Operating time, the weight of the prostate, blood loss, and bleeding rate (ml/min) were recorded during transurethral prostatectomy in 417 patients. There were significant correlations between prostate weight and blood loss (r = .589; P less than 0.001) and between operating time and blood loss (r = .551; P less than 0.0001). Bleeding rate was significantly correlated with prostate weight (r = .399; P less than 0.0001) but not with operating time. Results of multiple regression analysis confirmed that bleeding was more closely related to prostate weight than to operating time. Operating time appears to be an iatrogenic factor in blood loss during transurethral prostatectomy.
在417例经尿道前列腺切除术患者中记录了手术时间、前列腺重量、失血量和出血率（毫升/分钟）。前列腺重量与失血量之间存在显著相关性（r = 0.589；P < 0.001），手术时间与失血量之间也存在显著相关性（r = 0.551；P < 0.0001）。出血率与前列腺重量显著相关（r = 0.399；P < 0.0001），但与手术时间无关。多元回归分析结果证实，出血与前列腺重量的关系比与手术时间的关系更为密切。手术时间似乎是经尿道前列腺切除术期间失血量的一个医源性因素。
