良性前列腺增生;經(jīng)尿道980nm激光汽化術(shù);經(jīng)尿道前列腺電切術(shù)

良性前列腺增生(benign prostate hyperplasia,BPH)是引起中老年男性排尿障礙的常見(jiàn)疾病,隨著年齡的增長(zhǎng),其發(fā)病率逐漸增加[1-2]。經(jīng)尿道前列腺電切術(shù)(transurethral resesction of prostate,TURP)是目前BPH治療的金標(biāo)準(zhǔn)[3],但它仍存在如術(shù)中出血較多,易并發(fā)經(jīng)尿道電切綜合征等不足,且其對(duì)高齡或合并其他嚴(yán)重疾病的患者并不合適[4]。經(jīng)尿道980nm激光前列腺汽化術(shù)是治療BPH的新方法,它具有優(yōu)秀的組織消融和止血能力[5]。本研究收集整理了國(guó)內(nèi)外對(duì)上述兩種手術(shù)方式進(jìn)行對(duì)比的相關(guān)臨床研究,并按Cochrane標(biāo)準(zhǔn)進(jìn)行Meta分析,以期為臨床提供參考。

3 討論

BPH是中老年男性常見(jiàn)病,其發(fā)病率隨著年齡的增長(zhǎng)而增加[1],并可能引發(fā)膀胱結(jié)石、泌尿系感染和上尿路積水等癥狀。TURP是目前手術(shù)治療的金標(biāo)準(zhǔn)[2],但它仍有不足,如術(shù)中出血較多,易并發(fā)經(jīng)尿道電切綜合征等,對(duì)于高齡或合并其他嚴(yán)重疾病的患者并不合適[3]。經(jīng)尿道980nm激光前列腺汽化術(shù)是治療BPH的新方法,ROCCO等[4]學(xué)者將其與包括開(kāi)放手術(shù)、TURP、鈥激光前列腺剜除術(shù)(holmium laser enucleation of theprostate,HoLEP)在內(nèi)多種BPH治療手段進(jìn)行初步比較后發(fā)現(xiàn),激光手術(shù)具有手術(shù)學(xué)習(xí)曲線短、術(shù)中術(shù)后出血少、手術(shù)視野清晰、術(shù)后恢復(fù)快和住院時(shí)間短等優(yōu)點(diǎn),但安全性以及中長(zhǎng)期并發(fā)癥等方面尚需更大樣本的觀察及遠(yuǎn)期隨訪。

本研究搜集了國(guó)內(nèi)外對(duì)經(jīng)尿道980nm激光汽化術(shù)與經(jīng)尿道TURP治療良性BPH的療效進(jìn)行比較的文獻(xiàn),最終篩選出6篇文獻(xiàn),并選取住院時(shí)間、手術(shù)時(shí)間、術(shù)后尿管留置時(shí)間、術(shù)后IPSS評(píng)分、術(shù)后QOL評(píng)分及術(shù)后Qmax等6個(gè)指標(biāo)進(jìn)行Meta分析。Meta分析顯示:980nm激光組手術(shù)時(shí)間與TURP組相當(dāng),差異無(wú)統(tǒng)計(jì)學(xué)意義,這說(shuō)明盡管TURP的切割效率略高于980激光組,但需花費(fèi)較多時(shí)間用于止血,而980nm激光由于與水和血紅蛋白有著極好的聯(lián)合吸收特性,使其在保障切割效率的同時(shí)又具有較好的止血功能,從而大大節(jié)約了手術(shù)時(shí)間[9]。另外,F(xiàn)AYAD等[13]研究表明由于粉碎器粉碎前列腺組織占用時(shí)間,導(dǎo)致HoLEP的手術(shù)時(shí)長(zhǎng)明顯高于TURP組,這顯示980nm激光在手術(shù)效率方面的優(yōu)勢(shì)。

而在住院時(shí)間和術(shù)后尿管留置時(shí)間方面980nm激光組上均短于TURP經(jīng)尿道電切組。其原因在于:980nm激光組術(shù)中以生理鹽水代替TURP的甘露醇灌注液,大大降低了TURP綜合征的發(fā)生概率[10]。另外,得益于980nm激光有良好的止血效果,其明顯降低了前列腺術(shù)中術(shù)后的出血。980nm波長(zhǎng)的半導(dǎo)體激光具有水與血紅蛋白的聯(lián)合吸收特性,使得其可在快速切割消融組織過(guò)程中迅速凝血,達(dá)到即刻止血的效果[7,9]。甚至有體外研究顯示,980nm波長(zhǎng)的半導(dǎo)體激光在與鈥激光、綠激光等的對(duì)比中同樣有明顯的止血優(yōu)勢(shì)[14]。

在術(shù)后療效方面,980nm激光組在術(shù)后IPSS評(píng)分、術(shù)后QOL評(píng)分及Qmax方面與TURP組無(wú)明顯差異,均顯示較佳的治療效果。980nm半導(dǎo)體激光在確保切割消融和止血效果的同時(shí),其雙重吸收也使得前列腺的汽化平面更為平整,而且激光光纖的頭端擺動(dòng)來(lái)汽化切割前列腺組織較TURP的近遠(yuǎn)端切割的方式具有更好的操作精準(zhǔn)性和穩(wěn)定性[9]。另有研究表明,980nm波長(zhǎng)的半導(dǎo)體激光治療BPH前后,前列腺特異抗原下降幅度明顯大于TURP組,提示980nm波長(zhǎng)的半導(dǎo)體激光較TURP切除前列腺組織更為徹底,未來(lái)可能取得更好的療效[7]。國(guó)內(nèi)還有學(xué)者利用980nm激光來(lái)治療高危高齡的BPH患者,同樣取得安全滿意的療效[15]。

本Meta分析中納入的部分指標(biāo)異質(zhì)性較高,主要原因是不同國(guó)家和地區(qū)、不同術(shù)者、不同時(shí)間及測(cè)量?jī)x器間的差異等都會(huì)影響統(tǒng)計(jì)指標(biāo)。因此,還應(yīng)進(jìn)行更深入的討論與研究,以使結(jié)果更加準(zhǔn)確可靠。

綜上所述,當(dāng)前證據(jù)表明經(jīng)尿道980nm激光汽化術(shù)與TURP相比,在治療BPH中留置尿管時(shí)間和住院時(shí)間短,在術(shù)后恢復(fù)方面具有一定優(yōu)勢(shì),遠(yuǎn)期效果無(wú)明顯差異。

ObjectiveTo systematically review and evaluate the perioperative indicators and surgical curative effect of 980 nm diode laser vaporization of prostate and transurethral resesction of prostate (TURP) in treating benign prostatic hyperplasia (BPH).MethodsRetrieved published comparative studies 980 nm diode laser vaporization of prostate versus transurethral resesction of prostate in treating benign prostatic hyperplasia, and pooled the data from eligible studies. The statistical analysis was performed using Revman 5.3 software.ResultsSix trials including 839 patients were eligible to the criteria (450 in 980 nm diode laser group and 389 in TURP group). The baseline of patients characteristics were comparable in all the studies. Meta analysis showed that: the operative time was not significantly different between the 980 nm diode laser group and TURP group [SMD = 0.11, 95 ~ CI (-0.52,0.74), P > 0.05]; Compared with TURP group, 980 nm diode laser group has shorter hospital stays [SMD = -1.95,95%CI (-3.42, -0.48), P < 0.05], and shorter catheterization time [SMD = -2.64, 95%CI (-3.92, -1.36), P < 0.05].There was no significant difference between IPSS [WMD = 0.12, 95%CI (-0.27, 0.51), P > 0.05], QOL [SMD = 0.00,95%CI (-0.57, 0.57), P > 0.05] and Qmax[SMD = 0.06, 95%CI (-0.26, 0.37), P > 0.05].Conclusion980 nm diode laser vaporization of prostate is safe and effective in treating benign prostatic hyperplasia, and compared with TURP,it has advantages in shorter hospital stays and shorter catheterization time.
