Fagerström T, Nyman CR & Hahn RG. “Complications and clinical outcome 18 months after bipolar and monopolar transurethral resection of the prostate.” BJU International. June 2010, Volume 105, Issue 11: pages 1560–1564. 

OBJECTIVE: To compare bipolar resection with the conventional monopolar transurethral resection of the prostate (TURP) with respect to peri- and postoperative complications and long-term outcome.

RESULTS: Bipolar surgery was followed by a 16% to 20% higher percentage of the patients reporting ongoing improvement (fractional IPSS change >2) at 3 and 6 weeks after the surgery (p<0.05). There were fewer readmissions in the bipolar group than in the monopolar (5 vs. 13, p<0.05). No differences between the groups with respect to hospital stay and catheter duration was recorded. Bipolar and monopolar TURP resulted in marked and sustained improvements of IPSS, bother score, and TM.

CONCLUSIONS: Bipolar TURP, using the transurethral resection in saline (TURis) system, resulted in significantly fewer postoperative readmissions, faster postoperative recovery, and equally long-lasting good results in TM/IPSS and bother score, as in monopolar TURP.
