“…The surgical management of BPO is complicated by an increasing use of oral anticoagulants (OA) for primary and secondary prevention of cardiovascular complications [2]. However, a controversy exists regarding the performance of TURP under OA: while transfusion rates up to 28.6% have been found in older series [3,4,5], these transfusion rates could not be confirmed in more recent studies with transfusion rates up to 11% [6,7,8]. Various, more minimally invasive laser devices have been introduced as alternatives to TURP for the surgical treatment of BPO during the past 20 years [9,10]: the potassium-titanyl-phosphate (KTP) [2,11,12,13,14,15,16], the holmium:YAG [17,18], and the thulium:YAG [19,20,21] laser.…”
