title: [Bipolar versus monopolar transurethral resection of the prostate: peroperative analysis of the results].
abstract: OBJECTIVE
  To analyse the differences in the postoperative period between bipolar and monopolar resection of the prostate in the endoscopic surgery of the benign prostatic hyperplasia.
  
  
  METHODS
  45 patients were prospectively randomized. Twenty-one underwent monopolar resection (Storz Ch 26, 30 degrees) and 24 underwent bipolar resection (Olympus ch 26, 30 degrees).
  
  
  RESULTS
  Mean age in the bipolar group was 69,5 years versus 67,3 in the monopolar group; mean flow before surgery (7,7 ml/s vs 7,2 ml/s); ecographic prostate volume (39,5 cc vs 42,7 cc); resection volume 13 g vs 12,6 g and mean resection time was 39,7 vs 42,5 min. Cut capacity was considered notable-excellent in 90% of the patients in the bipolar group vs 50% in the monopolar group (p=0,01); adherence of fragments were considered abundant or very abundant in 0% vs 60% (p=0,01); coagulation capacity was excellent-notable in 25% vs 75% (p=0,03). There were no significant differences on the days of catheterization (2,92 vs 3,1), continuous irrigation (1,79 vs 2,05), hospitalization (3,63 vs 3,67), hematocrite descent (3,48 vs 3,32) and plasmatic sodium (0,52 vs 1,16), neither on episodes of acute urine retention (only one patient in the monopolar group).
  
  
  CONCLUSIONS
  In our experience, TURP with SurgMaster resector in prostate smaller than 70 g offers better peroperative qualities for the surgeon (better cut capacity, less adherence of fragments) than the monopolar resection, with similar postoperative outcomes.
