Early postoperative outcome of bipolar transurethral enucleation and resection of the prostate

Abstract

Objectives: To report the early postoperative outcome of bipolar transurethral enucleation and resection of the prostate. Our results were compared with those published from various centres.

Setting: Regional hospital, Hong Kong.

Patients: A total of 28 consecutive patients who had undergone bipolar transurethral enucleation and resection of the prostate by a single surgeon between January and June 2014. All patients were evaluated preoperatively by physical examination, digital rectal examination, transrectal ultrasonography, and laboratory studies, including measurement of haemoglobin, sodium, and prostate-specific antigen levels. Patients were assessed perioperatively and at 4 weeks and 3 months postoperatively.

Results: The mean resected specimen weight of prostatic adenoma in 28 patients was 48.2 g with a mean enucleation and resection time of 13.6 and 47.7 minutes, respectively. There was a mean decrease in serum prostate-specific antigen by 85.9% (from 6.4 ng/mL to 0.9 ng/mL) postoperatively. Prostate volume was decreased by 68.2% (from 71.9 cm(3) to 22.9 cm(3)) at 4 weeks postoperatively. The mean postoperative haemoglobin drop was 11.5 g/L. The rate of transient urinary incontinence at 3 months was 3.6%. Patients who underwent bipolar transurethral enucleation and resection of the prostate had a short catheterisation time and hospital stay, which is comparable to conventional transurethral resection of the prostate.

Conclusions: Bipolar transurethral enucleation and resection of the prostate should become the endourological equivalent to open adenomectomy with fewer complications and short convalescence. The technique of bipolar transurethral enucleation and resection of the prostate can be acquired safely with a relatively short learning curve.
