Urinary flow rates were measured in a randomly selected community sample of more than 2,000 men 40 to 79 years old with no history of prostate surgery, prostate cancer or certain other diseases known to interfere with normal voiding. Peak urinary flow rates decreased from a median of 20.3 ml. per second in men 40 to 44 years old to 11.5 ml. per second for men 75 to 79 years old, while voided volumes decreased from a median of 355.5 to 222.5 ml. for the same age ranges. Peak flow rates of less than 10 ml. per second were found in 6% of the men aged 40 to 44 years, increasing to 35% among men aged 75 to 79 years. Urological standards for peak urinary flow rate should be based on community data, and should account for age and voided volume. Our study may serve as the starting point for the development of community-based flow rate normal ranges. Nomograms are given to permit estimating flow rate percentiles as a function of age and voided volume.
在一个随机选取的社区样本中，对2000多名40至79岁、无前列腺手术史、前列腺癌或其他已知会干扰正常排尿的特定疾病史的男性进行了尿流率测量。最大尿流率从40至44岁男性的中位数每秒20.3毫升降至75至79岁男性的每秒11.5毫升，而在相同年龄范围内，排尿量从中位数355.5毫升降至222.5毫升。在40至44岁的男性中，6%的人最大尿流率低于每秒10毫升，而在75至79岁的男性中，这一比例增至35%。尿流率的泌尿外科标准应基于社区数据，并应考虑年龄和排尿量。我们的研究可作为制定基于社区的尿流率正常范围的起点。文中给出了列线图，以便根据年龄和排尿量估算尿流率百分位数。
