As part of a randomized, controlled, trial conducted by the Department of Veterans Affairs Cooperative Studies Program comparing the effectiveness of transurethral resection of the prostate to watchful waiting, we evaluated 707 men with mild to severe symptoms of benign prostatic hyperplasia (BPH). We examine the relationships among patient reported symptoms, quality of life responses, peak urine flow rates and post-void residual urine estimates. Correlations among responses to symptom and quality of life interviews, urine flow results and residual urine volume were low (less than 0.20). However, multivariate correlation analysis showed that patient reported irritative symptoms, such as urgency, frequency and nocturia, were associated with quality of life responses, while patient reported obstructive symptoms, peak urinary flow rates and post-void urine estimates were unrelated to diminished quality of life. Since the extent to which BPH interferes with the life-style is likely to influence the decision of the patient to seek medical evaluation, the lack of association between quality of life and obstructive symptoms may result in misdirected diagnostic evaluations. This may have a large role in the controversies regarding assessments of symptomatic BPH, guidelines for surgical intervention and outcomes of treatment. Further study is required to determine the influence of diminished quality of life and irritative symptoms on the outcomes of treatments for BPH.
作为美国退伍军人事务部合作研究项目开展的一项随机对照试验的一部分,该试验比较了经尿道前列腺切除术与观察等待的效果,我们评估了707名有轻至重度良性前列腺增生(BPH)症状的男性。我们研究了患者报告的症状、生活质量反应、最大尿流率和排尿后残余尿量估计值之间的关系。症状和生活质量访谈的反应、尿流结果和残余尿量之间的相关性较低(小于0.20)。然而,多变量相关性分析表明,患者报告的刺激性症状,如尿急、尿频和夜尿症,与生活质量反应相关,而患者报告的梗阻性症状、最大尿流率和排尿后尿量估计值与生活质量下降无关。由于BPH干扰生活方式的程度可能会影响患者寻求医学评估的决定,生活质量与梗阻性症状之间缺乏关联可能会导致诊断评估方向错误。这可能在有关有症状BPH的评估、手术干预指南和治疗结果的争议中起很大作用。需要进一步研究以确定生活质量下降和刺激性症状对BPH治疗结果的影响。
