A retrospective audit on the "Plan of the day" (POD) selection and intra-fractional bladder fillings were carried out on twenty adaptive bladder radiotherapy patients at a single institution. Treatment time, differences in bladder volume and displacement of outer bladder wall expansion over the treatment fraction were analysed. Average treatment time was 8.9 min. The mean percentage difference in bladder volume pre and post treatment was 13.7%, resulting in expansion of the bladder predominately in the superior and anterior directions. This audit confirmed that the institution's POD process sufficed without being significantly affected by the intra-fractional bladder filings.
对一家机构的20名接受适应性膀胱放疗的患者进行了关于“当日计划”（POD）选择和分次内膀胱充盈的回顾性审计。分析了治疗时间、膀胱体积差异以及治疗分次中外膀胱壁扩张的位移。平均治疗时间为8.9分钟。治疗前后膀胱体积的平均百分比差异为13.7%，导致膀胱主要在上方和前方扩张。此次审计证实，该机构的POD流程足够，且未受到分次内膀胱充盈的显著影响。
