【摘要】：目的探討高齡良性前列腺增生(BPH)中小體積前列腺伴膀胱出口梗阻(BOO)患者的尿動(dòng)力學(xué)特點(diǎn)。方法年齡70歲的高齡BPH中有BOO的患者115例,根據(jù)前列腺體積分為前列腺體積≤30 ml組45例,30 ml組70例,比較兩組年齡、血清前列腺特異性抗原(TPSA)水平、殘余尿量、最大尿流率(Qmax)、平均尿流率、排尿量、排尿時(shí)間、膀胱順應(yīng)性、Qmax時(shí)膀胱壓力、逼尿肌收縮能力。結(jié)果前列腺體積≤30 ml組年齡、Qmax時(shí)膀胱壓力及Qmax時(shí)逼尿肌壓力均明顯低于前列腺體積30 ml組,而殘余尿量明顯高于前列腺體積30 ml組(P0.05);前列腺體積≤30 ml組逼尿肌收縮乏力發(fā)生率明顯高于前列腺體積30 ml組(χ~2=3.86,P=0.049)。結(jié)論小體積前列腺的BPH,在經(jīng)尿動(dòng)力學(xué)檢查判斷為BOO時(shí),合并發(fā)生膀胱排空障礙及逼尿肌收縮能力降低的可能性更大。
