Post\u2010implant dosimetry was similar for the prostate gland target volumes and significantly reduced for the urethra and bowel in HG patients relative to WG controls, but this did not translate into a difference in post\u2010implant mean symptom scores between the two groups. Nevertheless, the change in score from baseline indicated that the impact on pre\u2010treatment symptom status was less after HG implants. Only HG patients showed a return to baseline urinary scores as early as 12\u00a0months. Sexual potency was conserved in 73% and 67% of HG and WG patients, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a00.84).
