Objective: To present our experience in a single pediatric urology practice over a 10-year period with bladder tumors in the pediatric population in an effort to add to the relatively small amount of existing data. We hope to expand the community's knowledge of presentations, management and natural history of pediatric bladder tumors.Methods: We retrospectively queried our electronic medical records for International Classification of Diseases, Tenth Revision (ICD-10) and Current Procedural Terminology (CPT) codes relevant for bladder tumors. Patients with underlying bladder pathology, such as neurogenic bladder, history of bladder exstrophy, and history of bladder augmentation, were excluded.Results: We identified 30 patients with bladder tumors from 2011 to 2021. There were 21 males and 9 females. Age at diagnosis ranged from 16 months to 19 years. Tumors identified were: 11 of various inflammatory subtypes; 4 papillomas; 4 rhabdomyosarcomas; 3 papillary urothelial neoplasms of low malignant potential and 8 of other types. Treatment included transurethral resection of bladder tumor, chemoradiation and laparoscopic partial cystectomy. Twenty nine patients had disease limited to the bladder and 1 had disease outside the bladder. Follow-up ranged from 2 weeks to 13 years (median 19 months). All patients had no evidence of disease at most recent follow-up.Conclusion: Pediatric bladder tumors range from aggressive rhabdomyosarcomas to more benign urothelial lesions. Fortunately, the latter type of tumor is the more prevalent lesion. Knowledge of the treatment options and natural history of these tumors will hopefully be of benefit to clinicians and parents alike. [ABSTRACT FROM AUTHOR]

Objective: To report the first exclusively pediatric series of robot-assisted urachal remnant excisions in children.Methods: We reviewed the medical records of all children who underwent robot-assisted excision of urachal remnants from 2010 to 2016. For the procedure, a 3-port approach was performed in all cases. Excision of the urachus was performed, along with partial cystectomy if there was clear or suspected bladder involvement. Outcomes and complications were reviewed.Results: Sixteen cases of robotic urachal excision were performed during the study period in patients aged 0.8-16.5 years. Complete excision was accomplished in all cases with no conversions. Partial cystectomy was performed in 11 cases, in which a urinary catheter was left for 1 day in all cases (no catheter was left in the absence of partial cystectomy). The only complication was a bladder leak requiring open surgical repair. There were no bowel injuries or hernias. The median operative time was 107 minutes. The length of stay was 2 days with partial cystectomy and 1 day without partial cystectomy. All patients were well at follow-up.Conclusion: We report the largest known series of robot-assisted urachal remnant excisions in children, demonstrating this minimally invasive approach to be safe and effective.

Objective: To examine trends in the number of cases of primary vesicoureteral reflux managed by ureteral reimplantation nationally over the last decade. Substantial changes have occurred in management of vesicoureteral reflux (VUR) over time, but trends in use of ureteral reimplantation have yet to be investigated on a national scale with annualized data.Materials and Methods: Using the Premier Healthcare Database, we extracted hospital discharge data for pediatric patients (age ≤ 18 years) with a procedure code for ureteroneocystostomy (International Classification of Diseases, Ninth Revision, 56.74) between January 1, 2003 and December 31, 2013. We excluded patients with secondary VUR. The presence of a temporal trend in reimplantation was examined via regression using generalized estimating equations.Results: In 4301 cases of primary VUR (23,602 weighted), there was a substantial decrease in the number of reimplantations performed, with an estimated decline in the rate of 0.239 cases per attending per year (P = .006). Average patient age declined 1.2 months in each year (P < .0001) due largely to a decline in reimplantation in those over age 2, which fell by 0.15 reimplantations per attending per year (P = .026). There was no difference between rates of decline in reimplantation for children with and without reflux nephropathy (P = .21) CONCLUSION: Nationally there has been a marked decrease in the incidence of ureteral reimplantation among children with primary VUR. The potential factors contributing to this are broad, including changes in diagnostic patterns, treatment recommendations, and the rise of endoscopic intervention. [ABSTRACT FROM AUTHOR]
