Does the power of the laser devices matter for a successful HoLEP
procedure? A prospective comparative study
Background: 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.
