    Abstract:
    INTRODUCTION: Data on the long-term management of neurogenic bladder (NGB) are scarce. We evaluated the current status of NGB management in Japanese children over 24-month follow-up using the JMDC database. METHODS: In this descriptive, observational, retrospective cohort study, patients (≤ 17 years) with NGB were included. Patient characteristics and their management status were investigated. A multivariate analysis evaluating the potential risk factors for the development of urinary tract infection (UTI) was performed. The diagnosis of spina bifida, demographics, baseline comorbidities, and early use of clean intermittent catheterization (CIC) and/or overactive bladder (OAB) drugs were used as independent variables. RESULTS: Of 883 eligible children, 39.3% had spina bifida. Over 12/24-month post-index periods, renal urinary tract ultrasound and urinalysis were performed at least once in > 35%/> 45% patients, respectively, while specific tests (urodynamics, cystourethrography, scintigraphy) were performed in substantially fewer (< 11%/< 13%) patients. Over 24 months, 21.5% patients used OAB medications (mostly anticholinergics) and 10.8% underwent CIC, alone or with medications; 1.2% patients underwent surgery. Lower UTI (23.3%), urinary incontinence (9.7%), and hydronephrosis (7.0%) were the most common incident complications. Multivariate analysis evaluating risk factors for UTI showed significantly higher odds ratios with point estimates of ≥ 2 for CIC (5.70), presence of spina bifida (2.86), and constipation (2.07). Overall, urodynamic assessments were inadequately performed. CONCLUSION: Patients with use of CIC and/or having spina bifida and constipation had a higher risk of UTI, suggesting the need for careful follow-up. More guideline-compliant and diligent patient management is necessary in Japanese children with NGB.
