Operative time comparison of aquablation, greenlight PVP, ThuLEP, GreenLEP, and HoLEP

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. 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. Total procedure time was related to prostate size. Except for the small prostate size range (size 40 cc.
