Transurethral enucleation and resection of prostate in patients with benign prostatic hyperplasia by plasma kinetics.

PURPOSE

We evaluated transurethral enucleation and resection of the prostate in patients with urinary symptoms due to benign prostatic hyperplasia using the Plasmakinetic™ system.

MATERIALS AND METHODS

We retrospectively analyzed the records of 1,100 patients who underwent transurethral enucleation and resection of the prostate between January 2003 and February 2009 at our institution. We assessed the International Prostate Symptom Score, quality of life score, peak flow rate and post-void residual urine volume preoperatively, 1, 3, 6 and 12 months postoperatively, and yearly thereafter. Enucleation and resection time, enucleated tissue weight, catheterization time, hospital stay and long-term complications were recorded.

RESULTS

No patient had significant blood loss or signs of the transurethral resection syndrome. Mean±SD patient age was 66.7±7.3 years and mean followup was 4.3 years. Mean preoperative prostate weight was 67.7±12 gm (range 35 to 256), mean enucleation time was 15.5 minutes (range 10 to 38), mean resection time was 46 minutes (range 20 to 65) and mean resected tissue weight was 42.8±7.7 gm (range 23 to 219). Mean catheter time was 1.8±0.4 days and mean hospital stay was 5.3±2.3 days. Transurethral enucleation and resection of the prostate induced significant, pronounced, immediate and lasting improvement in the International Prostate Symptom Score, quality of life, maximum urinary flow and post-void residual urine volume. Postoperative complications included meatal stenosis in 9 cases, incontinence in 56, urethral stricture in 12 and bladder neck contracture in 10.

CONCLUSIONS

Transurethral enucleation and resection of the prostate appears to be the modern alternative to transurethral resection of the prostate and open prostatectomy for bladder outlet obstruction due to benign prostatic hyperplasia. It may be done in glands up to 250 gm.
