Benign hypertrophy of the prostate (BPH) is the most frequent pathology in the urinary tract of middle-aged men. In recent years, to enable BPH treatment with larger volumes and to reduce the risk of hemorrhage known to be associated to the transurethral resection of prostate treatment, transurethral photovaporisation of the prostate (PVP ) with the GreenLight (GL) XPS 180 W was developed. Therefore, the question arises to maximally reduce the length of catheterization to facilitate outpatient surgical management of prostate adenoma.
