Brief Summary

Benign prostatic hyperplasia (BPH) is a prevalent entity, affecting over 50% of men older than 60 years.In cases with moderate to severe lower urinary tract symptoms (LUTS) monopolar transurethral resection of the prostate (TUR-P) is the standard treatment. Especially in frail patients, conventional TUR-P is associated with relevant and potentially deleterious complications, e.g. TUR syndrome. Using isotonic saline, like in bipolar TUR-P and transurethral laser vaporization (TUV-P), TUR syndrome can be prevented. The short-term complication rate with the Thulium laser is similar to the rate described after vaporisation with other laser systems18-23 and less than that with TUR-P. Despite recent publications on the safety and complications with Thulium vaporisation of the prostate, to the investigators knowledge, until now, no prospective trial has directly assessed, whether absorption of irrigation fluid occurs and to what extent in Thulium Laser vaporisation of the prostate. The investigators therefore aim to investigate if absorption of irrigation fluid occurs during Thulium Laser vaporisation of the prostate by expired breath ethanol test.
