Bipolar transurethral resection of the prostate causes less bleeding than the monopolar technique : a single-centre randomized trial of 202 patients . OBJECTIVE To compare bipolar with the conventional monopolar transurethral resection of the prostate ( TURP ) for blood loss and speed of resection . PATIENTS AND METHODS In all , 202 consecutive patients from the hospital waiting list were randomized to undergo TURP using either a bipolar system ( Surgmaster TURis , Olympus , Tokyo , Japan ) or a monopolar system ( 24 F , Storz , Tübingen , Germany ) . The blood loss during and after surgery was measured using a photometer . Other variables compared included indices of resection speed and transfusion rate . RESULTS There were no statistically significant differences in operative duration , resection weight , resection speed or radicality of resection . However , the median blood loss was 235 mL for the bipolar and 350 mL for monopolar TURP ( P < 0.001 ) . The decrease in blood haemoglobin concentration during the day of surgery was smaller in the bipolar group ( 5.5 % vs 9.6 % P < 0.001 ) . Fewer patients were transfused with erythrocytes ( 4 % vs 11 % , P < 0.01 ) , which can be explained by the much lower 75th percentile for blood loss in the bipolar group ( at 472 vs 855 mL , respectively ) . CONCLUSIONS Bipolar TURP using the TURis system was performed with the same speed as monopolar TURP but caused 34 % less bleeding , the difference being greatest ( 81 % ) for the largest blood losses . Bipolar TURP also required fewer erythrocyte transfusions than the conventional monopolar technique .
