手术前的

From April to October 2003, a total of 40 patients aged 58 to 86 years (mean: 69.3 yr) were randomized into two comparable groups; one underwent bipolar TURP and the other received monopolar TURP. Pre-operative and post-operative serum sodium concentration, hemoglobin level, resection time, blood loss and weight of specimen were evaluated.

方怯 从2003年4月至10月，总共收集40位良性摄护腺的病患，以随机的方式接受双极电刀（22位）及单极电刀（18位）的治疗，分析两组的手术时间、刮除的病理重量、流血量、术前及术后的钠离子变化与术后6个月及1年的I-PSS、Qmax的比较。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
