Resumen:
Objective: To compare the results of efficacy and safety of Thulium
laser 150 W against Green light laser 120W in the treatment of short
term benign prostatic hyperplasia (12 months after surgery).
Material and methods: This is a retrospective observational study where
men who underwent the surgical technique of prostate vaporization over a
period of four years in our center are included. The homogeneity of the
sample was checked, and postoperative complications (acute urinary
retention, reentry, need for transfusion), failures per year of surgery
(reoperation, peak flow < 15 ml/sec, no improvement in comparing the
I-PSS), and decreased PSA were compared a year after surgery. A
bivariate analysis using Chi-square and t-Student was carried out.
Results: 116 patients were treated with thulium and 118 with green
laser. The sample was homogeneous for preoperative variables (P> .05).
No differences in complications were observed: in urine acute retention,
4.3% with thulium and 6.8% with green laser (P= .41); in readmissions,
2.6% with thulium and 1.7% with green laser (P= .68); in need for
transfusion, 2.6% with thulium and 0% with green laser (P= .12). No
differences were observed in the percentage of patients reoperation
(1.7% in the group of thulium, 5.1% in the green laser, P= .28); or in
individuals with Qmax less than 15 ml/sec (6.9% with thulium, 6.77% with
green laser, P= .75), or in the absence of improvement in the IPSS (5,
2% with thulium, 3.4% with green laser, P= .65). There was also no
difference in the levels of PSA in ng/mL a year after surgery: with
thulium 2.78 +/- 2.09 and with green laser 1.83 +/- 1.48 (P= .75).
Conclusions: Prostate vaporization with thulium laser 150 W is
comparable to that made with green laser 120 W for the treatment of
lower urinary tract symptoms caused by BPH, being both effective and
safe techniques to 12 months after surgery. Future prospective
randomized studies are needed to confirm this conclusion on both
techniques. (C) 2016 AEU. Published by Elsevier Espana, S.L.U. All
