Efficacy and safety of prostate vaporesection using a 120-W 2-μm continuous-wave Tm:YAG laser (RevoLix 2) in patients on continuous oral anticoagulant or antiplatelet therapy

摘要

The aim of our current study was to demonstrate the efficacy and safety of vaporesection using a 120-W Tm:YAG laser (Revolix Duo) in patients with BPH receiving systemic anticoagulation or antiplatelet therapy. Between April 2010 and November 2011, a total of 76 patients using oral antiplatelet or anticoagulant (OA) agents affected by LUTS for BPH were underwent thulium vaporesection of the prostate (ThuVARP) using a 120-W 2-μm CW Tm:YAG laser and evaluated at 3- and 6-month follow-up. Of these, in 41 patients (group A) was performed vaporesection while receiving OA therapy. In 35 patients (group B), OA agents were discontinued 10 days before surgery. There were no significant differences in average vaporesection times, catheterization time, or hospital stay. There was no significant change in serum sodium level before and immediately after vaporesection in either group. Significant improvements compared to baseline were observed at each postoperative assessment in both groups for Qmax, PVR, IPSS, and QoL. More specifically, the IPSS score improved from 21.7 at baseline to 5.2 at 6 months in group A and from 20.7 to 4.5 in group B. At 6 months, Qmax increased 226 and 190 % for the 2 groups, respectively. The PVR decreased from 119 at baseline to 11 mL at 6 months in group A and from 125 to 11 mL in group B. ThuVARP is a safe and efficient procedure for patients with BPH, refractory to pharmacotherapy, who require active antiplatelet or anticoagulant therapy.
