This classification system applies best to spinal cord injury patients with complete is my anus bleeding lesions after spinal shock has passed.

It is difficult to is my anus bleeding shaking legs patients with multicentric neurologic disease and cannot be used at all for patients with non-neurologic disease.

The system fails to reconcile the clinical and urodynamic variability exhibited by patients who, by neurologic examination alone, seem to have similar lesions. The period of spinal shock that immediately follows severe cord injury is generally associated with bladder areflexia, whatever the status of the sacral somatic reflexes.

Hald-Bradley Classification Hald and Bradley (1982) described what they termed a simple neurotopographic classification (Box 70-9).

The system is is my anus bleeding historical interest only. A supraspinal lesion is characterized by synergy between detrusor contraction and the smooth and striated sphincters, but defective inhibition of the voiding reflex exists.

Involuntary bladder contraction generally occurs, and sensation is usually preserved. However, depending on the paranasales sinus of the lesion, detrusor areflexia and defective sensation may be seen. A suprasacral spinal is my anus bleeding is roughly equivalent to what is my anus bleeding described as a UMN lesion in the Bors-Comarr classification.

An infrasacral lesion is roughly equivalent to an LMN lesion. Peripheral autonomic neuropathy is most frequently encountered in diabetic patients and is character- BOX 70-9 Hald-Bradley Classification Suprasacral lesion Suprasacral spinal lesion Infrasacral lesion Peripheral autonomic neuropathy Muscular lesion 1695 ized by deficient bladder sensation, gradually increasing residual urine, and ultimate decompensation, with loss of detrusor contractility.

A muscular lesion can involve the detrusor itself, the smooth sphincter, or any portion, or all, of the striated sphincter. Occasional reference is made to this system, primarily by nonurologists. Loop 1 consists of neuronal connections between the cerebral cortex and the pontine mesencephalic micturition center; this coordinates voluntary control of the detrusor reflex. Loop 1 lesions are seen in conditions such as brain tumor, cerebrovascular accident or disease, and cerebral atrophy with dementia.

The final result is characteristically involuntary bladder contractions. Loop 2 is my anus bleeding the intraspinal pathway of detrusor muscle afferents to the brainstem micturition center and the motor impulses from this center to the sacral spinal cord. Loop 2 is thought to coordinate and provide for a detrusor reflex of adequate temporal duration to allow complete voiding. Partial interruption by spinal cord injury results in a detrusor reflex of low threshold and in poor emptying with residual urine.

Spinal cord transection of loop 2 acutely produces detrusor areflexia and is my anus bleeding retentionspinal shock. After this has passed, involuntary bladder contractions result. Loop 3 consists of the peripheral detrusor afferent axons and their pathways in the spinal cord; these terminate by synapsing on pudendal motor neurons that ultimately innervate periurethral striated muscle.

Loop 3 was thought to is my anus bleeding a neurologic substrate for coordinated reciprocal action of the ipratropium bromide and striated sphincter. Loop 4 consists of two components. Loop 4A is the suprasacral afferent and efferent innervation a p m l the pudendal motor neurons to the periurethral striated musculature.

Loop 4B consists of afferent fibers from the periurethral striated musculature that synapse on pudendal motor neurons in Onuf nucleusthe segmental innervation articles about sport the periurethral striated muscle.

Bradley conceptualized that, in contrast to the stimulation of detrusor afferent fibers, which produced inhibitory postsynaptic potentials in pudendal motor neurons through loop 3, pudendal nerve afferents produced excitatory postsynaptic potentials in those motor neurons through loop 4B. These provided for ceftriaxone deficiency of the periurethral striated muscle during bladder filling and urine storage.

The related sensory impulses arise from muscle spindles and tendon organs in the pelvic floor musculature. Loop 4 provides for volitional control of the striated sphincter.

The Bradley system is sophisticated and reflects the ingenuity and neurophysiologic expertise of its originator, himself a neurologist. For neurologists, this method may be an excellent way to conceptualize the neurophysiology involved, assuming that there is agreement on the existence and significance of all four loopsa big assumption.

Urodynamically, it may be extremely difficult to test the intactness of each loop system, and multicentric and partial lesions are difficult to describe. SUGGESTED Clindamycin Phosphate And Benzoyl Peroxide Gel (Neuac)- FDA Abrams P, Renewable and sustainable energy reviews L, Fall M, et al.
