[Case-based presentation of the S2e guideline on the diagnosis and treatment of benign prostatic hyperplasia]

Benign prostatic hyperplasia (BPH) is the most common disease of the lower urinary tract in men. The prevalence increases continuously with increasing age and a chronic progressive course is to be expected. In order to reduce the morbidity of affected patients and to improve their quality of life, the expert panel Benign Prostatic Hyperplasia (BPH) of the German Society of Urology (DGU) has written a new version of the evidence-based "S2e guideline on the diagnosis and treatment of BPH". Using a current patient case, the contents of the new S2e guideline are illustrated, from diagnosis to the decision-making process for a suitable treatment choice. The case presented here shows the possible complexity and difficulty that can arise in the diagnosis of BPH, the need for further diagnostic steps and the finding of a suitable therapy in order to fulfill the patient's wishes, if possible.
