Urogenital diaphragm disorders are common causes of anatomical and functional abnormalities which attack women with a greater frequency. Its pathogenesis is still not clear. These alterations are associated, in different degrees, with histological findings, clinical and eletrophysiological chronic partial denervation in the musculature of the pelvic floor.
One of the main eletrophysiological methods described in literature for investigation of the neuronal integrity of the pelvic floor structures are the sacral reflexes. They represent involuntary contractions of a sphincter or pelvic muscle in response to the penian gland stimulation or clitoris, urethra, bladder neck or perineal region. Of these, the most researched are the pudendal-anal reflex, vesico-anal, urethro-anal and anal.
Classically, the sacral reflexes are used for the elucidation of uroneurological alterations, where a suprasacral or sacral defect is suspected; investigation of rectal Incontinence and neurological causes of erectile dysfunctions.
Some centers have used in the investigation of some genitourinary pathologies, possibly related with the pudendal innervation and pelvic autonomous. Genital prolapses, Urinary Incontinence, sensorial disturbances and secondary abnormalities due to deliveries and vaginal surgeries are some alterations where a neuropathic component is associated.
Observe the variations of latency of these reflexes in normal women, in spite of literature descriptions showing well documented similar stories, constitutes a fundamental training for the learning of this methodology.
