Background and Purpose: Photoselective laser vaporization prostatectomy (PVP) with a high-power KTP laser is a hemostatic procedure for men with symptomatic benign prostatic hyperplasia (BPH). This study demonstrates the feasibility of PVP in men who are receiving anticoagulants. Patients and Methods: Men treated with PVP for symptomatic BPH between July 2002 and September 2003 who were receiving anticoagulants (N = 24) were reviewed retrospectively. Their mean age was 75 years, and the mean prostate volume was 82 cc (range 34-164 cc). Nine men (38%) were in retention, eight (33%) had had a myocardial infarction, seven (29%) had had a cerebrovascular accident, and seven had peripheral vascular disease. Of these men, 8 were on warfarin, 2 on clopidogrel, and 14 on aspirin. Men on warfarin discontinued the drug 2 days prior to surgery and restarted it the day after. The other two drugs were not discontinued. The PVP was performed with an 80 W KTP side-firing laser (Laserscope Greenlight PV) through a 23F continuous-flow cystoscope with normal saline as the irrigant. Results: The mean operative time was 101 minutes. No transfusions were required. Most (22; 92%) of the men were discharged without a catheter. The serum hematocrit did not change significantly (40.0% to 38.3%). The International Prostate Symptom Score decreased to 13.6, 10.9, 9.7, and 9.5 at 1, 3, 6, and 12 months from a mean of 18.7 preoperatively. The Q max increased from 9.0 mL/sec preoperatively to 15.1, 16.3, 20.9, and 20.1 mL/sec at 1, 3, 6, and 12 months. No patients had clinically significant hematuria postoperatively, and none suffered clot retention. Conclusions: Photoselective laser vaporization prostatectomy is a suitable treatment option in men being treated with anticoagulants, who are at high risk for clinically significant bleeding.
