The current report concerns the unusual symptom of intermittent priapism, or what may be termed 'involuntary penile erection', associated with proven degenerative lumbar spinal stenosis. Seven patients who were treated for intermittent claudication and spontaneous priapism during walking were studied in terms of clinical presentation, imaging findings, and some electrophysiological testing. Varying degrees of walking and standing tolerance with these unusual symptoms appeared to be correlated with cauda equina constriction as was seen by radiological imaging. Although not statistically valid, external urethral sphincter evoked electromyography suggested the possibility of monitoring the unusual symptom during walking. Surgical spinal decompression is recommended to alleviate this symptom and the claudication.
本报告涉及间歇性阴茎异常勃起这一罕见症状，或可称为“非自主性阴茎勃起”，其与经证实的退行性腰椎管狭窄相关。对7例在行走过程中出现间歇性跛行和自发性阴茎异常勃起而接受治疗的患者，从临床表现、影像学检查结果及一些电生理检查方面进行了研究。影像学检查显示，这些异常症状的不同程度的行走和站立耐受似乎与马尾神经受压相关。尽管无统计学意义，但尿道外括约肌诱发肌电图提示了在行走过程中监测这一异常症状的可能性。建议行脊柱减压手术以缓解此症状及跛行。
