Abstract

Five α-reductase inhibitors (5ARIs) are able to reduce prostate volume and are a useful treatment for reducing perioperative bleeding during prostate surgery. Holmium laser enucleation of the prostate (HoLEP) is an effective surgical technique for the definitive cure of benign prostate enlargement.

We investigated whether pretreatment with dutasteride before HoLEP could reduce intraoperative bleeding. A total of 402 patients were included in this double-blind placebo-controlled trial to receive daily 0.5 mg of dutasteride or placebo over 8 weeks before HoLEP. Vascular endothelial growth factor (VEGF) and microvascular density (MVD) were evaluated. Analysis was also stratified according to prostate volume (<70 mL vs ≥70 mL).

Hemoglobin and hematocrit values before and after surgery were not statistically different between the two groups. MVD and VEGF index in smaller prostates were 23.35±1.96 and 4.06±0.76 in the treatment group and 19.04±0.96 and 2.55±0.55 in placebo (p<0.05); in patients with larger prostates MVD and VEGF were 26.83±2.812 and 8.54±1.18 in the treatment group and 20.76±0.79 and 3.21±0.54 in placebo (p<0.05).

Vascularization of the prostate was affected by 5ARIs therapy. HoLEP is less burdened in perioperative bleeding and for this reason we did not find any difference in hemoglobin/hematocrit values pre- and post- surgery.
