Transurethral resection of prostate: technical progress and clinical experience using the bipolar Gyrus plasmakinetic tissue management system.
BACKGROUND
The efficacy and safety of a new transurethral endoscopic device using bipolar electrocautery, the Gyrus system, were evaluated. This system permits rapid prostate tissue removal by endoscopic vaporization with little bleeding using saline irrigation, therefore eliminating transurethral resection of the prostate (TURP) syndrome.


METHODS
Between January 2000 and December 2006 a total of 401 patients with benign prostatic hyperplasia underwent transurethral resection of the prostate utilizing the Gyrus device.


RESULTS
We did not observe intraoperative complications, secondary hemorrhage with postoperatively severe fall of haemoglobin or any differences in sodium concentrations. Mean peak flow rate increased from 8.5 preoperatively to 24.5 ml/s at 36 months and mean International Prostatic Symptom Score (IPSS) decreased from 18 preoperatively to 5 at 36 months.


CONCLUSIONS
Our preliminary results with a bipolar electrode for electrovaporization of the prostate using the Gyrus suggest that it is a useful and safe endoscopic device.
