Abstract:
The Gyrus system uses bipolar electrocautery with saline irrigation to vaporize prostatic tissue and is compared to transurethral resection of the prostate (TURP) in a randomized prospective study with 1 y follow-up. Outcomes measured were fluid absorption, blood loss, period of catheterization, hospital stay, symptom scores, quality of life, flow rates, and post-void residual volumes at 3, 6, and 12 months. All measured parameters were similar, although re-catheterization rates were higher (30% vs 5%) in the Gyrus group. Clot evacuation rates were higher in the TURP group (19% vs 0%). The Gyrus device is safe and produces results that are similar to TURP at 1 y.
