Comparison of GreenLight 180-W XPS laser vaporization versus transurethral resection of the prostate: Outcomes of a single regional center

摘要

Background: To evaluate the intermediate perioperative outcomes, rate of complications and functional data after XPS 180-W Greenlight photoselective laser vaporization (PVP) compared with transurethral resection of the prostate (TURP) in a prospective non-randomized single centre study. Methods: We analyzed a prospectively-maintained database collecting data on 100 patients undergoing surgical treatment of BPH (50 consecutive PVP and 50 consecutive TURP). All complications, recorded and graduated according to the Clavien Dindo system and the clinical, operative, perioperative variables were compared. The functional outcomes, International Prostate Symptom Score (IPSS), max flow rate (Qmax) and Prostate Specific Antigen (PSA), were recorded preoperatively and at 1 year of follow up. Results: Age, prostate volume, use of anticoagulants or antiplatelets, ASA score and operative time were comparable in the two groups. The reduction in the hemoglobin levels (0.46 vs 1.8 g/dL), the catheterization time (1.2 vs 3.2 days), the hospital stay (1.7 vs 3.8 days) and rate of transfused patients (0 vs 8%), were significantly lower for PVP. Transient re-catherization (6 vs 26%) was significantly lower for PVP. The IPSS and Qmax at 1 year showed no significant difference. The rate of repeat TURP/PVP was higher in the TURP group (0 vs 10%). Reduction of PSA, that reflects the major reduction of prostate volume, was statistically greater in PVP group respect TURP group (p = 0.001). Conclusions: PVP has advantages in terms of perioperative safety and major complications than TURP. Functional outcomes at 1 year of follow-up were comparable.
