Background:
The continuous wave 2-μm Thulium Laser has been introduced as potential technology with both high efficiency and safe practice; although little data have been shown regarding the long-term outcomes.
Objective:
To analyze the long-term outcomes after thulium vaporesection of the prostate (ThuVaRP).
Methods:
ThuVaRP was performed using the continuous wave, 2-μm Thulium: YAG laser at 70 W. The perioperative and post-operative follow-up data were analyzed.
Results:
The average age at surgery was 71.5 (range 55-94 years). The median prostate size was 60.1 g (range 36.3-109.8 g). A median operation time was noted at 44.8 ± 6.5 minutes, while the median catheterization time was 3.5 ± 0.5 days. In regards to hospital stay, most patients had an average duration of 5.5 ± 1.5 days. Minor complications requiring non-interventional treatment happened in 237 (36.24%) of 654 patients, while major complications requiring re-interventions occurred in one patient (0.15%). During a 60-month follow-up, bladder neck fibrosis occurred in 1.22% of the patients. A BPH recurrence happened in 17 (2.60%) patients, of which 14 patients (2.14%) received a second surgery. In comparison to the pre-operative baseline, the patients Qmax, PVR volume, IPSS, and Qol scores all improved significantly (P < 0.01) at time of discharge. This continued into the post-operative follow-up visits (3-6-12-18-14-26-48-60 months).
Conclusions:
ThuVaRP is both an effective and safe treatment procedure for symptomatic BPO (with a low occurrence of complications). Lasers Surg. Med. 48:505-510, 2016. © 2016 Wiley Periodicals, Inc.
