Methods The single uroflow of 27 healthy young male volunteers ( mean a吕e 26. 2 ye脯， range 19 - 37) W副 measured with the portable home electronic uroflowmeter in out - patient department. Further , the portable home electronic uroflowmeter w田 set up at home and a1 1voidings during a 24 - hour period were recorded. It produced a total of 156 voidings using the portable home electronic uroflowmeter. The median voiding frequency w幽 5.78. Bland - Altm皿 was used to analysis the agreement between the single office and multiple home uroflowmetry. Results The 95)毛 limits of 哺eement of Qm础 and Qave are both beyond the clinical acceptable limits(5% x50mVs)They are 44.4 % (12127) ,48. 15% (13/27) of Qmax and Qave within the clinical acceptable lim山.
