The between-observer variation was evaluated through three independent estimates of preoperative prostatic weight in each of 40 patients. Error in the estimates was of considerable magnitude irrespective of size of prostates. Experienced urologists did not attain a more reliable estimate than unexperienced doctors. Only about 2/3 of estimates were correct within a range of +/- 25 g. However, there was a statistically significant correlation between estimated and actual operative prostatic weight.
通过对40例患者术前前列腺重量的三次独立评估来评价观察者间的差异。无论前列腺大小如何，估计值的误差都相当大。经验丰富的泌尿科医生并没有比经验不足的医生获得更可靠的估计值。只有约2/3的估计值在±25克范围内是正确的。然而，估计的和实际手术时的前列腺重量之间存在统计学上的显著相关性。
