OBJECTIVE
To investigate the effect of time since last urination on chlamydial positivity rates in men.
METHODS
Prospective study on men attending a genitourinary medicine clinic who were asked for the last time of their urination before obtaining their urine sample for testing for Chlamydia trachomatis with the Cobas Amplicor polymerase chain reaction (PCR) assay.
RESULTS
Of the total of 1649 men studied, 621 (37.6% (95% CI 35.3% to 39.9%)) had a voiding interval of less than 2 hours. There was no statistical evidence of a difference in the positivity rate of chlamydial infection among men with a voiding interval of less than 2 hours (106/621, 17.1%) and that of men with a voiding interval of 2 hours or longer (170/1028, 16.5%); difference in proportions 0.5% (95% CI to 3.2% to 4.3%), p = 0.779.
CONCLUSION
Voiding interval does not have a significant impact on the performance of the Cobas Amplicor PCR assay in men.
目的
研究上次排尿时间对男性衣原体阳性率的影响。
方法
对前往泌尿生殖医学诊所的男性进行前瞻性研究，在采集尿液样本以通过Cobas Amplicor聚合酶链反应（PCR）检测沙眼衣原体之前，询问他们上次排尿的时间。
结果
在总共1649名研究对象中，621人（37.6%（95%可信区间35.3%至39.9%））排尿间隔时间少于2小时。排尿间隔时间少于2小时的男性衣原体感染阳性率（106/621，17.1%）与排尿间隔时间为2小时或更长时间的男性（170/1028，16.5%）之间，没有统计学证据表明存在差异；比例差异为0.5%（95%可信区间为3.2%至4.3%），p = 0.779。
结论
排尿间隔时间对男性Cobas Amplicor PCR检测的结果没有显著影响。
