To validate the results of the home penile tumescence monitor versus the sleep laboratory studies of erectile function.
We used both methods to study 18 episodes of rigidity and 19 episodes of tumescence in 10 subjects with erectile dysfunction before and after the use of an experimental vasodilating medication.
The tumescence measurement in the sleep laboratory compared favorably with the changes in tumescence with the RigiScan portable home monitor: at the base (r = 0.70; P < 0.001), and at the tip (r = 0.84; P < 0.001). In measuring rigidity, the buckling pressure in the sleep laboratory compared favorably with the RigiScan measurements of percent average rigidity at the base (r = 0.56; P = 0.017), at the tip (r = 0.62; P = 0.006), and mean rigidity of the base and tip (r = 0.64; P = 0.004). In a comparison of the buckling pressure with the new RigiScan Plus quantitative program, there was good correlation with the rigidity activity units at the base (r = 0.70; P = 0.001) and at the tip (r = 0.72; P < 0.001). A clinical estimate of penetrable rigidity correlates with the RigiScan base rigidity of 55% to 60% and tip rigidity of about 50%.
The portable home monitor is a viable and cost-effective clinical tool to measure nocturnal penile activity.
验证家用阴茎勃起监测仪与睡眠实验室勃起功能研究结果的一致性。
我们使用这两种方法对10名勃起功能障碍患者在使用一种实验性血管扩张药物前后的18次阴茎硬度发作和19次勃起发作进行了研究。
睡眠实验室中的勃起测量结果与RigiScan便携式家用监测仪的勃起变化情况相比表现良好：在阴茎根部（r = 0.70；P < 0.001），以及阴茎头部（r = 0.84；P < 0.001）。在测量阴茎硬度方面，睡眠实验室中的屈曲压力与RigiScan测量的阴茎根部平均硬度百分比（r = 0.56；P = 0.017）、阴茎头部（r = 0.62；P = 0.006）以及阴茎根部和头部的平均硬度（r = 0.64；P = 0.004）相比表现良好。在将屈曲压力与新的RigiScan Plus定量程序进行比较时，与阴茎根部（r = 0.70；P = 0.001）和阴茎头部（r = 0.72；P < 0.001）的硬度活动单位有良好的相关性。可穿透硬度的临床估计与RigiScan测量的阴茎根部硬度55%至60%以及阴茎头部硬度约50%相关。
便携式家用监测仪是一种可行且经济高效的测量夜间阴茎活动的临床工具。
