Purpose: To evaluate the feasibility and safety of thulium:yttrium-aluminium-garnet laser vapoenucleation of the prostate (ThuVEP) in patients with chronic anticoagulation and bleeding disorders. Methods: We retrospectively analyzed the clinical data (transfusion rate, hemoglobin changes, residual urine, bleeding complications, complications and residual urine) of patients with chronic anticoagulation and bleeding disorders treated with ThuVEP. Anticoagulation was not paused for surgery. Results: We identified 39 patients who fulfilled the inclusion criteria (32 with chronic anticoagulation, 3 with bleeding disorder, and 4 with both). Mean preoperative hemoglobin was 12.9 g/l; the postoperative hemoglobin was 11.7 g/l. One patient received a blood transfusion. Mean residual urine was 166 ml preoperatively and 47 ml postoperatively, respectively; spontaneous voiding postoperatively was feasible in 36 patients. During follow-up, 5 patients suffered from gross hematuria, which was treated conservatively. Conclusions: ThuVEP is a safe procedure in patients with therapeutic anticoagulation, bleeding disorders and platelet aggregation inhibitor medication.
