摘　　要：目的研究健康青少年男性体重指数(BMI)与尿流率的相关性。方法选择新乡医学院2020级本科男生439名,年龄17~22岁,使用移动式家庭电子尿流率仪进行自由尿流率检查,志愿者在正常尿意时于卫生间主动排尿,在自然状态下排尿,电子尿流率仪通过蓝牙设备自动记录最大尿流率、平均尿流率、2 s尿流率、排尿时间、尿流时间和达峰时间,并绘制尿流曲线。根据尿流动力学检查结果,按照尿量分为3组:A组132例,尿量小于150 mL;B组249例,尿量150~<400 mL;C组58例,尿量大于或等于400 mL。根据BMI分4组:BMI<18.5 kg/m2(偏瘦组),BMI 18.5~<24.0 kg/m2(正常组),24.0~<28.0 kg/m2(超重组),BMI≥28 kg/m2(肥胖组)。在不同尿量范围内分别分析BMI与最大尿流率、平均尿流率、2 s时尿流率、排尿时间、尿流时间和达峰时间的相关性。结果各尿量分段的不同BMI值人群的平均年龄、居住地城市/农村比率、吸烟率、饮酒率差异均无统计学意义(P>0.05)。在健康青少年男性中,随着尿量的增加,最大尿流率也逐渐增加。对于A组的人群,不同BMI人群的最大尿流率、平均尿流率、2 s尿流率、排尿时间、尿流时间和达峰时间差异无统计学意义(P>0.05)。对于C组人群,不同BMI人群的最大尿流率、平均尿流率、2 s尿流率、排尿时间、尿流时间和达峰时间差异无统计学意义(P>0.05)。对于B组人群,不同BMI人群的2 s尿流率、排尿时间和尿流时间差异均有统计学意义(P<0.05)。组间两两比较结果显示为:肥胖人群2 s尿流率明显高于体型偏瘦人群,肥胖人群排尿时间和尿流时间明显短于体型偏瘦人群。结论在正常尿量范围(150~<400 mL)内,健康青少年男性中最大尿流率随着BMI的增加而逐渐增加,2 s尿流率随着BMI的增加显著增高,排尿时间和尿流时间随着BMI的增加显著降低。Objective To study the correlation between body mass index(BMI)and urinary flow rate in healthy male adolescents.Methods A total of 439 male undergraduates(17-22 years old)from Xinxiang Medical College of 2020 were selected.The free urine flow rate was examined by using a mobile home electronic urine flow meter.The volunteers urinated in the toilet when they had normal urination desire and urinated in the natural state.The electronic urine flow meter automatically recorded the maximum urine flow rate,average urine flow rate,urine flow rate at 2nd second,urination time,urine flow time and peak time through the bluetooth device,and recorded the urine flow curve.Based on the oca-come of urodynamic examination,the patients were divided into three groups according to the urine volume:group A,132 patients with urine volume<150 mL;group B,249 patients with urine volume between 150-<400 mL;group C:58 patients with volume≥400 mL.According to BMI,they were divided into four groups:BMI<18.5 kg/m2(underweight group),BMI between 18.5-<24.0 kg/m2(normal group),BMI between 24.1-<28.0 kg/m2(abnormal group),and BMI≥28.0 kg/m2(obese group).The correlation between BMI and maximum urine flow rate,average urine flow rate,urine flow rate 2nd second,urination time,urine flow time and peak time were compared in different ranges of urine volume.Results There were no significant differences in average age,urban/rural ratio,smoking rate and alcohol consumption rate among people with different BMI values in different urine volume groups(P>0.05).In healthy male adolescents,with the increase of urine volume,the maximum urine flow rate also showed a trend of gradual increase.For people in group A,there were no significant differences in the maximum urine flow rate,average urine flow rate,urine flow rate 2nd second,urination time,urine flow time and peak time among different BMI groups(P>0.05).In group C,there were no significant differences in the maximum urine flow rate,average urine flow rate,urine flow rate at 2nd second,urination time,
