Anesthesia choice for prostate brachytherapy does not impact gland swelling, toxicity, or implant quality. This study found no significant differences in outcomes between general and spinal anesthesia for prostate implants.

Area of Science:

  • Urology
  • Radiation Oncology
  • Anesthesiology

Background:

  • Prostate brachytherapy outcomes depend on radiation dose and distribution.
  • Postoperative swelling can alter seed spacing, affecting intended radiation delivery.
  • General anesthesia has been linked to increased bleeding in prostate surgery.

Purpose of the Study:

  • To evaluate the effect of anesthesia type (general vs. spinal) on prostate gland swelling.
  • To assess the impact of anesthesia on implant dosimetric quality (D90, V100).
  • To determine if anesthesia choice influences acute toxicity following prostate brachytherapy.

Main Methods:

  • Retrospective review of 83 iodine prostate implants performed by a single radiation oncologist.
  • Analysis of gland volume changes from pre- to post-procedure imaging.

  • Comparison of dosimetric parameters (D90, V100) and acute toxicity (urinary retention, bruising) between anesthesia groups.

    • Main Results:

    • No significant difference in median prostate volume increase between general and spinal anesthesia groups (23% vs. 23.5%).
    • Similar D90 (115% vs. 113%) and V100 (97% vs. 96.5%) values were observed.
    • Acute toxicity rates, including urinary retention and bruising, were comparable across anesthesia types.

    Conclusions:

    • Anesthesia selection for prostate brachytherapy does not appear to influence prostate swelling.
    • The choice of general or spinal anesthesia did not affect implant dosimetric quality.
    • Results suggest anesthesia type does not impact acute toxicity in prostate brachytherapy patients.
