[How good are we really? Incidence of postoperative bleeding requiring intervention and intraoperative electrocoagulation during Thulium laser enucleation of the prostate].

The need for intervention due to postoperative bleeding represents a significant complication in Thulium Laser Enucleation of the Prostate (ThuLEP). This study aimed to retrospectively analyse this complication in the treatment of benign prostatic enlargement. This study focuses on investigating potential causative factors for postoperative bleeding requiring intervention as well as the use of intraoperative electrocoagulation.

[Thulium or holmium laser or both: where will the journey take us?].

The Holmium:YAG laser has been the gold standard for laser lithotripsy over the past three decades and, since the late 1990s, also for prostate enucleation. Pulsed thulium fibre lasers (TFL) demonstrated their efficacy in in-vitro experiments and were introduced to the market a few years ago. Initial clinical results for TFL in lithotripsy and enucleation are very promising.
