This study investigates the use of corpus cavernosum electromyography (CC-EMG) recording as a diagnostic tool for identifying the presence of pelvic autonomic dysfunction (PAD) in patients with LUTS and concurrent ED. Fifty patients were included in the study, and the electromyographic and urodynamic findings were compared. The 50% relaxation degree was accepted as a threshold value for PAD. According to relaxation degree in CC-EMG recordings, patients were grouped as; Group 1 (with PAD) = 23 patients with a relaxation degree of less than 50%. Group 2 (without PAD) = 27 patients with a relaxation degree greater than 50%. The mean age of the patients was 58 ± 3.2 (50–71) years. The comparison of the urodynamic parameters and transrectal ultrasound revealed that the postvoiding residual urine volume (PVR) (p = 0.0007), P det Q_max (p = 0.0005), and P det compliance (0.003) values were statistically significantly lower in Group 2. The mean IIEF-5 and IIEF-15 scores of the patients in Group 1 were 2.5 ± 0.7 and 8.1 ± 1.1 respectively. In Group 2, mean IIEF-5 and IIEF-15 scores were 7.2 ± 2.9, and 17.2 ± 3.5 (p: 0.00023 and p: 0.0009). The mean I-PSS score was 22.8 ± 3 in Group 1 and 16 ± 2.3 in Group 2 (p = 0.001). The mean relaxation degree (RD) in Group I was 30.73 ± 6.8%, and in Group 2 was 66.3 ± 5.1%. The mean amplitude values of the patients in Group I were 261.41 ± 112.97 before papaverine injection, and in Group 2 were 246 ± 101.28 respectively. The inter-group difference was statistically significant (p < 0.05). The mean amplitude value of the patients in Group I after papaverine injection was 182.73 ± 60.71, and in Group 2, that value was 83.2 ± 29.19. The inter-group difference was also significant (p < 0.05). Increased electrical bursts and decreased relaxation responses on CC-EMG indirectly indicated an increase in the contractility of the bladder sphincter. Therefore, we concluded that CC-EMG could be a diagnostic tool for PAD and cavernous autonomic dysfunction.

阴茎海绵体肌电图评估下尿路症状患者的新诊断定义：“盆腔自主神经功能障碍”

本研究调查了使用海绵体肌电图 (CC-EMG) 记录作为诊断工具来识别 LUTS 和并发 ED 患者是否存在盆腔自主神经功能障碍 (PAD)。该研究包括 50 名患者，并比较了肌电图和尿动力学检查结果。50% 的松弛度被接受为 PAD 的阈值。根据 CC-EMG 记录的放松程度，患者分为：第 1 组（使用 PAD）= 23 名放松程度小于 50% 的患者。第 2 组（无 PAD）= 27 名放松程度大于 50% 的患者。患者的平均年龄为 58 ± 3.2 (50–71) 岁。尿动力学参数和经直肠超声的比较显示排尿后残余尿量 (PVR) ( p = 0.0007)、P det Q _max ( p  = 0.0005) 和 P det 依从性 (0.003) 值在第 2 组中显着降低。第 1 组患者的平均 IIEF-5 和 IIEF-15 评分为 2.5 ± 0.7和 8.1 ± 1.1 分别。在第 2 组中，IIEF-5 和 IIEF-15 的平均得分分别为 7.2 ± 2.9 和 17.2 ± 3.5（p：0.00023 和p：0.0009）。第 1 组的平均 I-PSS 得分为 22.8 ± 3，第 2 组为 16 ± 2.3（p = 0.001）。第一组的平均松弛度 (RD) 为 30.73 ± 6.8%，第二组为 66.3 ± 5.1%。第一组患者在罂粟碱注射前的平均振幅值为 261.41 ± 112.97，第二组患者分别为 246 ± 101.28。组间差异具有统计学意义 ( p  < 0.05)。I 组患者注射罂粟碱后的平均振幅值为 182.73 ± 60.71，而第 2 组患者的振幅平均值为 83.2 ± 29.19。组间差异也很显着 ( p  < 0.05)。CC-EMG 的电爆发增加和松弛反应减少间接表明膀胱括约肌收缩力增加。因此，我们得出结论，CC-EMG 可以作为 PAD 和海绵状血管自主神经功能障碍的诊断工具。
