Jym, if you are considering LDR brachytherapy your urologist and/or RO should check your AUA Symptom Score
www.prostatechicago.com/forms/aua-symptom-score.pdfIf you have a score much above 15 or if you have significant retention post-voiding, then you may not be a good candidate for LDR brachy. However, I'm not sure about
the constraints for HDR brachy so perhaps one of the HDR guys will chime in as well.
Hope this helps.
Jim
