The Injury Prevention Committee of the Japan Medical Society of Paraplegia (JMSoP) conducted a nationwide epidemiological survey on spinal cord injury (SCI) using postal questionnaires for 3 years periods from 1990 to 1992, and the annual incidence of the spinal cord injury was estimated as 40.2 per million. From this registry, we investigated SCI related(More)
Over-distension therapy was performed in 60 patients during the period of spinal shock after complete spinal cord injury. Forty-five developed upper motor neurone (UMN) hypo-active decompensated bladder function and 39 achieved satisfactory social activity without urinary incontinence using self-catheterisation. Self catheterisation appeared a safer and(More)
Ninety patients with spinal cord injury were managed by aseptic intermittent catheterization program I (preventing the over-distension of the bladder) and program II (allowing overdistension) in which recovery of bladder function and the clinical effects were comparatively investigated. Using program I, cases with positive BCR restored the automaticity of(More)
During the last 10 years, 90 penile prostheses were implanted in 82 patients with spinal cord injury. Surgery was done 1 month to 25 years (average 4.8 years) after the injury. The follow up period ranged from 1 to 10 years (average 4 years). A prosthesis was implanted for urinary management in 51 patients (62%), for sexual dysfunction in 10 patients (12%)(More)
During the last 5 years non-inflatable penile prostheses were implanted in 37 patients with spinal cord injury. Operation was done to provide adequate stability of the penis in order to hold an external urinary device, to help erectile impotence and to make self-catheterisation easier. A pair of Shirai-type silicone penile implants were inserted into the(More)
The most frequent medical complication in patients with neurogenic bladder dysfunction is urinary tract infection (UTI). In the acute phase of neurogenic bladder, aseptic intermittent catheterization should be applied. After this phase, patients are subject to UTIs leading to febrile diseases. In the chronic phase of neurogenic bladders, febrile infections(More)
For several weeks before each eruption of Mount St. Helens in 1981 and 1982, viscous magma rising in the feeder conduit inflated the lava dome and shoved the crater floor laterally against the immobile crater walls, producing ground cracks and thrust faults. The rates of deformation accelerated before eruptions, and thus it was possible to predict eruptions(More)
Chronic or recurrent non-obstructive urinary tract infection was investigated in 158 adult patients, 39 of whom had vesicoureteral reflux. Conservative, long-term chemotherapy did not eradicate the reflux in these patients. The characteristics of reflux in adults were studied with cystograms, excretory urograms, cystoscopic findings of the ureteral orifices(More)
To eliminate severe leg spasms of 15 quadriplegics, 0.3 ml 10% phenol-glycerin was injected into the subarachnoid space at the T12/L1 interspace. The effectiveness for leg spasm was evaluated by the Penn spasticity and Ashworth rigidity scales. Three patients remained completely flaccid; however three had slight, six had moderate and three had complete(More)

OBJECTIVES To discuss challenges in the management of spinal bifida patients, who have marked kyphoscoliosis and no vascular access. SETTING Regional Spinal Injuries Centre, Southport, UK.
