Abstract
Transurethral resection of the prostate (TURP) has been the gold standard treatment of obstructive benign prostatic hyperplasia (BPH) for several decades. During the last five years, however, numerous new treatment modalities have been introduced: stents, thermo-therapy, balloon dilatation, resection with laser or high intensity focused ultrasound and pharmacology (α-blockers, 5-alpha-reductase inhibitors). When adding these new modalities to our treatment options it is mandatory to compare them with the traditional treatment. For the comparison it is necessary to know both advantages and disadvantages of the traditional treatment. One of the long term complications to TURP is sexual dysfunction. This phenomenon is not well investigated and therefore incompletely understood.
