Abstract
Purpose To compare the perioperative and functional outcomes between 180_W XPS GreenLight photoselective vaporization (PVP) and 532-nm GreenLight laser enucleation of the prostate (GreenLEP) in the surgical management of benign prostatic obstruction (BPO). Methods Retrospective review of a prospectively maintained international database of patients managed with GreenLight laser surgery (PVP or GreenLEP) was performed. To adjust for potential baseline confounders, propensity-score matching (PSM) was applied at a ratio of 1:1 to compare the perioperative and functional outcomes between the groups. Results A total of 2,420 patients were included. 1,491 (61.6%) underwent PVP and 929 (38.4%) underwent GreenLEP. Before PSM analysis, patients in the vaporization group were older (p < 0.001), had a lower PSA and prostate volume at baseline (p < 0.001). Using estimated propensity scores, 78 patients in the PVP group were matched 1:1 to the patients in the GreenLEP group. The incidence of overall postoperative complications was comparable between the two groups (19 vs. 16%, p = 0.06). However, after PSM, PVP was found to be associated with a higher rate of overall complications (33 vs. 11%, p = 0.001). At 3 months and at last follow-up the I-PSS, Qmax and PSA had similarly decreased in the two groups with a greater improvement in the GreenLEP group (all p < 0.05). Conclusions PVP and GreenLEP are two efficient and safe techniques for treating BPO. However, PVP was associated with longer operative time and higher risk of reoperation on a midterm follow-up compared to GreenLEP.This publication has 26 references indexed in Scilit:
