Background:
The objective of this study was to describe, in a cohort of patients followed for bladder, bowel or sexual dysfunctions, the occurrence of radicular pain during micturition, defecation and/or orgasm.
Methods:
The study included all patients referred in our neuro-urology department and who suffered from radicular pain before, during or after micturition, defecation and/or orgasm. Data included demographic and medical variables, urodynamic and perineal electromyographic diagnosis.
Results:
A total of 30 patients (men: 70%, mean age 45.4 ± 11.8,) complained of radicular pain before, during or after orgasm (51.4%), micturition (34.3%), or defecation (14.3%). In 30% of cases, radiculopathy was found and was predicted by micturition pain. Other pathologies were as follows: vertebral (16.5%), pelvis and sacral (16.5%), inflammatory central nervous system (10%) lesions and peripheral neuropathies (6.7%). Neurological level of injury was between the lumbar and the sacral level. All spinal cord lesions were lesions of the conus medullaris. Patients also complained of lower urinary tract symptoms (70%), sexual (63.3%) and bowel (60%) disorders. In most cases, the urodynamic diagnosis was neurogenic bladder with peripheral abnormalities and the electromyographic diagnosis was distal neuropathy.
Conclusion:
Radicular pain occurring during micturition, defecation or orgasm is a rare condition. The most common underlying lesion seems to be radiculopathy, from lumbar to sacral spine. The presence of these symptoms, in the absence of any known neurological condition, should suggest the practitioner a radiculopathy in most of the cases. In consequence, appropriate additional tests should be offered to these patients.
Significance:
Few data are available on sciatica during micturition, defecation or orgasm. This study underlines the need for appropriate tests if a patient complaint from this type of symptom. Indeed, the most common underlying lesion is a radiculopathy but can also be a lesion of conus medullaris.

01:26The Micturition Reflex
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Sleep is a fundamental physiological drive that fosters a state of restfulness crucial for several bodily functions. It facilitates body restoration, the process by which the body repairs, rejuvenates, and maintains itself during sleep, including memory...
