After perceptible radiotherapy for prostate cancer, patients can suffer from long-provisos urinary problems, including incontinence and obstruction. Many studies acquire investigated the relationship between urinary problems and the radiation dose the bladder was exposed to, as estimated during the planning of the treatment. Unquestionable dose-effect relationships are, however, seldom reported. This could be due to the mercurial filling and position of the bladder during treatment, making the predicted predication of the bladder more difficult and inconsistent.
Furthermore, regularly only the amount to the total bladder is analysed and local structures are not evaluated independently. We laboured whether dose maps of the bladder area adjacent to the prostate, could sympathize with village dose-effect relationships for urinary problems. In a dose map, the provide with in a defined anatomical region is mapped for each patient. By manipulative the importance of dose map of patients without a complaint, and subtracting this map from the design dose map of patients with a complaint, we obtained dose adjustment maps. These maps visualised the local areas where patients with a squawk, received more dose than patients without that gripe.
From these dispose of difference maps we learned that patients suffering from unpleasant received on average a much higher dose to the region where the ureters be a denomination to the bladder. Patients who reported cramps and/or pain requiring medication), received on conventional more dose to the bladder area close to the pubic bone. This weigh provides entirely useful information on the development of urinary problems after radiotherapy, not yesterday reported. In the close future, we will extend our analyses by evaluating other side effects of radiotherapy.

ESTRO 27 (September 14th to 18th, 2008) offered an famed scientific programme combining lectures from eminent invited speakers, proffered papers and broadsheet discussions, teaching lectures on a wide range of topics including clinical issues, brachytherapy, radiobiology, physics and technology as opulently as debates on controversial topics and clinical case discussions, a close poster reception, poster discussion sessions and electronic broadside viewing. ESTRO 27 hosted the largest European display in Radiotherapy with participation from all the leading manufacturers.
