目的比较钬激光剜除术(HoLEP)与铥激光剜除术(ThULEP)治疗良性前列腺增生的疗效及安全性。方法检索PubMed、EMbase、The Cochrane Library、Web of Science、中国知网、万方数据库、维普数据库,收集HoLEP与ThULEP治疗良性前列腺增生的...目的比较钬激光剜除术(HoLEP)与铥激光剜除术(ThULEP)治疗良性前列腺增生的疗效及安全性。方法检索PubMed、EMbase、The Cochrane Library、Web of Science、中国知网、万方数据库、维普数据库,收集HoLEP与ThULEP治疗良性前列腺增生的临床研究,检索时间为建库至2024年4月。采用Cochrane偏倚风险评估工具对纳入文献进行方法学质量评价,利用RevMan 5.4.1软件对纳入数据进行统计学分析。结果共纳入11篇文献,涉及良性前列腺增生患者2029例。meta分析结果显示,HoLEP与ThULEP患者残余尿量(PVR)、国际前列腺症状评分(IPSS)、生活质量评分(QOL)、最大尿流率(Qmax)、前列腺特异性抗原(PSA)、并发症发生率、手术时间及拔管时间比较,差异均无统计学意义(均P>0.05)。HoLEP患者剜除时间长于ThULEP患者,术中出血量多于ThULEP患者(均P<0.05),且各研究间患者术后PVR、IPSS、QOL、Qmax、PSA、并发症发生率、剜除时间及拔管时间无异质性(I^(2)=0%~46%),手术时间存在异质性(I^(2)=92%)。结论HoLEP与ThULEP治疗良性前列腺增生的效果及安全性相似,但相比HoLEP,ThULEP的剜除时间更短,术中出血量更少。展开更多

The effect of new surgical procedures, which are currently available to treat BPH, on erection and ejaculation, has been poorly studied. This study aimed to assess the effect of thulium laser enucleation of the prostate （ThuLEP） on sexual function and retrograde ejaculation in patients with LUTS secondary to BPH. We performed a prospective study in 110 consecutive patients who had undergone ThuLEP to analyze changes in sexual function and urinary symptoms. To evaluate changes in erection and ejaculation, and the effect of urinary symptoms on the quality of life （QoL）, five validated questionnaires were used： the ICIQ-MLUTSsex, MSHQ-EjD, International Index of Erectile Function 5, International Prognostic Scoring System （IPSS） questionnaire, and QoL index of the intraclass correlation coefficients. Patients also underwent IPSS and flowmetry to assess the outcome of flow. Patients were evaluated before surgery and 3-6 months after ThuLEP, whereas those with previous abdominal surgery were excluded. The patients＇ mean age was 67.83 years. Postoperative urinary symptoms improved after surgery. No significant differences in erectile function before and after surgery were observed. As compared with other techniques described in the literature, the percentage of patients with conserved ejaculation increased by 52.7% after ThuLEP. ThuLEP positively affects urinary symptoms and their effect on the QoL of patients as assessed by questionnaire scores. While endoscopic management of BPH （e.g. transurethral resection of the prostate） causes retrograde ejaculation in most patients, those who undergo ThuLEP have conserved ejaculation and erectile function.展开更多
