Abstract

A clinical study was made on 330 cases of transurethral prostatectomy that were performed at the Department of Urology. Seoul Eulji General Hospital. Seoul and Daejeon Eulji General Hospital, Daejeon during the period from August, 1984 to July, 1992. Transurethral prostatectomy was per- formed on 309 cases of benign prostatic hyperplasia and 21 cases of prostatic cancer. 1. The mean age of all patients was 67.1 years(50-85 years) and the group of seventh decade was most common (40.5% in BPH and 55% in prostatic cancer). 2. The mean weight of resected prostatic tissue was 9.7 grams(3-45 grams) and the mean length of resection time was 68.6 minutes(30-125 minutes). The mean weight of resected tissue per minute was 0.23 grams. 3. The mean duration of postoperative urethral catheter indwelling was 6.3 days(2-14 days) and the mean period of postoperative hospitalization was 8.4 days(3-19 days). 4. Total complication rate was 15.5% and complications were as follows; failure to void(4.6%) bleeding(3.9%), incontinence(2.7%), urethral stricture(1.8%), secondary resection due to in- adequate resection(1.2%), extravasation(0.9%), epididymitis(0.3%), hyponatremia(0.3%), etc. One patient was dead due to deterioration of associated disease postoperatively. 5. We undertook follow-up assessment of voiding symptom with Boyarsky symptom score system on 148 cases of BPH group. The mean obstructive and irritative symptom scores decreased 84 % and 48%, respectively. We also evaluated the urinary flow rate in 102 cases of 148 cases and the mean peak flow rate improved 98%. The observed changes in symptom score and urinary flow rate was statistically and clinically significant(p<0.01).
