This can reduce the exposure to those organs and reduce the possibility of side effects.

What type of radiation is used to treat bladder cancer?
The type of radiation most often used to treat bladder cancer is called external beam radiation therapy. It focuses radiation from a source outside of the body on the cancer. Before your treatments start, your radiation team will take careful measurements to find the exact angles for aiming the radiation beams and the proper dose of radiation.
What is the treatment for bladder cancer?
As part of treatment for advanced bladder cancer (cancer that has spread beyond the bladder) Radiation therapy is often given along with chemotherapy to help the radiation work better. This is called chemoradiation.

What is the tube that carries urine from the bladder to the outside of the body?
The urethra is the tube that carries urine from the bladder to the outside of the body. The side effects you get depend on the type of radiotherapy you have and whether you had any urinary problems before your treatment. If you have problems with your bladder before starting radiotherapy this can make them worse.
Why is it so hard to pass urine?

Abstract
To evaluate inter-fractional variations in bladder and rectum during prostate stereotactic body radiation therapy (SBRT) and determine dosimetric and clinical consequences.
Background
Stereotactic body radiation therapy (SBRT) is gaining momentum for its clinical application of the treatment of localized prostate cancer.
Methods
Following Institutional Review Board approval, data were obtained from medical records of 85 consecutive patients treated with 5-fraction SBRT to the prostate from September 2014 to August 2015 at our institution.
Results
Of the 85 total patients, 61 received prescription doses of 40 Gy in 5 fractions, 10 received prescription doses of 37.5 Gy in 5 fractions, and 14 received combination therapy of low dose rate brachytherapy in addition to 5-fraction SBRT to prescription doses of 25 Gy.
Discussion
Optimal bladder and rectal filling for external beam radiation therapy for prostate cancer is a key topic of interest [ 15, 16, 17 ]. Full bladder protocols have the potential to reduce OAR dose exposure via displacement of the small bowel and bladder away from the target volume, with the caveat of increased volume variability [ 18, 19, 20 ].
Conclusions
Despite strict bladder filling instructions and a considerably truncated number of treatment days, a highly variable and decreasing trend in interfractional bladder and rectal volumes were observed in this SBRT cohort during the course of therapy.
