摘　　要：目的探讨性别、年龄、体质量指数(BMI)和病种对膀胱容量测定仪准确性的影响。方法招募121例盆腔肿瘤放疗患者,在CT模拟定位前0.5 h让患者饮水500 mL,CT定位扫描完成后使用膀胱容量测定仪进行膀胱容量测量,比较测定仪结果与CT定位时的膀胱容量的差异,分析可能影响患者膀胱容量准确性的因素。结果膀胱测定仪测量结果与CT测量结果的差别无统计学意义(P>0.05);性别对CT-膀胱测定仪差值的影响显著(P<0.05),女性患者膀胱容量离散程度更大;BMI、年龄和病种对CT\|膀胱测定仪差值的影响无统计学意义(P>0.05)。结论在盆腔肿瘤分次放疗前使用膀胱容量测定仪作为辅助设备评估膀胱容量,其结果与定位CT膀胱容量测量结果的差别无统计学意义,但性别对膀胱容量测定仪的准确性有一定影响。Objective To explore the effects of gender,age,body mass index(BMI)and disease type on the accuracy of bladder volume scanner.Methods 121 pelvic tumor radiotherapy patients were recruited.Patients were instructed to drink 500 mL of water 0.5 h before CT simulation positioning.After CT simulation positioning scanning was completed,bladder volume was performed using a bladder volume scanner.The difference between the results of the bladder volume scanner and the bladder volume during CT simulation positioning was compared,and factors that may affect the accuracy of the patient s bladder volume were analyzed.Results There was no statistically significant difference(P>0.05)between the results of the bladder volume scanner and CT.The gender factor had a statistically significant impact on the difference in CT and bladder volume scanner(P<0.05),and female patients had a greater degree of bladder volume dispersion.BMI,age and disease type had no statistically significant effect on the difference between CT and bladder volume scanner(P>0.05).Conclusion The use of a bladder volume sccanner as an auxiliary device to evaluate bladder volume before fractionated radiotherapy for pelvic tumors showed no statistically significant difference compared to the results of CT bladder volume measurement.However,gender has a certain impact on the accuracy of the bladder volume scanner.
