Understanding the Connection: Spina Bifida and its Impact on Urinary Incontinence

Introduction

Spina bifida is a congenital anomaly that arises from incomplete development of the neural tube, leading to a range of physical and neurological challenges. It is often used as a nonspecific term to describe various degrees of neural tube closure, which can be further subdivided into spina bifida occulta and spina bifida aperta. Spina bifida occulta, or closed spinal dysraphism, is the mildest form of neural tube defects (NTD), involving a hidden vertebral defect with minimal neural involvement. In contrast, spina bifida aperta, or open spinal dysraphism, involves defects where neural tissues communicate with the external environment, as seen in conditions such as meningocele and myelomeningocele. These defects lead to a broad spectrum of neurological effects, depending on the degree of neural damage.

One of the most significant issues for individuals with spina bifida is urinary incontinence. Almost all children born with spina bifida develop a condition known as neurogenic bladder, caused by the improper formation of the spinal cord nerves that control bladder function. This results in difficulties with both urine storage and emptying, significantly impacting the individual’s quality of life.. This article will explore how spina bifida affects urinary health and provide insights on managing incontinence through various treatments and strategies

2. Prevalence and Complications of Spina Bifida

The complications of spina bifida vary depending on the severity of the defect. Common physical impairments include muscle weakness, mobility challenges, and abnormal posture, often requiring mobility aids like wheelchairs. Neurological problems are also prevalent, particularly in cases of myelomeningocele, where nerve damage may lead to bladder and bowel control issues, spasticity, and cognitive impairments. In more severe cases, additional complications such as seizures, endocrine disorders, and neurogenic bladder can further impact a patient's quality of life.

The prevalence of spina bifida varies globally, with a notable decline in incidence in recent years due to improved prenatal screening and folic acid supplementation. In the United States, the overall prevalence of spina bifida among children and adolescents aged 0 to 19 years was 3.1 cases per 10,000 in 2002. The prevalence tends to be lower among male children and non-Hispanic Black populations, with Hispanic children showing slightly higher rates. The overall prevalence of spina bifida in the U.S. from 1999 to 2007 was 3.17 per 10,000 live births.

Worldwide, Hispanic populations show a higher incidence, with a prevalence of 3.8 per 10,000 live births. Several factors influence these rates, including maternal health, genetics, and access to prenatal care, with increased risks for recurrence in families with a history of neural tube defects. Despite advances in prevention and early detection, there remain disparities in access to care, particularly in underserved communities, where screening and interventions may be limited.

Impact of Spina Bifida on Quality of Life

Spina bifida presents significant physical, psychological, and social challenges that profoundly affect the quality of life (QOL) for individuals. Physically, individuals with spina bifida often face mobility impairments that may require assistive devices such as wheelchairs. In a cohort study of 159 patients, 47% were able to ambulate in the community, while 36% were nonambulatory. Additionally, chronic pain and the need for multiple surgeries, including those for hydrocephalus and spinal deformities, are common. The need for surgical interventions, such as ventriculoperitoneal shunts (86% of patients with myelomeningocele), significantly affects physical health and contributes to lower health-related quality of life (HRQOL) scores. Patients with myelomeningocele reported significantly lower HRQOL scores compared to those with less severe forms of spina bifida, particularly in physical domains.

Psychologically, spina bifida impacts self-esteem and emotional well-being. Studies have shown that children and adults with spina bifida are at a higher risk of emotional and social difficulties. A significant portion of individuals report feelings of social isolation and difficulties in educational and social settings, with lower scores in emotional and social domains of HRQOL. Additionally, about 50% of individuals with myelomeningocele also suffer from impaired bowel continence, which further affects their psychological well-being and HRQOL.

Social and financial challenges are also major factors. The cost of healthcare for ongoing treatments, surgeries, and rehabilitation can be overwhelming. For instance, a history of complex procedures such as Chiari malformation decompression was associated with worse overall HRQOL scores, particularly in speech and cognition domains. The long-term care required for individuals with spina bifida places a significant financial and emotional strain on families. The added burden of managing urinary incontinence, a common issue due to neurogenic bladder, further compounds these challenges, affecting both physical and emotional quality of life.

Understanding Urinary Incontinence in Spina Bifida

Urinary incontinence in spina bifida (SB) is primarily caused by neurological damage that disrupts normal bladder function. The condition stems from a defect in the closure of the neural tube, which leads to impaired spinal cord and nerve development. The most severe form, myelomeningocele (MMC), is often associated with significant damage to the spinal cord. This damage interferes with the nerves that control bladder function, leading to a range of bladder dysfunctions such as detrusor overactivity, underactive bladder, and sphincter dysfunction.

Detrusor overactivity, a common issue in Spina Bifida patients, occurs when the bladder muscles contract involuntarily, leading to urgency and incontinence. This is seen in up to 42% of patients with the cystic form of Spina Bifida. Conversely, underactive bladder refers to a reduced ability to empty the bladder fully, which can lead to urinary retention and high post-void residuals. A study by Sakakibara et al. found that low bladder compliance was present in 81% of MMC patients, significantly impairing their ability to store urine.

Other factors contributing to urinary incontinence in SB include the severity of the spinal defect, age, and co-existing conditions like Chiari malformation or hydrocephalus. In fact, up to 61% of young adults with SB experience urinary incontinence. The presence of conditions like tethered cord syndrome (TCS), which affects 10-30% of SB patients, can further worsen bladder control. As a result, many individuals with SB require ongoing interventions, including catheterization or surgeries, to manage their urinary dysfunction and prevent further renal complications, such as vesicoureteral reflux, which occurs in up to 40% of children with Spina Bifida.

Management of Urinary Incontinence in Spina Bifida

Managing urinary incontinence in patients with spina bifida (SB) often involves a combination of non-surgical and surgical approaches. Clean intermittent catheterization (CIC) is a cornerstone of conservative treatment, helping to empty the bladder reliably and reduce high intravesical pressure, which can lead to further kidney damage. Pharmacologic treatments, such as anticholinergic medications are commonly used to manage detrusor overactivity (DO), a common issue in Spina Bifida patients. In some cases, botulinum toxin injections can be used to suppress bladder contractions and improve bladder function for several months.

When medical management is insufficient, surgical options may be necessary. Bladder augmentation and bladder outlet procedures are common surgical interventions aimed at improving bladder capacity and reducing incontinence. For patients who cannot manage with CIC, creating a catheterizable channel is another option.

Lifestyle modifications, including adequate hydration and dietary changes, play a crucial role in bladder health. Regular monitoring and adjustments to these treatment plans are essential as patients grow older, and the risk of renal deterioration increases.

Why Absorbent Pads are Necessary for Patients with Spina Bifida and Urinary Incontinence? 

A survey of 109 patients with spina bifida revealed mixed results in managing bladder and bowel control. Of those who had undergone urinary diversion, 71% were reliably dry, while only 38% of those using other bladder emptying methods, like CIC or indwelling catheters, achieved dryness. Only 24% of patients were both reliably clean and dry. These results emphasize the need for comprehensive management, including medical treatments and practical solutions like absorbent pads.

Managing urinary incontinence in patients with spina bifida (SB) can be challenging, particularly due to mobility limitations or difficulty accessing bathrooms. Absorbent pads provide a crucial solution by offering comfort, protection, and dignity for patients experiencing incontinence. These pads help manage leakage and reduce the risk of skin damage caused by prolonged exposure to moisture, which is a common concern for individuals with limited mobility.
