摘 要:目的研究排尿体位对健康青年男性尿流测定(UFM)和残余尿(PVR)的影响,探讨男性更佳的排尿体位,为临床应用UFM评估膀胱功能和规范测定方法提供参考。方法对新乡医学院第一附属医院43名在校男性医学生(22~28岁,入学体检健康,无下尿路症状)分别于站立位、前弯曲坐位和坐位3种体位进行UFM,每次排尿后立即用B超测定PVR。比较3种体位排尿量(VV)、最大尿流率(Qmax)、平均尿流率(Qave)和PVR。结果参与者在站立位、前弯曲坐位和坐位的VV中位数分别为211.6(169.5,265.9)mL、206.8(173.5,262.8)mL和203.7(175.9,260.0)mL,三组间比较差异无统计学意义(P=0.486);Qmax分别为(26.00±2.33)mL/s、(26.41±2.12)mL/s和(23.50±2.52)mL/s;Qave分别为(14.03±2.21)mL/s、(14.27±2.18)mL/s和(11.77±1.89)mL/s;PVR分别为(9.97±2.26)mL、(9.43±1.97)mL和(12.10±3.28)mL,参与者在站立位和前弯曲坐位的Qmax、Qave高于坐位测定值,PVR低于坐位测定值,差异有统计学意义(P<0.05)。参与者在站立位与前弯曲坐位的Qmax、Qave和PVR差异均无统计学意义(P>0.05)。结论青年男性在站立位和前弯曲坐位均有利于排空膀胱,推荐这2种体位作为膀胱排尿的首选体位。Objective To investigate the impacts of voiding positions on urinary flow measurement(UFM)and post voided residual(PVR)in young males,to explore a better voiding position,and to provide reference for the clinical application of UFM.Methods A total of 43 male medical students(22-28 years old,all healthy with no lower urinary tract symptoms)from the First Affiliated Hospital of Xinxiang Medical College were enrolled.UFM was recorded in standing position,forward-bentding sitting position and sitting position,respectively.PVR was determined with B-ultrasound immediately after each voiding.Voided volume(VV),maximum urine flow rate(Qmax),average urine flow rate(Qave)and PVR were compared.Results In the standing,forward-bending sitting,and seating positions the VV were 211.6(169.5,265.9)mL,206.8(173.5,262.8)mL,and 203.7(175.9,260.0)mL,respectively,with no significant difference(P=0.486);the Qmax were(26.00±2.33)mL/s,(26.41±2.12)mL/s,and(23.50±2.52)mL/s,respectively;the Qave were(14.03±2.21)mL/s,(14.27±2.18)mL/s,and(11.77±1.89)mL/s,respectively;the PVR were(9.97±2.26)mL,(9.43±1.97)mL and(12.10±3.28)mL,respectively.The Qmax and Qave in standing position and forward-bending sitting position were significantly higher than those in the sitting position,while the PVR was lower than that in the sitting position,with statistically significant difference(P<0.05).There were no significant differences in Qmax,Qave and PVR between the forward-bending sitting and standing positions(P>0.05).Conclusion Standing position and forward-bending seating position are beneficial for emptying the bladder,and these two positions are recommended for young men to urinate as the first choice.
