Abstract

The objective was to assess and publish our first experiences with the GreenLight XPS™ 180-watt laser in men suffering from bladder outlet obstruction.From January 2013 to February 2014, the results of 142 patients were analyzed prospectively at a single center. Indications for disobstruction were in line with current EAU guidelines, but independent of the underlying causes of obstruction. Assessments were made of the prostate size, International Prostate Symptom Score (IPSS), postvoid residual (PVR) and maximum urinary flow (Qmax). Intraoperative data such as lasing time, surgery time, applied energy and blood transfusions were recorded. Reinterventions and complications were evaluated.The average prostate volume was 29.6 ml (2-82). The average surgery time was 50 min (13-157). Qmax increased by an average of 20.2 ml/s (p < 0.05). On average, PVR was reduced by 162 ml (p < 0.05).The GreenLight XPS™ 180-watt laser is an effective treatment option for bladder outlet obstruction with a low perioperative complications rate, and it shows results comparable with transurethral resection of the prostate. Even multimorbid patients and patients with long-term catheter requirements may be treated due to its high safety profile and reliable results.
