ABSTRACTBackground: To evaluate the efficiency and safety of medium
power (MP) holmium laser devices in the enucleation of the enlarged
prostate (HoLEP) adenomas compared to high power (HP) laser devices.Methods: Based on the device power used, a total of 120
patients were divided randomly into two groups. While patients in Group
1 were treated with a MP device (50 W) at 39.6-W (2.2J / 18Hz ),
patients in Group 2 were treated with HP (100W) device at 42W (1.2J /
35Hz). Peri- and postoperative parameters were well evaluated in both
groups with an emphasis on enucleation efficiency and hemoglobin
decrease in a comparative manner.Results: Peri- and postoperative parameters as well as
functional results were similar in the two groups. The median
enucleation efficiency (EE) values in Group 1 and Group 2 were 1.15
(IQR: 0.33-2.2) and 1.11 (IQR: 0.4-2.8), respectively (p=0.775).
Hemoglobin decrease values in Group 1 and Group 2 were 1.3 (IQR: 0.1-4)
and 1.4 (IQR: 0.4-3.1), respectively (p=0.736). Significant improve in
the postoperative functional parameters were noted again in both groups.Conclusion: Our results indicate well that similar to the HP
laser devices, effective and safe removal of the enlarged prostate
adenomas with MP laser devices (50W) is possible without any technical
difficulties, even in patients receiving antithrombotic therapy.Keywords: benign prostatic hyperplasia, high power laser

(HP-HoLEP) devices for more effective and safe results is controversial.
