Introduction: Comparative analysis of transurethral prostate resection with bipolar technology, between the Mauermayer technique and the proposed modification. Objective: Board the gland between the capsule and the adenoma, as does the enucleation technique. Method: Analytical cross-sectional study in 132 patients undergoing transurethral resection of the prostate with bipolar technology, divided into group I: 55 patients operated with the Mauermayer technique and group II: 77 patients operated with the modified technique. We describe both techniques and analyze the variables before and after the surgical procedure in both groups. Results: In both groups, there was significant improvement, when comparing the efficiency variables, before and after surgery: International Prostate Symptom Scale, maximum urinary flow, average urinary flow, prostate-specific antigen level and post-micturition residual urine, without significant difference between both groups. The average surgical time was 81 minutes in group I and 71 minutes in group II (p = 0.04), and the amount of tissue removed was 42g (1g/1.9 minutes) for group I and 46g (1g/1.5 minutes) for group II (p = 0.14). The average intraoperative bleeding was 272 mL in group I and 235 mL in group II (p = 0.25). 4 patients in group I and 3 patients in group II were transfused. Conclusion: The modification to the Mauermayer technique proved to be efficient, well systematized; we removed a greater amount of tissue, with less bleeding, although only the shorter surgical time was statistically significant.
