【Abstract】ObjectiveTo investigate the correlation of prostate volume with maximal urinary flow rate and international prostate symptom score(IPSS) in benign prostatic hyperplasia (BPH) patients.Methods150 cases of benign prostatic hyperplasia admitted to hospital from April,2013 to May,2014 were selected as study objects.All cases were given urodynamic examination,transrectal ultrasound and IPSS.According to Qmax,all patients were divided into group A(Qmax≤10 ml/s,91 cases),Group B (Qmax=11~15 ml/s,38 cases) and group C(Qmax>15 ml/s,21 cases).Results Average Qmax of all patients was(8.1±2.5)ml/s,average TPV was(46.7±13.4)ml,average TZV was(28.9±7.2)ml,and average IPSS was(23.5±6.4)points.The TPV,TZV and IPSS of the group B were lower than those of the group A,but there was no statistically significant difference between two groups(P>0.05).The TPV,TZV and IPSS of the group C were also significantly lower than those of the group A,and difference was statistically significant(P<0.01).The TPV,TZV and IPSS of the group C were lower than those of the group B,but there was no statistically significant difference between two groups(P>0.05).Spearman correlation analysis showed that Qmax had significantly negative correlation with TPV and TZV(P<0.05),while IPSS had significantly positive correlation with TPV and TZV (P<0.05).And the Qmax had significantly positive correlation with IPSS (P<0.05).ConclusionThe prostate volume is associated with Qmax and IPSS in patients with benign prostatic hyperplasia.The greater the prostate volume,the lower the Qmax and the more severe the lower urinary tract symptoms. 【Key words】benign prostatic hyperplasia;prostate volume;maximal urinary flow rate;international prostate symptom score
良性前列腺增生(benign prostatic hyperplasia,BPH)是泌尿外科老年男性最為常見的疾病,病理性增大的前列腺腺體對(duì)患者尿道通暢造成不同程度的影響,從而導(dǎo)致排尿困難、尿頻、泌尿系統(tǒng)感染、血尿等一系列癥狀的產(chǎn)生[1]。對(duì)BPH患者病情評(píng)估及治療方式選擇往往需要結(jié)合患者臨床癥狀、尿動(dòng)力學(xué)檢查及超聲影像學(xué)等進(jìn)行綜合判斷。本研究對(duì)患者前列腺體積(prostate volume,PV)與最大尿流率(maximal urinary flow rate,Qmax)、國(guó)際前列腺癥狀評(píng)分(international prostate symptom score,IPSS)間的相關(guān)性進(jìn)行探討,進(jìn)一步了解BPH臨床病理變化特點(diǎn),為其早期診治提供一定的參考。
1資料與方法1.1一般資料選擇2013年4月至2014年5月我院收治的BPH患者共150例,年齡52~84歲,平均(64.8±7.2)歲;病程5個(gè)月~13年,平均(4.1±1.6)年;颊咝g(shù)前主訴不同程度尿頻、排尿不盡、尿細(xì)線、夜尿頻多等,其中28例合并有尿潴留現(xiàn)象。生活質(zhì)量評(píng)估(quality of life assessment,QOL)為3~6分,平均(5.1±0.6)分。所有病例均行前列腺特異性抗體(prostate specific antigen,PSA)檢查,結(jié)合臨床癥狀、直腸指檢、常規(guī)尿道膀胱鏡等檢查確診,且排除尿道狹窄、前列腺癌的可能。IPSS根據(jù)醫(yī)生接診時(shí)參照國(guó)際前列腺癥狀評(píng)分表詢問患者獲得。
1.2檢查方法
1.2.1Qmax的檢查所有患者均于治療前2~3 d及治療后1個(gè)月進(jìn)行尿動(dòng)力學(xué)檢測(cè)。儀器采用四川成都維信公司的Nidoc970A尿流動(dòng)力學(xué)分析儀,留置尿管患者在拔除尿管2~3小時(shí)進(jìn)行測(cè)定。根據(jù)不同的檢查項(xiàng)目取相應(yīng)的體位,先囑咐患者自行排尿,測(cè)定自由尿流率。然后常規(guī)消毒鋪巾,經(jīng)尿道置入F8膀胱雙腔測(cè)壓導(dǎo)管并固定,測(cè)膀胱殘余尿量,再經(jīng)肛門置入F12直腸測(cè)壓管,將儀器調(diào)零和傳感器校正,并確認(rèn)測(cè)壓感與分析儀的妥善連接。將生理鹽水以50 ml/min的恒速向膀胱內(nèi)灌注,行壓力尿流率測(cè)定,記錄患者Qmax。并根據(jù)Qma
