Nocturia has a wide range of causes beyond the urological field. The main causes are polyuria, nocturnal polyuria and disorders of the collection or evacuation function of the bladder.
The individual causes must be carefully distinguished from each other with the predominance of non-invasive diagnosis, as the treatment of individual causes of nocturia is diametrically different. If it is not possible to determine exactly the cause of nocturia on the basis of these methods or nocturia does not respond to the specified treatment, it is necessary to proceed to an invasive examination.
The treatment of nocturia is based on the diagnosed cause and differs diametrically for individual causes of nocturia, although individual treatment modalities can also be combined.
