INTRODUCTION: To evaluate the short-term results of thulium vaporesection of the prostate (ThuVEP) and thulium vapoenucleation of the prostate (ThuVARP) in patients with benign prostatic obstruction on oral anticoagulants (OA). METHODS: A 3-centre retrospective matched-paired comparison of patients treated by ThuVEP (n = 26) or ThuVARP (n = 26) was performed. Thirty-four patients were on aspirin/ticlopidin, 7 on clopidogrel or clopidogrel and aspirin, and 11 on phenprocoumon at the time of surgery. RESULTS: Haemoglobin decrease was higher after ThuVEP compared to ThuVARP (1.5 vs. 0.3 g/dl, p < 0.001). The rate of postoperative blood transfusions (3.9 vs. 0%), clot retention (3.9 vs. 0%), and re-operation (7.7 vs. 0%) was not different between ThuVEP and ThuVARP (p = 0.274). Catheterization time was shorter for ThuVARP (1 vs. 2 days, p < 0.01). Qmax was significantly higher after ThuVEP at 6-month follow-up (31 vs. 21.5 ml/s, p < 0.001), while improvements in International Prostate Symptom Score, quality of life, and post-voiding residual urine showed no differences between the groups. Urethral or bladder neck strictures did not occur during the 6-month follow-up in both groups. CONCLUSIONS: ThuVEP and ThuVARP are safe and efficacious procedures in patients on OA. Although patients assigned to ThuVEP had higher Qmax at 6-month follow-up, ThuVARP resulted in similar functional outcomes.
