Abstract

Among the 65 patients undergoing transurethral resection of the prostate from 1985 to 1988, the complication incidence was significantly higher in 25 patients whose weight of resected prostate was above 20 gm than in 40 patients below 20 gm (p<0.05). So to choose mote proper surgical method, the results of operation, motality and morbity of these 25 TURP patients were compared with 35 open prostatectomy patients whose weight of resected prostate was between 20 gm and 60 gm during same period. The mean incidence of complication for open prostatectomy (60%) was nearly twice that of the TURP (32%) (p<0.05). The age of the patient had no significant influence on the incidence of complication in both groups. In case of the weight of resected prostate below 40 gm complication incidence for the TURP (26.3%) was significantly lower compared with open prostatectomy(66.7%) (p<0.05), but in case of above 40 gm there was no significant difference in both groups. In case of the length of resection below 120 min complication incidence was significantly low in TURP (21.4%) compared with open prostatectomy (61.5%) (p<0.05), but in case of above 120 min. there was no significant difference in both groups. In the open prostatectomy there was no increase in complication incidence by the weight of the gland and the operation time, but in TURP, complicat,40 gm incidence was definitely increased when either weight of the resected prostate was above 40 gm or length of resection was above 120 minutes. Therefore, it seems that TURP is preferable surgical method for benign prostatic hypertrophy unless open surgery is necessarily indicated.
