[Bipolar versus monopolar transurethral resection of the prostate: a prospective randomized study].
OBJECTIVE
To compare bipolar with standard monopolar transurethral resection of the prostate (TURP).


METHODS
A prospectively randomized study was conducted between January 2010 and September 2011. Primary end points studied were efficacy (maximum flow rate [Qmax], International Prostate Symptom Score) and safety (adverse events, decline in postoperative serum sodium [Na+] and haemoglobin [Hb] levels). Secondary end points were operation time and duration of irrigation, catheterization, and hospitalization.


RESULTS
Sixty consecutive patients were randomized and completed the study, with 29 patients in the monopolar TURP group and 31 in the TURIS group. At baseline, the two groups were comparable in age, prostate volume, mean prostate-specific antigen value, International Prostate Symptom Score, and they had at least 12 months of follow-up. Declines in the mean postoperative serum Na+ for bipolar and monopolar TURP groups were 1.2 and 8.7 mmol/L, respectively. However, there was no statistical difference in the decline in postoperative Hb between the two groups. The mean catheterization time was 26.6 and 52 hours in the bipolar and standard groups, respectively. This difference was statistically significant as was the difference in the time to hospital discharge. The IPSS and Qmax improvements were comparable between the two groups at 12 months of follow-up.


CONCLUSIONS
No clinically relevant differences in short-term efficacy are existed between the two techniques, but bipolar TURP is preferable due to a more favorable safety profile and shorter catheterization duration.
