MR cisternography was useful for evaluating patients with rhinorrhea and suspected CSF fistula. It depicted the fistula site in most patients. No adverse effects were found in any patient.

Introduction. Major Outpatient Surgery (MOS) is an organizational and management model for surgical care that allows selected patients to be treated efficiently and safely. Our objective was to evaluate the quality of the different activities through standardized quality indicators, analyzing whether they have been modified during the COVID-19 pandemic.Materials and methods. An observational and comparative descriptive study of the quality indicators (QI) of MOS in our Pediatric Surgery Department from 2019 to 2020 was carried out. In accordance with the International Association for Ambulatory Surgery (IAAS) and the recommendations of the Spanish Ministry of Health and Consumer Affairs, we assessed the basic quality and the degree of family satisfaction of patients undergoing MOS.Results. A total of 848 and 652 interventions were performed in 2019 and 2020, respectively, with a mean age of 6 and 7 years. 539 (ambulatory rate (AR) 63.6%) and 465 (AR 71.3%) MOS surgeries were conducted in 2019 and 2020. In 2019, the overall substitution rate (SR) was 96.8%, hospitalization rate (HR) was 1.67%, suspension rate was 5.94%, and readmission rate was 1.48%. In 2020, the overall IS was 98.3%, HR was 0.86%, suspension rate was 4.73%, and readmission rate was 1.72%. No differences were found in terms of satisfaction between 2020 and 2019.Conclusions. QI allow us to know and analyze the performance and results of the different management units. In our department, the COVID-19 pandemic has not reduced the quality of CMA care.

Introduction. Congenital nephrourological abnormalities (CAKUT) are a particularly relevant group of diseases due to their high prevalence and the fact they are the main cause of chronic renal disease (CRD) in the pediatric population. Our objective was to determine the characteristics and prevalence of CAKUT in our setting, while identifying the factors associated with the occurrence of renal damage.Materials and methods. A retrospective, descriptive, analytical, cross-sectional study of patients seen in the Pediatric Nephrology Department of a third-level hospital from January 1 to December 31, 2018 was carried out. Epidemiological, clinical, and analytical variables were assessed, and potential risk factors associated with CRD were searched for.Results. The study involved 685 patients with 827 kidney units affected by CAKUT with a mean age of 9.98 ± 5.12 years. 62.2% were male, and the mean follow-up period after diagnosis was 9.95 ± 5.09 years. 58.8% were non-obstructive dilations, followed by renal dysplasia, obstructive dilations, and number and position abnormalities. The most frequent malformation was vesicoureteral reflux (VUR). The most commonly affected side was the left (47.5%). 55% of the diagnoses were prenatal. 172 patients underwent surgery. The initially chosen treatment for VUR was endourological. Overall re-intervention rate was 20%. Of the total number of patients, glomerular filtration rate was analyzed in 383, 95 (24.8%) of whom had CRD (86% in stage 2). Male sex, bilaterality, and proteinuria were risk factors associated with CRD.Conclusions. Knowledge of the epidemiological and clinical characteristics of children with CAKUT and the factors associated with CRD helps to individualize the clinical follow-up of these patients, thus customizing diagnostic tests and healthcare resources.
