Clinical Outcomes of Transurethral Enucleation with Bipolar for Benign Prostatic Hypertrophy

This study compared outcomes of transurethral enucleation with bipolar (TUEB) with transurethral resection in saline (TURis).

Thirty patients who underwent TURis were compared with 30 who underwent TUEB. Perioperative treatment outcomes, preoperative and 1-month postoperative International Prostrate Symptom Scores (IPSS), quality of life (QOL) index, maximum flow rate, average urinary flow, post- void residual urinary volume, and complications were compared.

There were no significant differences in IPSS, measurements of urinary flow, or duration of catheterization. However, the improvement of QOL index after surgery was significantly greater in the TUEB group than the TURis group. The TUEB group had significantly longer surgical time, but tended to have greater enucleated tissue weight than the TURis group. There was no significant difference in enucleated tissue weight per unit time between the groups. The TUEB group also tended to have less hemoglobin decrease at postoperative day 1; this tendency was more prominent in patients with an estimated prostate volume of ≥ 50 ml. No significant differences in postoperative complications were observed.

This study confirmed that the previously reported safety and efficacy of TUEB are comparable to those of TURis. TUEB appears especially safe for those with a large benign hypertrophic prostate.
