The urological management of children with spinal cord injury

Causes and management of urinary system problems in children on long-term home invasive mechanical ventilation

Many ventilator-dependent children have comorbid conditions including urinary tract disorders. We aimed to present a focused review of the literature describing the causes and management of urinary system problems in children with long-term home mechanical ventilation. We performed a literature search in PubMed/MEDLINE, Scopus, and Web of Science with keywords "children," "home mechanical ventilation," "urinary system," "urinary tract," "neurogenic bladder," "clean intermittent catheterization," "urinary tract infection," "urolithiasis," and "acute kidney injury." We included original articles, reviews, guidelines, and case reports published in English. Ventilator-dependent children may have neurogenic bladder/bowel dysfunction which renders them prone to urinary tract infection, high bladder pressure, vesicoureteral reflux, hydronephrosis, and renal dysfunction. These children require bladder catheterization, medications affecting parasympathetic/sympathetic nervous systems, or surgical procedures to prevent urinary infections, and to maintain continence and renal functions. However, bladder catheterization or surgical procedures like augmentation cystoplasty may also be complicated with urinary infections, urolithiasis, or urethral strictures. Urolithiasis frequency is also increased due to immobilization-related hypercalciuria, hypocitraturia caused by antiepileptic drugs, urinary stasis, and urinary infections. On the other hand, mechanical ventilation can impair renal function by reduction of cardiac output, redistribution of intrarenal blood flow and stimulation of sympathetic and hormonal pathways. Children requiring long-term invasive home mechanical ventilation may have other comorbid conditions, including urinary system diseases, which become manifest as these patients are being kept alive due to the advances in ventilation strategies. These children must be carefully observed for urological complications and managed accordingly to prevent kidney injury.

Neurocritical care and neuromonitoring considerations in acute pediatric spinal cord injury

Management of pediatric spinal cord injury (SCI) is an essential skill for all pediatric neurocritical care physicians. In this review, we focus on the evaluation and management of pediatric SCI, highlight a novel framework for the monitoring of such patients in the intensive care unit (ICU), and introduce advancements in critical care techniques in monitoring and management. The initial evaluation and characterization of SCI is crucial for improving outcomes as well as prognostication. While physical examination and imaging are the main stays of the work-up, we propose the use of somatosensory evoked potentials (SSEPs) and transcranial magnetic stimulation (TMS) for challenging clinical scenarios. SSEPs allow for functional evaluation of the dorsal columns consisting of tracts associated with hand function, ambulation, and bladder function. Meanwhile, TMS has the potential for informing prognostication as well as response to rehabilitation. Spine stabilization, and in some cases surgical decompression, along with respiratory and hemodynamic management are essential. Emerging research suggests that targeted spinal cerebral perfusion pressure may provide potential benefits. This review aims to increase the pediatric neurocritical care physician's comfort with SCI while providing a novel algorithm for monitoring spinal cord function in the ICU.

Pediatric spinal cord injury with radiographic abnormality: the Beijing experience

BACKGROUND CONTEXT

Spinal cord injury (SCI) without radiographic abnormality (SCIWORA) is a syndrome that usually occurs in children primarily because of the unique biomechanics of the pediatric spine. We recently found that the histopathological and behavioral effects of SCI with radiographic abnormality (SCIWRA) and SCIWORA are very different from each other in animal models. Although numerous studies were conducted to understand the epidemiological and clinical characteristics of the overall pediatric SCI population and the pediatric SCIWORA population, the characteristics of the pediatric SCIWRA population and their differences from those of the SCIWORA population are poorly understood.

PURPOSE

To describe the epidemiology and clinical outcomes of pediatric patients with SCIWRA and their differences from those with SCIWORA.

STUDY DESIGN/SETTING

Retrospective study.

PATIENT SAMPLE

A total of 47 pediatric SCIWRA patients.

OUTCOME MEASURES

Epidemiological characteristics, injury severities, functional deficits, and management and recovery outcomes.

METHODS

Review of all cases with SCIWRA at Beijing Children's Hospital between July 2007 and December 2019 and comparison between the present data and our previous SCIWORA data.

RESULTS

Of the 187 pediatric SCI patients, 47 had SCIWRA (age: 7.06 ± 3.75 years, male-to-female ratio: 3:2). Main causes of SCIWRA were fall (38%) and traffic accidents (38%). Lesions were often located at multiple levels (62%). Incubation period was 3 ± 18 hours. According to the American Spinal Injury Association impairment scale (AIS), many SCIWRA patients had incomplete impairment (AIS B, 9%; AIS C, 9%; AIS D, 32%). Specifically, many of them had abnormal upper and lower limb muscle powers (55% and 60%), upper and lower limb muscle tones (34% and 49%), sensation (38%), and knee, ankle, and abdominal reflexes (47%, 34%, and 36%). 72% of SCIWRA patients were treated with methylprednisolone, dexamethasone, or both. 81% of them showed neurological improvement before discharge. There was no association between corticosteroid therapy and neurological improvement. Moreover, functional outcomes of their upper and lower limb muscle powers were significantly associated with functional outcomes of their upper and lower limb muscle tones (p < 0.01), respectively. In comparison to the SCIWRA population, the SCIWORA population had a higher ratio of younger and female patients of sports-related thoracic injuries with long incubation period leading to lower-body deficits and complete impairment (p<0.05 or p<0.01). Despite all the differences, their neurological improvement was similar (p>0.05).

CONCLUSIONS

Demographic differences exist in the SCIWRA population. Corticosteroids do not appear to be effective in the different types of pediatric SCI. Limb muscle tone may be used to evaluate the functional status of limb muscle power. The epidemiological and clinical characteristics of SCIWRA and SCIWORA are very different from each other. It is important to formulate tailor-made prevention, evaluation, and management strategies for the pediatric population to optimize the SCI outcomes.

Prognosis of traumatic spinal cord injury in children: Follow-up of 86 patients

PURPOSE

The long-term situation of children with spinal cord injury (SCI) was investigated, and suggestions for helping them better return to the society were provided.

METHODS

SCI patients less than 18 years old hospitalized in Beijing Boai Hospital from January 2011 to December 2020 were retrospectively analyzed. Information including motor function, complications, characteristic changes, self-care abilities, school attendance and social participation were collected by telephone interview and electronic questionnaire. All the answers were statistically analyzed.

RESULTS

A total of 86 cases were enrolled, 77 girls and 9 boys, with a median injury age of 6 years and 2 months. The follow-up time was 3-130 months. The main cause of trauma in these children was sport injury (66.3%), the thoracic spinal cord was involved the most (91.9%), and complete SCIs accounted for the majority (76.7%). In terms of complications, children with complete SCIs were more likely to have urinary incontinence, constipation and characteristic changes (p < 0.05); whereas the incomplete SCIs often have spasticity (p < 0.05). As to the daily living abilities, children with incomplete lumbar SCIs were more capable to accomplish personal hygiene, transfer, and bathing independently than those with complete injuries, or cervical/thoracic SCIs, respectively (p < 0.05). Moreover, children older than 9 years care more able to dress and transfer independently than the youngers (p < 0.05). Wheelchair users accounted for 84.9% and more than half of them were able to propel wheelchair independently, and those who move passively in wheelchairs were mostly introverted kids (p < 0.05). Almost all (93.8%) children with incomplete injuries were able to walk independently. Most (79.1%) children continued to attending school, and 41.9% participated in interest classes. Unfortunately, 67.4% of the children spent less time playing with their peers than before the injury.

CONCLUSION

SCIs impair physical structures and function of children, affect their independence in daily living, and restrict school attendance and social interaction. Comprehensive rehabilitation after injury is a systematic work. Medical staff and caregivers should not only pay attention to neurological function, but also help them improve self-care abilities. It is also important to balance rehabilitation training and school work and social participation.

Evidence-based position paper of the UEMS PRM on the role of Physical and Rehabilitation Medicine (PRM) physician in the management of children and adults with spinal dysraphism

Spinal dysraphism (SD) or spina bifida (SB) is a congenital deformity that results from embryonic neural tube closure failure during fetal development. This evidence-based position paper represents the official position of the European Union through the UEMS PRM Section. This paper aims to evaluate the role of the physical and rehabilitation medicine (PRM) physician and PRM practice for children and adults with spinal dysraphism. A systematic literature review and a consensus procedure involved all European countries delegates represented in the UEMS PRM section through a Delphi process. The systematic literature review is reported together with thirty-two recommendations resulting from the Delphi procedure. The professional role of the PRM physician requires specific expertise in the treatment of patients with SD to plan, lead and monitor the rehabilitation process in an interdisciplinary setting and to participate in the assessment of the needs of these patients in the transitional phase from childhood to adulthood, with particular attention to the activity limitation and participation restriction.

Pediatric Spina Bifida and Spinal Cord Injury

Pediatric spina bifida (SB) and spinal cord injury (SCI) are unfortunately common in our society, and their unique findings and comorbidities warrant special consideration. This manuscript will discuss the epidemiology, pathophysiology, prevention, and management strategies for children growing and developing with these unique neuromuscular disorders. Growth and development of the maturing child places them at high risk of spinal cord tethering, syringomyelia, ascending paralysis, pressure injuries, and orthopedic abnormalities that must be addressed frequently and judiciously. Similarly, proper neurogenic bladder and neurogenic bowel management is essential not just for medical safety, but also for optimal psychosocial integration into the child’s expanding social circle.

Pharmacologic and Acute Management of Spinal Cord Injury in Adults and Children

Purpose of Review

This review provides guidance for acute spinal cord injury (SCI) management through an analytical assessment of the most recent evidence on therapies available for treating SCI, including newer therapies under investigation. We present an approach to the SCI patient starting at presentation to acute rehabilitation and prognostication, with additional emphasis on the pediatric population when evidence is available.

Recent Findings

Further studies since the Surgical Timing in Acute Spinal Cord Injury Study (STASCIS) demonstrated a potential functional outcome benefit with ultra-early surgical intervention ≤ 8 h post-SCI. Subsequent analysis of the National Acute Spinal Cord Injury Study (NASCIS) II and NASCIS III trials have demonstrated potentially serious complications from intravenous methylprednisolone with limited benefit. Newer therapies actively being studied have demonstrated limited or no benefit in preclinical and clinical trials with insufficient evidence to support use in acute SCI treatment.

Summary

Care for SCI patients requires a multi-disciplinary team. Immediate evaluation and management are focused on preventing additional injury and restoring perfusion to the affected cord. Rapid assessment and intervention involve focused neurological examination, targeted imaging, and surgical intervention when indicated. There are currently no evidence-based recommendations for pathomechanistically targeted therapies.

Health and LifeDomain ResearchPriorities in Children, Adolescents and Young Adults With Pediatric-Onset Spinal Cord Injury: A National Cross-Sectional Survey in England

Background

Although feedback from people with adult-onset spinal cord injury (SCI) has been considered in developing research programs, little is known about pediatric-onset SCI priorities.

Objectives

To describe the health and life (H&L) domain research priorities of youth with pediatric-onset SCI living in England.

Methods

Youth with pediatric-onset SCI (≥6 months) were recruited from five English rehabilitation centers and invited with their parents/caregivers to complete the age-appropriate surveys designed by the Pan-European Paediatric Spinal Cord Injury (PEPSCI) collaboration.

Results

A total of 73 surveys were received (32 from participants with SCI and 41 from their parents/caregivers), providing information on 47 individuals with SCI: 2- to 7-year-olds (29.8%), 8- to 12-year-olds (19.2%), 13- to 17-year-olds (17.0%), and 18 to 25-year-olds (34.0%). The top three research priorities reported by parents/caregivers of 2- to 12-year-old and 13- to 25-year-olds were pain (81%/89%), physical function (91%/83%) and health care access (78%/78%). Eighty-nine percent of 8- to 12-year-olds emphasized schooling, peer relationships, and general mood as their research priorities. The top three research priorities for Health or Life domains reported by 13- to 25-year-olds included spasms (95%), pain (91%), pressure injuries (91%), health care access (83%), physical function (78%), and daily personal needs (74%).

Conclusion

Although there should be an emphasis on addressing important life domain issues for 8- to 12-year-olds with SCI, adolescents and young adults mostly prioritized health domain research priorities in addition to health care access. This survey will aid health care and clinical research organizations to engage stakeholders to implement a comprehensive SCI research strategy in England for the pediatric population.

Risk factors predicting upper urinary tract deterioration in children with spinal cord injury

AIM

The aim of this study is to determine the risk factors predicting upper urinary tract (UUT) deterioration in children with spinal cord injury (SCI).

METHODS

The medical records of 108 children with SCI who were referred to our unit between 1996 and 2018 were retrospectively reviewed. The data included general patient demographics, SCI characteristics, bladder management methods, presence of urinary tract infection, radiological evaluation of the UUT and lower urinary tract (LUT), and videourodynamic findings. The receiver operating characteristic (ROC) curve analysis was performed to determine the cutoff values of the maximum detrusor pressure during filling and the bladder volume ratio (BVR) for predicting UUT deterioration. Multivariate analyses were used to determine the risk factors predicting UUT deterioration.

RESULTS

Complete data were available for 76 children. The median patient age was 15 years (2-17). The leading causes of SCI were motor vehicle accidents (44%) and fall (33%). UUT deterioration was identified in 33 patients (43%). Iatrogenic SCI etiology, abnormal radiological LUT findings, and detrusor pressures greater than 70 cmH₂ O were found to be independent risk factors for UUT deterioration using regression analysis. In addition, ROC analysis revealed that a BVR less than 0.7 was the cutoff value for UUT deterioration in children with SCI.

CONCLUSION

Abnormal radiological LUT findings, iatrogenic SCI etiology, detrusor pressure greater than 70 cmH₂ O, and a BVR less than 0.7 were independent risk factors for UUT deterioration in children with SCI.

Medical Management of Neurogenic Bladder for Children and Adults: A Review

Neurogenic bladder is a chronic condition affecting patients of all ages with significant medical and quality of life implications. Goals of treatment consist of protection of the upper urinary tract and promotion of reliable urinary continence. Successful management involves medications and most often bladder drainage via clean intermittent catheterization. This article reviews current literature on medical management to achieve goals of treatment.

Our experience with ureterocystoplasty in bilateral functional kidneys

OBJECTIVE

We have reviewed the data of the patients in order to evaluate the effectiveness of our ureterocystoplasty technique in augmentation cystoplasty operation.

MATERIAL AND METHODS

Data of a total of 16 patients with bilateral functional kidneys who had undergone augmentation ureterocystoplasty between January 1995 and June 2018 which were retrieved during the retrospective archive scanning were included in the study. Ultrasonography (USG), serum blood urea nitrogen and creatinine values and Technetium-99 DTPA (Tc-99 DTPA) scan were used to evaluate the renal function of the patients. Intravenous pyelography (IVP) and USG were used to evaluate the ureters before surgery. Magnetic resonance (MR) urographies were performed in our center.

RESULTS

Of the total 16 patients, 10 were male and 6 were female, while ages ranged from 1 to 24 years. Among 16 patients, the most common cause of neurogenic bladder etiology was meningomyelocele. In the urodynamic studies performed before the operation, it was determined that the bladder capacities of the patients were between 40-180 mL and the bladder compliances were 1.0-4.0 cc/cmH₂O. At postoperative 3^rd months, it was determined that the bladder capacities of the patients were between 180-330 mL and the bladder compliances were between 6.0-24.0 cc/cmH₂O.

CONCLUSION

Augmentation ureterocystoplasty seems to be an appropriate technique in which successful results are obtained with appropriate patient selection. Besides, complications that may occur due to use of ileal segment are avoided.
