A Prospective Study of Bipolar Transurethral Resection of Prostate Comparing the Efficiency and Safety of the Method in Large and Small Adenomas

Abstract EN

Bipolar technology offers a new perspective in the treatment of BPH.

Purpose.

To present our experience with the TURis system (Olympus, Tokyo, Japan).

Materials and Methods.

From February 2011 till December 2013 in a prospective study, 93 patients were treated for BPH.

They were evaluated with IPSS, QoL, uroflow ( Q max ), and residual urine (RU), preoperatively as well as 6 and 9 months postoperatively.

Based on the prostate volume, the patients were divided into two groups: group A ( n = 48 ) with prostates ≥ 75 cc and group B ( n = 45 ) with smaller prostate glands.

All patients underwent bipolar TURP or/and plasma vaporization.

Results.

The postoperative improvement for IPSS, QoL, Q max , and RU was statistically significant.

The operation time was longer in group A in comparison with group B ( P < 0.001 ).

The former group also had higher infection and stricture formation rates; however, there was no statistical difference between the two groups.

Conclusions.

Treatment with the TURis constitutes an effective technique and can be offered to large prostates with results equivalent to those in small ones.

Regarding safety, large adenomas treated with TURis are not at a higher risk for urethral stricture but their odds to develop urogenital infections are relatively higher compared to the smaller adenomas.
