The pH of urine samples from patients suffering symptoms suggesting urinary infection (e.g. dysuria, frequency, urgency) was measured while the patients were symptomatic and again when they had become asymptomatic. There was no correlation between the urine pH and the incidence or number of symptoms. No differences were observed between either the distribution or means of urine pH values in symptomatic and asymptomatic patients. There were also no significant differences in either symptomatology or urine pH between patients with significant bacteriuria and those without significant bacteriuria. These results cast doubt upon the traditional (but unproved) belief that alkalinizing the urine helps to reduce symptoms of dysuria and/or frequency, whether or not associated with urinary infection.
对出现提示泌尿系统感染症状（如排尿困难、尿频、尿急）的患者，在其有症状时以及症状消失后分别测量尿液样本的pH值。尿液pH值与症状的发生率或数量之间无相关性。有症状和无症状患者的尿液pH值分布或均值均无差异。有明显菌尿症的患者与无明显菌尿症的患者在症状或尿液pH值方面也无显著差异。这些结果对传统（但未经证实）的观点提出了质疑，即无论是否与泌尿系统感染相关，碱化尿液有助于减轻排尿困难和/或尿频的症状。
