国产膀胱容量测定仪在神经源性膀胱间歇导尿患者中的应用研究

摘要

Objective To explore the application of domestic bladder capacity scanner in intermittent catheterization in patients with neurogenic bladder. Methods 40 patients with neurogenic bladder accepted intermittent catheterization. Their bladder volume was tested with domestic and imported bladder capacity scanner (Padscan and Bladderscan) and catheterization respectively. Results The bladder vol-ume was (262.592 ± 6.3012) ml tested by Padscan, and was (262.570 ± 6.3006) ml by Bladderscan (P>0.05). The bladder volume tested by bladder catheterization was (245.549±6.0511) ml, which was significantly lower than the other methods (P<0.001), but the D-value was just 17 ml. Conclusion The accuracy of bladder volume tested by domestic bladder capacity scanner (Padscan) was very similar with the import-ed one (Bladderscan), and the difference between them and the volume tested by bladder catheterization was meaningless in clinical.%目的：探讨国产膀胱容量测定仪在神经源性膀胱患者间歇导尿中的临床应用价值。方法对40例因神经源性膀胱接受间歇导尿的患者分别采用国产(Padscan)、进口(Bladderscan)膀胱容量测定仪及导尿法进行膀胱容量的测定。结果共测量377次。三种方法测得膀胱容量有非常高度显著性差异(F=25.32, P<0.001)。国产膀胱容量测定仪(Padscan)测得膀胱容量为(262.592±6.3012) ml，进口膀胱容量测定仪(Bladderscan)测得膀胱容量(262.570±6.3006) ml，两者相比无显著性差异(P>0.05)；导尿法测得膀胱容量为(245.549±6.0511) ml，显著低于另两种方法测得的膀胱容量(P<0.001)，但平均差值仅为17 ml。结论国产膀胱容量测定仪(Padscan)测量神经源性膀胱患者膀胱容积的准确性与进口仪器非常相近，与导尿法测量值的差异无临床意义。
