Abstract
OBJECTIVES Kidney failure is the main cause of morbidity and mortality in patients with myelodysplasia. We analysed the presence of renal lesions in these patients using dimercaptosuccinic acid scintigraphy and related their presence with the type of vesical function and the delay in receiving appropriate management. MATERIAL AND METHODS We performed a retrospective study of patients with myelodysplasia treated in our hospital since 2004. We analysed the epidemiological and clinical data and the pattern of bladder function according to urodynamic studies. We classified the patients into 4 urodynamic patterns according to detrusor and sphincter behaviour. We linked this behaviour to renal function in the scintigraphy and the care received since birth. RESULTS The study included 39 patients with myelodysplasia. The most common bladder pattern was type A (61.5%), with sphincter and detrusor hyperactivity, followed by type D (20.5%), C (7.8%) and B (5.1%). Some 38% of our patients (n=15) had some type of nephropathy. Some 92.9% of the children who were properly treated during the first year of their life had no renal lesions in the scintigraphy. We found some type of nephropathy in 56% of the patients for whom appropriate treatment was delayed for more than a year. The nephropathy was more severe the later the management was started. CONCLUSIONS There is a statistically significant relationship between a delay in treatment and impairment in renal scintigraphy in patients with neurogenic bladders. The early study and treatment of patients is essential for decreasing renal impairment, reducing the need for surgery and improving the continence options.

Evaluation of clinico-urodynamic outcome of bladder dysfunction after surgery in children with spinal dysraphism - a prospective study. Acta Neurochir (Wien) 2008; 150:129-37. [PMID: 18213439 DOI: 10.1007/s00701-007-1478-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2007] [Accepted: 11/06/2007] [Indexed: 10/22/2022]
Abstract
BACKGROUND The aim was to asses the clinical profile and urodynamic findings and the outcome of surgery in children with spinal dysraphism. METHOD Twenty five children with spinal dysraphism who were treated at our institute between January 2005 and June 2006 were studied prospectively. There were 10 with an open spina bifida and 15 closed. The clinical profile of bladder dysfunction was assessed and urodynamic evaluation done pre-operatively in each child. An ultrasound study of the kidneys was also done to assess for hydro-uretero-nephrois. All underwent surgery for their primary and associated malformations. Post-operatively, re-evaluation of bladder dysfunction and urodynamic parameters was performed at 6-8 months. RESULTS Before operation there was a history indicating that the bladder was involved in 14 of the 25 children. Six of the 10 cases with an open spina bifida showed clinical involvement of the bladder as compared to 8 of 15 with a closed pattern. Urodynamic studies showed evidence of bladder dysfunction in 19 children. Of 10 with a meningomyelocele, there were abnormal urodynamics in 9 as compared to 10 of 15 with closed dysraphism. Follow up urodynamic studies showed improvement in 9 of 20 children 3 of 7 with a meningomyelocele and 6 of 13 with closed dysraphism. CONCLUSION Children with open spina bifida, as compared to closed dysraphism, tend to have more bladder dysfunction as exemplified on clinical history and urodynamic assessment. A pre-operative urodynamic study helps to identify severity of bladder dysfunction which is clinically overt cases and also identifies subtle bladder dysfunction in clinically silent cases. Evaluation after operation tends to shows better outcome in children with closed dysraphism. The study also identifies deterioration in some patients with seemingly clinical improvement.

Abstract
The evaluation and treatment of children with neurogenic bladders can be difficult because of the complexity of the neurologic deficit and the subjectivity of the history and physical exam. The primary emphasis of the physicians caring for these children should be to preserve renal function and facilitate continence when possible. As knowledge of both normal and abnormal lower urinary-tract dynamics increases, so does the ability to care for children with abnormal bladder dynamics caused by various neurologic conditions. With recent advancements in medical and surgical treatment of the neurogenic bladder, most children can maintain adequate renal function and attain urinary continence. This article reviews the pertinent innervation, anatomy, and physiology of the lower urinary tract, and discusses current evaluation and treatment of children with neurogenic bladders.

Abstract
PURPOSE We determined which factors portend a higher risk of renal deterioration in the myelodysplastic child, and evaluated the sensitivity and predictive value. MATERIALS AND METHODS We retrospectively reviewed the medical history, imaging studies and urodynamics of 90 children with spinal dysraphism. Median patient age at initial evaluation was 3 months and average followup ranged between 2 and 25 years (average 11). We evaluated the relation of urodynamic parameters and sex to upper tract changes and the resolution of these changes. RESULTS Statistically significant relationships were identified between the urodynamic parameters of leak point pressure, compliance and detrusor-sphincter dyssynergia, and renal deterioration but not with resolution of deterioration. Boys and girls did not demonstrate a significant difference among urodynamic parameters. Female patients had a higher incidence of reflux and parenchymal loss. CONCLUSIONS With knowledge of the inherent sensitivity, specificity and predictive value of urodynamic parameters, selective use of urodynamics will assist in identifying patients at risk of renal deterioration. Female patients with reflux are at greatest risk of parenchymal loss. We advocate early institution of intermittent catheterization in patients identified as high risk for deterioration by urodynamics.

Abstract
We have adopted an approach to the management of myelodysplasia patients which is contrary to that most commonly supported by the existing literature. We screen patients shortly after birth with ultrasound, urine culture and serum creatinine, and then follow patients at 3 to 6-month intervals with similar studies. Cystography and urodynamics are done only as required clinically or by a change in the sonogram. Clean intermittent catheterization is indicated for continence or medical reasons. With this approach of aggressive observation and prompt intervention, we observed a rate of renal deterioration (diminished function on renal scan or parenchymal loss on imaging studies) of 5%. Renal deterioration was associated statistically with urinary tract infections and reflux. Patients started on clean intermittent catheterization for medical indications had greater risk for renal deterioration than those started on it for continence. Renal deterioration occurred with equal frequency between patients with abnormal and normal urodynamic studies, that is urodynamics did not predict renal deterioration. Our data show a rate of renal deterioration similar to other reports. We believe that aggressive observation with prompt intervention for problems once identified represents a reasonable alternative to managing patients with myelodysplasia.

Abstract
Between 1979 and 1990, 148 newborns with myelodysplasia were followed with serial urodynamic studies and neurological assessment. Of the patients 59 (40%) exhibited changes in neurological status by age 5 years, of whom 28 (19%) showed signs of deterioration. Most changes occurred before age 2 years. A total of 22 children underwent repeat neurosurgical exploration because of a change in urethral sphincter innervation (17), deterioration of function of the lower extremities (3), or changes on computerized tomography or magnetic resonance imaging (2). Postoperative urodynamic evaluation demonstrated improvement in 11 children, stabilization in 9 and further deterioration in 2. The earlier that a change was detected and secondary surgery was performed, the better the outcome. These findings indicate that the neurological lesion in myelodysplasia is a dynamic disease process requiring continuous neurological, orthopedic and urodynamic surveillance. Early identification and prompt neurosurgical reexploration seem to arrest and even reverse the neurological deterioration that takes place in a substantial number of these children.

Abstract
Recent reports have suggested that the prophylactic use of clean intermittent catheterization in selected infants with myelodysplasia and with normal upper tracts may prevent their deterioration. The selection of these patients at risk depends on urodynamic criteria. We reviewed our experience with clean intermittent catheterization instituted when upper tract deterioration was found. Of 130 patients with myelodysplasia followed at our clinic 25 (19%) had or presented with radiological upper urinary tract deterioration. A total of 21 patients had vesicoureteral reflux and 4 had hydronephrosis without reflux. Treatment consisted of clean intermittent catheterization alone in 5 patients and combined with anticholinergic medication in 16. Four patients with no post-void residual urine were carefully observed without intervention. Urodynamic evaluation was performed selectively in 11 of these 25 patients for persistence of upper urinary tract deterioration or urinary incontinence after institution of treatment. Of the 21 children with reflux 19 (90%) had resolution or improvement for an average followup of 47 months. Hydronephrosis completely resolved in the 4 patients without reflux. Thus, the over-all resolution or improvement rate was 92% for an average of 41 months. Although these excellent results may not be superior to the prophylactic use of clean intermittent catheterization, they validate the assumption that upper tract deterioration can be reversed. The application of current urodynamic selection criteria may result in overtreating a significant number of infants who otherwise may not have upper tract deterioration. Further refinements in these criteria may be necessary to select better not only patients at risk but also to determine the frequency of imaging necessary in this urologically heterogeneous population. In addition, careful consideration should be given to urethral dilation as a third and equally viable alternative to prevent upper tract deterioration.

Abstract
Hydronephrosis has been reported in 7 to 60 per cent of all newborns with myelomeningocele. However, most of these reports have been based upon x-ray findings obtained after closure of the myelomeningocele. To determine whether the radiographic abnormalities might be secondary to the neurosurgical procedure in a manner analogous to spinal shock, a prospective study of 34 newborns with myelomeningoceles was done during a 5-year period. Renal and bladder sonography was done on day 1 of life before surgical intervention and for varying periods thereafter. A total of 31 infants (91 per cent) had normal renal sonograms preoperatively but 6 of these had bilateral hydronephrosis and distended bladders postoperatively. Three patients had urinary retention before postoperative sonography could be obtained. For these 9 patients intermittent catheterization was required for 4 to 14 days until bladder tone recovered. Urinary retention in the infant with myelomeningocele may be a transient consequence of the myelomeningocele repair and should be treated conservatively for at least 2 weeks before surgical intervention is considered seriously.
