En bloc greenlight laser enucleation of prostate (GreenLEP): about the first hundred cases

A Commentary to this article is available

Abstract

Purpose

To report the functional outcomes, perioperative morbidity and surgical learning curve key points using “en bloc” greenlight enucleation of prostate (EB-GreenLEP) for patients with refractory lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH).

Methods

Between December, 2015 and May, 2018, all consecutive patients with refractory LUTS due to BPH in our institution were included and underwent EB-GreenLEP by a single surgeon. Perioperative data, complications and functional outcomes at 1-, 6- and 12-month follow-ups were collected and retrospectively analyzed.

Results

One hundred patients were included whose median age was 69 years. The median prostate volume (PV) was 84 mL and median enucleated PV was 45.5 mL. Mean irrigation, catheterization and hospitalization times were 1.3, 1.4 and 1.6 days, respectively. Average follow-up was 9.3 months. A single high-grade Clavien-Dindo complication occurred. No urinary retention was reported. Two conversions to conventional resection of the prostate were noted. Three patients had postoperative urinary incontinence at 6 months, only one at 1 year (1%). At 1, 6 and 12 months, there was a significant improvement in IPSS score, QoL and Qmax. Enucleation and energy efficiency ratios were shorter after the 30th procedure. We demonstrated a linear correlation between enucleation time and PV (r = 0.53, p < 0.0001).

Conclusion

Our study shows that the mid-term functional results of EB-GreenLEP are comparable to other laser sources for the endoscopic enucleation of the prostate but with a shorter learning curve. We showed that, with (a) low rates of complications and a short hospital stay, EB-GreenLEP can manage medium-size glands (60–90 mL).
