common postoperative symptom (82.7%, 81.1%), followed by urgency (37.0%), then terminal dribbling (32.2%). Of 39 patients who were evaluated by symptom score and urine flow simultaneously, 6 patients (15.1%) failed to show improvement in 1 of the 2 evaluations, while 9 (23.1%) patients failed to show improvement in either. The irritative symptoms (frequency, urgency) tended not to show significant postoperative improvement.
