Abstract

Objectives

To describe peri‐operative results, functional outcomes and complications of laser photoselective vaporization, using the GreenLight system, of prostate glands ≥200 mL in volume.

Methods

Retrospective analysis of a prospectively maintained multicentre database was performed to select a subgroup of patients with very large prostates (volume ≥200 mL) treated with the GreenLight XPS laser. A subgroup of patients with prostate volumes 100–200 mL was used for comparison. International Prostate Symptom Score, maximum urinary flow rate, postvoid residual urine volume and prostate‐specific antigen levels were measured at 6, 12, 24, 36 and 48 months. Durability was evaluated using benign prostatic hyperplasia re‐treatment rate at 12, 24 and 36 months. Additionally, complications were recorded using Clavien–Dindo classification.

Table 2. Peri-operative results of 88 patients treated with XPS GreenLight stratified according to prostate volume (≥200 mL or 100–199 mL).

Results

A total of 33 patients (38%) had prostates ≥200 mL. Baseline characteristics were similar between patients with prostates ≥200 mL and those with prostates 100–200 mL. Patients with very large prostates (≥200 mL) had longer operating times (129 vs 93 min), less energy delivered, a greater number of fibres used (3 vs 2) and a higher conversion rate to transurethral resection of the prostate (16% vs 4%). In terms of complications and functional outcomes, we did not find any differences between the groups. Retreatment rate was also comparable.

Conclusions

Our results show that PVP GreenLight XPS‐180W is an acceptable technique for very large prostates (≥200 mL); however, operating times, energy delivery, fibres used and conversion to TURP are a concern in this particular subgroup. This should be used for patient counselling and surgery planning.
