Men are more likely to suffer, with a male-to-female ratio of 4:1, but there is high variability in causes and profiles of those injured around the world. New figures suggest an overall incidence between 12 and 65 cases per million individuals per year and that the USA has the highest numbers of SCI caused by trauma.
The typical person with SCI is 40 years old at the time of injury, but epidemiological details reveal a bimodal age distribution. The first peak is between 18 and 29 years and involves mainly men who are injured, while the second peak is at 65 years and above, when more women are affected.
Urological complications have historically been one of the most common causes of death after SCI. However, modern interventions and better management have reduced the rate to about 13%. Neurogenic lower urinary tract dysfunction after SCI is nevertheless still common, occurring in about 74-80% of patients.
Intermittent catheterization is now best practice for bladder management after SCI. Research highlights the fact that both bladder and bowel dysfunction need to be addressed after SCI, and there are interesting new study results suggesting benefits from different kinds of therapy options. For example, nerve stimulation may be a useful treatment option for bladder dysfunction, and there are good indications for bladder and bowel benefits associated with acupuncture. Bladder and bowel symptoms secondary to SCI have a great impact on quality of life for the people affected, and finding solutions is of the highest priority, regardless of the treatment method involved.

Review of worldwide epidemiological data of spinal cord injury (SCI) and associated neurogenic lower urinary tract dysfunction (NLUTD).
Spinal cord injury incidence varies from 12 to >65 cases per million people per year. Mean age at injury is 40 years, with incomplete tetraplegia as the most common outcome. SCI leads to NLUTD in 70-84% of cases.

Review on complications, surveillance techniques, and strategies for management related to neurogenic lower urinary tract dysfunction after spinal cord injury.
It is recommended that patients should undergo an annual check including physical examination, renal functional testing, and upper tract imaging. Routine cystoscopy or urodynamic is not recommended. Urologic complications are common and often complex.

Australian review and clinical practice guideline regarding bladder changes following spinal cord injury.
Intermittent catheterization is identified as best practice but there is a delay in introducing it after the acute phase of spinal cord injury. Differences are seen between hospital and community practice.

Observational survey evaluating the effect of sacral anterior root stimulation with sacral deafferentation (SARS-SDAF) on bladder and sexual dysfunction in 287 people with spinal cord injury.
SARS-SDAF showed good satisfaction with regard to bladder emptying but lower scores for sexual performance. SARS-SDAF seems to be able to reduce the need for catheterization, both intermittent and indwelling, in cases of involuntary urine leakage.

Review of the use of acupuncture in spinal cord injury.
Acupuncture seems to have an effect on motor and sensory dysfunction, pain, neurogenic bowel and bladder, pressure ulcers, spasticity, and osteoporosis. Physicians are recommended to consider it for management of complications related to spinal cord injury.

Observational retrospective study of urinary cultures in 146 patients with neurogenic bladder.
Urine cultures close in time are likely to include the same bacterial species. For example, there was 56% concordance but this decreased over time. Also, the concordance with susceptibility to antibiotics was high but did not differ over time.
Study suggesting benefits of monitoring previous urine cultures in people with neurogenic bladder. This may provide useful information about future susceptibility to organisms and antibiotics.

A retrospective review of 192 children with fecal incontinence attending a bowel management clinic, measuring their ability to achieve a regular bowel pattern and remain socially clean.
Children with spina bifida and Hirschprung’s disease preferred Peristeen and children with anorectal malformation and idiopathic constipation preferred Willis washout. The program was successful in 94% of cases.

Determination of anorectal physiology in an adult spina bifida cohort.
This study shows that fecal incontinence is correlated to rectum dysfunction rather than anal canal or external sphincter dysfunction.
Fecal incontinence in people with spina bifida is likely to be due to rectal abnormalities, which should be taken into consideration to improve treatments.

A cross-sectional phone survey with 64 patients with spinal cord injury. The survey assesses current bowel management methods, neurogenic bowel dysfunction (NBD) score, and a Likert scale questionnaire based on the International Classification of Functioning, Disability and Health (ICF) domains and quality of life (QoL).
There is a significant association between severity of NBD and negative QoL. The greatest impact from NBD was in personal and environmental factors in areas such as financial cost, need for assistance, emotional health, and loss of privacy.
