AB074. 180-W XPS GreenLight laser vaporization versus transurethral resection of the prostate for the treatment of benign prostatic hyperplasia: 2 months safety and efficacy results of Korean

Objective: To compare short-term outcomes of 180W-XPS GreenLight photoselective vaporization of the prostate (XPS PVP) to transurethral resection of prostate (TURP) on uroflowmetry and IPSS at two months in patients with benign prostatic hyperplasia (BPH)

Methods: A retrospective chart review was performed of 40 patients with BPH who underwent XPS PVP. Controls were configured with 40 patients who underwent TURP with similar prostate size of XPS PVP group. All parameters were collected retrospectively including maximum urinary flow rate (Qmax), postvoid residual (PVR), prostate specific antigen, IPSS, and complication.

Results: XPS PVP and TURP were similar in preoperative parameters such as mean age, prostate volume, Qmax, PVR, IPSS and QoL score respectively. The median operative time for XPS PVP was significantly longer than TURP (49.1±19.5 min TURP and 69.9±38.6 min XPS PVP, P=0.001). XPS PVP showed significantly shorter hospital stay (4.5±1.0 vs. 3.0±1.4, P<0.001). Postoperative Qmax, PVR, IPSS all improved compared to baseline at two months of follow-up in XPS PVP. There was no statistically significant difference between XPS PVP and TURP for each of these parameters. No patient needed transfusion and re-operation in XPS PVP and two patients had re-operation in TURP.

Conclusions: PVP treatment using XPS-180 is safe and effective procedure for treating BPH comparing TURP.
