Randomized Controlled Trial Comparative Study Clinical TrialTransurethral electrovaporization of the prostate: is it any better than standard transurethral prostatectomy? 5-year follow-up.
At present, transurethral resection of the prostate (TURP) is regarded as the most effective treatment for benign prostate hyperplasia (BPH). In the present randomized study, we compared TURP with transurethral electrovaporization of the prostate (TUVP). ⋯ The TUVP procedure is as effective as TURP with similar morbidity. The advantages of TUVP are that the urethral catheter is withdrawn earlier, hospitalization is shorter, and bleeding is less. Its disadvantage is that tissue cannot be sampled for histologic diagnosis. In our opinion, in order to exploit the advantages of this technique, TUVP should be preferred in elderly patients without any suspicion of prostate cancer for whom bleeding during operation is a source of risk.

Comparative StudyPlasmaKinetic bipolar vessel sealing: burst pressures and thermal spread in an animal model.
Laparoscopic bipolar instruments are commonly employed to cauterize and divide tissue. A next-generation bipolar device has been developed that employs vapor pulse coagulation energy. We assessed the vessel-sealing capability of this device and quantified thermal spread during application. ⋯ The Gyrus PlasmaKinetic bipolar device is capable of reliably sealing/ dividing arteries as large as 6 mm, although we recommend restricting its use to vessels no larger than 5 mm in diameter to allow a safety margin. In addition, porcine renal veins of all sizes are adequately controlled. These sealed vessels are able to withstand pressures approaching 300 mm Hg. Thermal spread affects only the area surrounding the divided vessel. Further clinical studies are warranted.
