Intermittent priapism in spinal canal stenosis

Area of Science:

• Neurology
• Urology
• Spinal Surgery

Background:

• Spinal canal stenosis is a condition characterized by narrowing of the spinal canal, potentially compressing neural elements.
• Priapism, a persistent erection unrelated to sexual stimulation, can have various underlying causes, including neurological factors.
• Intermittent neurogenic claudication and urinary incontinence are recognized symptoms associated with lumbar spinal stenosis.

Observation:

• A patient presented with spontaneous intermittent priapism.
• The priapism episodes, along with neurogenic claudication and urinary incontinence, were consistently provoked by physical exertion, particularly walking.
• These symptoms were linked to the presence of spinal canal stenosis.

Findings:

• The patient's symptoms of priapism, neurogenic claudication, and urinary incontinence were directly correlated with physical exertion.
• Decompressive lumbar laminectomy was performed to alleviate the spinal canal stenosis.
• Following the surgical intervention, all symptoms, including priapism, completely resolved.

Implications:

• This case highlights a potential, previously under-recognized, neurological cause of spontaneous intermittent priapism.
• It suggests that spinal canal stenosis can manifest with a constellation of symptoms including priapism, claudication, and incontinence.
• Surgical decompression of lumbar spinal stenosis may offer a curative treatment for associated priapism, improving patient quality of life.
