Neurogenic Bladder Dysfunction as Signal of Late Failure of Endoscopic Third Ventriculostomy in Child with Spina Bifida

OBJECTIVE: This study aimed to develop and validate a practical nomogram to predict the occurrence of post-traumatic hydrocephalus in patients who have undergone decompressive craniectomy for traumatic brain injury. METHODS: A total of 516 cases were enrolled and divided into the training (n=364) and validation (n=152) cohorts. Optimal predictors were selected through least absolute shrinkage and selection operator regression analysis of the training cohort then used to develop a nomogram. Receiver operating characteristic, calibration plot, and decision curve analysis, respectively, were used to evaluate the discrimination, fitting performance, and clinical utility of the resulting nomogram in the validation cohort. RESULTS: Preoperative subarachnoid hemorrhage Fisher grade, type of decompressive craniectomy, transcalvarial herniation volume, subdural hygroma, and functional outcome were all identified as predictors and included in the predicting model. The nomogram exhibited good discrimination in the validation cohort and had an area under the receiver operating characteristic curve of 0.80 (95%CI 0.72-0.88). The calibration plot demonstrated goodness-of-fit between the nomogram's prediction and actual observation in the validation cohort. Finally, decision curve analysis indicated significant clinical adaptability. CONCLUSION: The present study developed and validated a model to predict post-traumatic hydrocephalus. The nomogram that had good discrimination, calibration, and clinical practicality can be useful for screening patients at a high risk of post-traumatic hydrocephalus. The nomogram can also be used in clinical practice to develop better therapeutic strategies.

Hydrocephalus is the most important co-morbidity in myelomeningocele from a neurosurgical perspective. Historically, 75-80% of patients with myelomeningocele have required treatment with a shunt but recent advances including intra-uterine myelomeningocele closure and ETV-CPC are reducing this burden. The expression of hydrocephalus differs between patients and across the life span. Hydrocephalus impacts the clinical expression of other important co-morbidities including the Chiari II malformation and tethered spinal cord. Shunt failure is often the key stress to prompt symptomatic worsening of these other conditions. Shunt failure may occur with minimal ventricular change on CT or MRI in Spina Bifida patients. Waiting for radiographic changes in symptomatic SB patients with shunts may result in hydrocephalus related fatalities. It is hypothesized but not proven that shunt failure may contribute to respiratory insufficiency and be a risk factor for sudden death in adult patients with spina bifida. Excellence in hydrocephalus management in MMC is essential for proper care, good outcomes, and quality of life for patients and families.
