The Comparison Study of Anatomic Vapor-incision Technique (AVIT) Using the 180W-XPS Greenlight Laser and Photoselective Vaporization of the Prostate for the Treatment of Benign Prostatic Hyperplasia

Abstract

ObjectiveTo prospective compared the preoperative parameters and postoperative functional outcomes between anatomic vapor-incision technique (AVIT) and the photoselective vaporization of prostate (PVP) with Greenlight 180W-XPS. MethodsTotal 174 BPH patients were enrolled in the study and 86 cases, 88 cases were underwent with traditional PVP and AVIT, respectively. The relevant pre-, intra-, and postoperative data were recorded and compared between the both groups. ResultsNo significant differences were observed between both groups in baseline characteristics and no major complications (capsule perforation and TUR syndrome) occurred intraoperatively. In AVIT group, the energy consumption and energy density were greater than those in PVP group. The operative time and laser time were longer in AVIT group than it in PVP group. Compared to the AVIT group, the incidence of irritative symptoms after operation was higher in the PVP group. During the follow-up period, the functional outcomes (IPSS, QoL, prostate volume and PSA level) in both groups were significant improved compared to the baseline. The reduction of prostate volume and PSA level were significant greater in AVIT group than it in PVP group. ConclusionCompared to PVP, AVIT is safe and efficacious treatment for BPH patients with more adenoma removal and more improvements of clinical outcomes. But the long-term follow-up data is needed to evaluate the functional outcomes and retreatment rates.
