INTRODUCTION The BPH surgical armamentarium is composed of a rapidly expanding number of technologies and techniques. These include greenlight photovaporization of the prostate (PVP), greenlight enucleation of the prostate (GreenLEP), holmium laser enucleation of the prostate (HoLEP), thulium laser enucleation of the prostate (ThuLEP) and, more recently, the aquablation procedure. To the best of our knowledge, no direct comparison in operative time has been performed. METHODS Data for this study were pooled from five sources. For aquablation, patient-level data from four studies of the aquablation procedure were provided by the device manufacturer as well as from a high-volume commercial user. PVP, GreenLEP, HoLEP, and ThuLEP were performed by high-volume, experienced experts. Endpoints included total operative time, resection time, and proportion of total operative time for resection. General linear models were used to evaluate the relationship between prostate volume (or other continuous predictors) and procedure time. RESULTS Total procedure time was related to prostate size. Except for the small prostate size range (size < 40 cc), at any given prostate volume, procedure time was highest for PVP, intermediate for LEPs, and lowest for Aquablation. The relationship between procedure time and prostate size (i.e., slope of the fitted lines) was 0.16 min/g for aquablation, 0.32 min/g, 0.28 min/g and 0.32 min/g for GreenLEP, HoLEP and ThuLEP, respectively, and 0.63 min/g for PVP. CONCLUSION In our analysis of pooled data of multi-surgical techniques and technologies, aquablation provided the lowest operative time across all prostate volumes. PVP had the longest procedure time for prostates > 40 cc.

aquabation，greenlight PVP，ThuLEP，GreenLEP和HoLEP的手术时间比较。

简介BPH外科手术设备由迅速扩展的技术组成。这些包括前列腺的绿光光汽化（PVP），前列腺的绿光摘除（GreenLEP），前列腺的laser激光摘除（HoLEP），前列腺的laser激光摘除（ThuLEP），以及最近的消融术。据我们所知，尚未进行手术时间的直接比较。方法本研究的数据来自五个来源。对于无水化，设备制造商以及大量商业用户从四项无水化程序研究中获得了患者水平的数据。PVP，GreenLEP，HoLEP和ThuLEP由大量经验丰富的专家执行。终点包括总手术时间，切除时间，和手术总时间的比例。一般线性模型用于评估前列腺体积（或其他连续预测指标）与手术时间之间的关系。结果总手术时间与前列腺大小有关。除了较小的前列腺尺寸范围（尺寸<40 cc），在任何给定的前列腺体积下，PVP的手术时间最高，LEP的手术时间最长，而Aquablation的手术时间最低。手术时间与前列腺大小（即，拟合线的斜率）之间的关系对于aquablation分别为0.16 min / g，对于GreenLEP，HoLEP和ThuLEP分别为0.32 min / g，0.28 min / g和0.32 min / g，以及0.63 PVP的最小/克。结论在我们对多手术技术的汇总数据的分析中，全前列腺切除术在所有前列腺体积中的手术时间最短。
