Neurogenic Lower Urinary Tract Dysfunction in Adults with Cerebral Palsy: Outcomes following a Conservative Management Approach.

PURPOSE: Cerebral palsy is characterized by motor impairment following injury to the developing brain. Neurogenic lower urinary tract dysfunction is estimated to affect at least a third of children with cerebral palsy. However there are limited data as patients transition to adulthood. We sought to describe the symptoms, sequelae and management of neurogenic lower urinary tract dysfunction in adults with cerebral palsy. MATERIALS AND METHODS: We retrospectively reviewed the charts of adult patients with cerebral palsy between 2011 and 2014. Patients with prior bladder reconstruction or catheterization based bladder drainage were excluded from study. Cerebral palsy severity was determined using GMFCS (Gross Motor Function Classification System). A conservative evaluation and treatment paradigm was used. Noninvasive treatments were encouraged. Specifically clean intermittent catheterization, which is often not feasible, is avoided unless urinary retention, hydronephrosis or refractory lower urinary tract symptoms develop. RESULTS: There were 121 patients included in final analysis. Median age was 25 and 61 patients (50%) had GMFCS level V. Noninvasive management failed in 28 of 121 patients (23%) as defined by hydronephrosis in 9, persistent urinary retention in 10 and refractory lower urinary tract symptoms/incontinence in 9. Urethral clean intermittent catheterization was poorly tolerated. Of all patients 25% showed evidence of urolithiasis during the study period. Surgical intervention was rare and associated with significant morbidity. CONCLUSIONS: Adults with cerebral palsy may present with variable signs and symptoms of neurogenic lower urinary tract dysfunction. Conservative treatment was successful in more than 75% of patients. Clean intermittent catheterization was poorly tolerated in patients in whom conservative treatment failed. Surgical intervention was rarely indicated and it should be reserved for select individuals.

Factors associated with the Journal Impact Factor (JIF) for Urology and Nephrology Journals.

PURPOSE: The Journal Impact Factor (JIF) is an index used to compare a journal's quality among academic journals and it is commonly used as a proxy for journal quality. We sought to examine the JIF in order to elucidate the main predictors of the index while generating awareness among scientific community regarding need to modify the index calculation in the attempt to turn it more accurate. MATERIALS AND METHODS: Under the Urology and Nephrology category in the Journal Citations Report Website, the top 17 Journals by JIF in 2011 were chosen for the study. All manuscripts' abstracts published from 2009-2010 were reviewed; each article was categorized based on its research design (Retrospective, Review, etc). T and correlation tests were performed for categorical and continuous variables respectively. The JIF was the dependent variable. All variables were then included in a multivariate model. RESULTS: 23,012 articles from seventeen journals were evaluated with a median of 1,048 (range=78-6,342) articles per journal. Journals with a society affiliation were associated with a higher JIF (p=0.05). Self-citations (rho=0.57, p=0.02), citations for citable articles (rho=0.73,p=0.001), citations to non-citable articles (rho=0.65,p=0.0046), and retrospective studies (rho=-0.51,p=0.03) showed a strong correlation. Slight modifications to include the non-citable articles in the denominator yield drastic changes in the JIF and the ranking of the journals. CONCLUSION: The JIF appears to be closely associated with the number of citable articles published. A change in the formula for calculating JIF to include all types of published articles in the denominator would result in a more accurate representation.

Inaccuracy of Forefoot Axial Radiographs in Determining the Coronal Plane Angle of Sesamoid Rotation in Adult Hallux Valgus Deformity: A Study Using Weightbearing Computed Tomography.

BACKGROUND: Hallux abducto valgus is a triplane deformity with recent attention given to the significance of correcting the coronal plane component. This study explored the accuracy of the forefoot axial (FFA) study as a standard radiographic assessment method compared with weightbearing computed tomography (CT). METHODS: Twelve feet with hallux abducto valgus from 12 individuals were included in this study. Three images of the affected foot were taken: FFA radiograph and weightbearing CT with the foot in maximum pronation (pronated CT) and maximum supination (supinated CT). Five investigators determined the sesamoid rotation angles (SRAs) from each of the images. The measurements from a single investigator were used to compare the SRA means from each of the image types, and those from all five investigators were used to determine reliability. RESULTS: The mean ± SD SRA was 22.1° ± 7.6° for pronated CT, 10.5° ± 5.0° for supinated CT, and 12.2° ± 9.4° for FFA images. The mean SRA from the pronated CT was significantly greater than the supinated CT (P < .001) and FFA (P < .005) SRAs. There were no significant differences in mean SRA between the FFA and supinated CT images (P > .99). Results indicated high reliability in measurements among investigators. CONCLUSIONS: Using weightbearing CT, these findings indicate that the sesamoids significantly alter their position in the coronal plane, as determined by the SRA, with changes in weightbearing subtalar joint position. Moreover, the affected foot positioning required for determining the SRA from the FFA radiograph seems to significantly underestimate the true SRA. Thus, use of this image in surgical hallux abducto valgus planning is called into question.

Urologic problems in spina bifida patients transitioning to adult care.

OBJECTIVE: To identify the urologic needs of adult patients with spina bifida (SB) at the time of their transition from pediatric to adult care. We hypothesized that delays in transition to adult care would be associated with higher rates of active problems. METHODS: We retrospectively reviewed patients seen at adult dedicated SB clinics at the Universities of Utah and Minnesota from April 2011 to April 2012. We reviewed bladder management, urologic problems, time from last urologic care, and necessary interventions. RESULTS: We identified 65 patients from these clinics with SB. The mean age was 30.6 years (standard deviation, 11.3). The median time since last urologic evaluation at Utah and Minnesota was 17 months and 12 months, respectively (range 1 month-10 years). Fifty-five patients (85%) reported a urologic problem at the time of their visit. Urinary incontinence was most common in 34 (52%), followed by recurrent urinary tract infection in 22 (34%), catheterization troubles in 8 (12%), and calculi in 6 (9%). Sixty-three patients (97%) required some sort of intervention. These were diagnostic (cystoscopy, ultrasonography, computed tomography scan, urodynamics) in 50 patients (77%), surgical (urinary diversion, onabotulinum toxin A injection, stone surgery, and so forth) in 22 (34%), and medical (antimicrobial prophylaxis, bladder irrigations, anticholinergics, self-catheterization) in 16 (25%). There was no association between longer transition times and higher rates of active problems. CONCLUSION: On presentation to adult SB clinics, patients had many active urologic problems and operative management was often needed; however, there was no association between longer transition times and higher rates of active problems.
