IMPORTANCE Accurate diagnosis of urinary tract infection after pelvic organ prolapse (POP) surgery is essential to postoperative care. OBJECTIVE Our aim was to determine the agreement between the urinalysis of a clean-catch versus a straight catheter urine specimen in women who underwent vaginal surgery for POP. STUDY DESIGN This was a cross-sectional study evaluating patients after vaginal surgery for POP. A clean-catch and straight catheter urine specimen were collected at routine postoperative appointments. Routine urinalyses and urine cultures were performed for all patients. A urine culture yielding mixed urogenital flora (which includes Lactobacillus species), coagulase-negative staphylococci, and Streptococcus species was considered a contaminated result. The agreement between the characteristics of urinalysis obtained via the clean catch versus the straight catheter at 3 weeks postoperatively was evaluated using weighted κ statistic. RESULTS Fifty-nine participants enrolled. The agreement between the characteristics of urinalysis obtained via the clean catch versus the straight catheter was poor (κ = 0.018). The urine culture was more likely to be contaminated from the clean-catch urine specimen than from the straight catheter urine specimen (53.7% vs 23.1%).The positive and negative predictive values of leukocyte esterase on clean catch were 22.6% and 100%, respectively. CONCLUSIONS Diagnosing urinary tract infection based on contaminated urinalyses may lead to antibiotic overuse and misdiagnosis of postoperative complications. Our results can help educate health care partners and discourage the use of clean-catch urine specimens when assessing women who have recently undergone vaginal surgery.

盆腔器官脱垂阴道手术后，干净收集的尿液样本更容易被污染。

重要性 盆腔器官脱垂 (POP) 手术后尿路感染的准确诊断对于术后护理至关重要。目的 我们的目的是确定接受阴道 POP 手术的女性的清洁捕获尿液样本与直导尿管尿液样本的尿液分析之间的一致性。研究设计 这是一项横断面研究，评估 POP 阴道手术后的患者。在术后常规预约时收集干净的直导管尿液样本。对所有患者进行常规尿液分析和尿液培养。尿液培养产生混合泌尿生殖菌群（包括乳杆菌属）、凝固酶阴性葡萄球菌和链球菌属被认为是污染结果。术后 3 周，使用加权 κ 统计量评估通过清洁捕获与直导尿管获得的尿液分析特征之间的一致性。结果 59 名参与者注册。通过清洁捕获与直导尿管获得的尿液分析特征之间的一致性较差（κ = 0.018）。干净捕获的尿液标本比直导管尿液标本更容易被尿培养污染（53.7% vs 23.1%）。干净捕获的白细胞酯酶阳性和阴性预测值分别为22.6%和100%，分别。结论 根据受污染的尿液分析诊断尿路感染可能会导致抗生素的过度使用和术后并发症的误诊。我们的结果可以帮助教育医疗保健合作伙伴，并在评估最近接受过阴道手术的女性时阻止使用干净捕获的尿液样本。
