Use of Botox to Treat Scrotal Pain

Use of Botox to Treat Scrotal Pain

There are no previous reports on the use of Onabotulinum Toxin A to treat men with scrotal pain that we found published. We propose a pilot study to use Botox to block the testicular nerves on a group of 15 men with chronic scrotal pain who have failed the standard medical therapy. The men must have had temporary relief from a testicular cord block using marcaine. Before and 1 month, 3 months and 6 months after the Onabotulinum Toxin A injection, the men would be asked to fill in visual analog scales for pain, a quality of life assessment, a depression index (MDI) and Chronic Epididymitis Symptom Index (CESI). They will also be subject to sensory testing of the scrotum before, after 1 month, 3 moths and 6 months.

Inclusion Criteria:

• Age 18-65
• Have nociceptive scrotal pain,
• Have no identifiable, reversible causes for the scrotal pain
• Have failed standard medical therapy
• Have responded temporarily to cord blocks

Exclusion Criteria:

• Are interested in trying to conceive with their partners in the next 6 months,
• Have any local infection near the site of the injections,
• Have had an allergic reaction to Botox in the past,
• Are unable to provide informed consent
• Have a history of motor neuron disease or neurogenic bladder
• Who have hemostatic disorder or who are taking aspirin, Coumadin (warfarin), Xarelto (rivaroxaban) or other blood thinners
