OBJECTIVE
To determine the ability of sphincter electromyography (EMG) and post-void residual urine volume (PVR) during a free-flow study and a pressure-flow study (PFS) for distinguishing multiple system atrophy (MSA) from Parkinson's disease (PD).
METHODS
We retrospectively reviewed 241 case records; both urodynamic study and sphincter EMG were performed in patients with MSA (n = 147) and PD (n = 94).
RESULTS
There was a statistically significant difference (p < 0.01) in the mean PVR during the free-flow study (113.1 ± 7.5 mL in MSA and 40.4 ± 3.8 mL in PD), mean PVR during PFS (230.1 ± 12.6 mL in MSA and 71.7 ± 6.6 mL in PD), and mean duration of MUP for sphincter EMG (9.3 ± 0.1 ms in MSA and 7.7 ± 0.1 ms in PD). The area under the curve used for differentiating MSA from PD was 0.79 and 0.73 for PVR during PFS and the free-flow study, respectively. There was a mean duration of 0.69 ms for the sphincter EMG.
CONCLUSIONS
The present results suggested that PVR was more appropriate than sphincter EMG for differentiating MSA from PD.
目的
确定在自由尿流试验和压力-流率试验（PFS）期间，括约肌肌电图（EMG）和排尿后残余尿量（PVR）区分多系统萎缩（MSA）与帕金森病（PD）的能力。
方法
我们回顾性分析了241例病例记录；对MSA患者（n = 147）和PD患者（n = 94）均进行了尿动力学检查和括约肌EMG检查。
结果
自由尿流试验期间的平均PVR（MSA组为113.1±7.5 mL，PD组为40.4±3.8 mL）、PFS期间的平均PVR（MSA组为230.1±12.6 mL，PD组为71.7±6.6 mL）以及括约肌EMG的运动单位电位平均时限（MSA组为9.3±0.1 ms，PD组为7.7±0.1 ms），差异均具有统计学意义（p < 0.01）。PFS期间和自由尿流试验期间用于区分MSA与PD的曲线下面积分别为0.79和0.73。括约肌EMG的平均时限为0.69 ms。
结论
目前的结果表明，在区分MSA与PD方面，PVR比括约肌EMG更合适。
