Radiotherapie des Prostatakarzinoms: Kontrolle der Blasenfüllung
Radiotherapy of Prostate Cancer: Controll of Bladder Filling
Bei der Radiotherapie von Prostatakarzinomen ist ein konstantes Blasenvolumen notwendig. Die Kontrolle kann mittels Ultraschallgerät erfolgen. Die Vorteile gegenüber einer Cone-Beam-CT liegen in der Zeit- und Dosisersparnis. Ein regelmäßiges Feedback hilft den Patienten, das Blasenvolumen vor der Bestrahlung einzuschätzen. Dieser Artikel erläutert die Rolle der Blase bei Prostatabestrahlungen und wie das Volumen kontrolliert werden kann.
In radiotherapy of prostate cancer a constant daily bladder filling and its verification is essential. To achieve this, an ultrasound measurement can be utilised. In comparison to cone-beam CT, such a measurement is less time consuming and does not apply additional ionizing radiation. Furthermore, it improves the patients’ self-assessment of the bladder volume due to the feedback given. However, due to improved image guidance options, ultrasound will hardly be able to expand its limited role in image-guided radiotherapy beyond current applications.
