All procedures were performed by a single experienced surgeon (Tokatli
Z.) who had carried out more than 300 HoLEP procedures for various sized
prostates .HoLEP was performed with our previously described technique
(low tension total retrograde HoLEP technique), as two or three lobes
technique depending on prostate morphology (with/without huge median
lob).11A 26-Fr continuous-flow laser resectoscope (Karl- Storz, Germany) in
combination with a mechanical tissue morcellator (Versacut; Lumenis Inc)
was used for both groups. In group 1, HoLEP procedures were performed by
using 50W holmium laser device (Auriga® XL, Boston Scientific, Ratingen,
Germany) at 39.6W (2.2 Joule, 18 Hz). In group 2, a 100W Holmium laser
(Versapulse, Lumenis Inc., Santa Clara, CA, USA) was used at 42-W (1.2J
and 35Hz), comparable with the 50W device.
