Vaginal stenosis and dilator use after pelvic brachytherapy.

INTRODUCTION

To prevent vaginal stenosis, the use of a vaginal dilator is recommended.

OBJECTIVE

To analyze sociodemographic data, gynecological conditions and the use of vaginal dilator after pelvic brachytherapy.

MATERIALS AND

METHODS

Cross-sectional, retrospective study, period 2016-2020, collected between October/2020 and February/2021, from records of women with gynecological cancer treated with brachytherapy at the Centro de Pesquisa Oncológicas (Brazil). The variables included sociodemographic data and gynecological conditions in following the treatment. In the analysis, descriptive statistics, chi-squaretest, Fisher's exact test and Mann-Whitney test were applied.

RESULTS

519 patients records were included in the investigation; the analyzes showed significant associations between the topography and staging (p<0.001), education (p=0.004) and age (p<0.001); the comparison between the distribution of the ionizing radiation dose showed a difference with the continued sexual relationship category (p=0.006); the comparison between the proportions ofcontinued sexual relationship and using a vaginal dilator was significant (p<0.001); 49.10% (131) adhered to the use of vaginal dilator; 24.50% (127) are not sexually active and do not adhere to the use ofthe dilator.

DISCUSSION: It is evident that social and gynecological conditions interfere with the presence of vaginal stenosis and the use of a vaginal dilator after pelvic brachytherapy.

CONCLUSIONS

The adherence found in the use of dilator affirms the contributions and the need for health education by nurses and physicaltherapists during and following the treatment.
