Detrusor hyperreflexia in neurogenic bladder disorders caused by localized partial lesions of the spinal cord and cauda equina.

In 70 patients studied by cystometry, detrusor hyperreflexia seen with localized partial lesions of the spinal cord and cauda equina could be differentiated into two types. In one type, in which the hyperreflexia was of a reflex nature and bladder compliance was unchanged, the detrusor contractility was described as compliant hyperreflexic. In the other type, in which the contractions were of a rhythmic nature and accompanied by reduced compliance, the contractility of the detrusor was described as noncompliant hyperreflexic. The compliant hyperreflexic contractions correlated well with signs of upper motor neuron disturbance, the noncompliant hyperreflexic contractions with lower motor neuron disturbance.

Nomenclature of neurogenic bladder.

Vesicourethral physiology is reviewed briefly in the light of recent developments. The effect on bladder function of central nervous system disorders is considered and attention is drawn to the desirability of diverting interest from the bladder to the urethra in neuropathic cases. It is concluded that there are only two basic types of neuropathic bladder function--in lesions of and above the sacral reflex pathways, respectively. Neurologically these are classified according to the condition of the anal and bulbocavernosus reflexes and the ice water test.

Dual pressure transducer catheter for evaluating vesicourethral function: experiences in patients with neurogenic bladder.

Preliminary experiences with a dual pressure transducer catheter (7 F) for the functional vesicourethral evaluation are described. Synchronous cystosphincterometric recording, urethral pressure profile with simultaneous intravesical pressure, and pressure gradient across urethral sphincter were obtained. Comparison of the studies with those conducted with catheter infusion technique revealed that minimal artefacts were encountered with the former although the pressure events displayed by the two methods were grossly similar.

Early detection of neurogenic bladder dysfunction caused by protruded lumbar disk.

A case of cauda equina compression was suspected from urinary symptoms. The diagnosis was based on the presence of type A contraction on rapid cystometry and prolonged latency of the sacral evoked response. Such findings pointed to the need for myelography. Lumbar laminectomy, with removal of a ruptured intervertebral disk and cauda equina decompression, resulted in return of normal urination and normal cystometry and electromyogram of the perineal muscles.

Results of clean intermittent catheterization for children with neurogenic bladders.

Forty-nine patients were placed on a regimen of clean intermittent catheterization one to four years prior to this review. The children were intermittently catheterized, and a silver nitrate solution 1:1000 was instilled after each catheterization. Nurse practitioners, and community and school personnel contributed to the management. Twenty-one patients were continent with anticholinergics, and 18 also required alpha-adrenergic agents. Eighty-eight per cent were essentially bacteriuria-free, 65 per cent were essentially infection-free, and forty-nine per cent were totally continent. The remaining 25 had mild incontinence. Eleven had clearances below 85 mm/min with 8 reverting to normal on therapy. Nine had reflux prior to the study and one improved. In 8 patients reflux developed during therapy; 4 had severe reflux which required ureteral reimplantation. The results demonstrated that a clean intermittent catheterization program is feasible in a rural setting and that a genitourinary irrigant does decrease bacteriuria.
