[Novel surgical techniques for treatment of benign prostatic hyperplasia].

In recent years new surgical techniques to treat benign prostatic hyperplasia have been introduced into urological practice and evaluated in clinical studies. Complications of standard procedures, e.g. transurethral resection of the prostate (TURP), can be avoided while maintaining equivalent clinical outcomes. The main goal is preservation of erectile and ejaculatory function. Furthermore, outpatient treatment associated with a rapid patient recovery would be desirable. This article presents the course of the interventions, the mechanisms of action and current clinical evidence for novel mechanical approaches of recanalization, water-based ablation as well as prostate artery embolization. Initial study results partially indicate that in the future practically all patients can be offered an individualized surgical technique, which provides optimal symptomatic and functional improvements with a minimized risk of complications.
