| Research Abstract |
It is important for predicting the late morbidity of urethra to evaluate the urethral dose correctly at prostate seed implantation. The difference was seen by the method of the dose calculation in the dose volume histogram. Especially, the difference of 5% on the average was seen in the low to moderate dose area as for the urethra dose. It was thought that the grasp of an accurate urethra dose to evaluate the validity of the measurement became possible.
