Prostate Volume Changes Following Prostate Brachytherapy With Iodine-125 Seeds

An Observational Study to Evaluate the Changes in Prostate Volume Over Time With The Use of Transrectal Ultrasound and Computed Tomography Following Permanent Prostate Brachytherapy With Iodine-125 Seeds.

The size of the prostate changes due to insertion of the radioactive seeds. We will measure the prostate size, before and after the procedure.

The prostate size will be measured using the TRUS and CT scan on days -1, 0, 1, 9, 30, and 60 days after the brachytherapy procedure.

Inclusion Criteria:

• Pathologically confirmed diagnosis of prostate cancer
• T1-3 disease
• PSA <20 ng/ml
• Patient must sign a study-specific informed consent prior to enrollment.

Exclusion Criteria:

• Patients ineligible to brachytherapy
