Vaginal packing volume impact on dose parameters during radiography and computed tomography based postoperative brachytherapy of cervical carcinoma.

CONCLUSION: If the brachytherapy vaginal packing is of a large volume (more than 25.6 cm3), an asymmetric deformation of the proximal part of the vaginal cavity might appear, leading to inappropriate dose coverage of the CTV part of the vaginal mucosa. Also, making a vaginal packing volume larger than 25.6 cm3 made no further reduction in the bladder dose, but it made a statistically significant further reduction in the rectal doses.
