Obstetric ultrasonography increased the detection of primary megaureters (PM); the most common type is non-refluxing, with a tendency to spontaneous resolution. Objectives. To determine predictors and time to spontaneous resolution and incidence of urinary tract infection (UTI) with and without antibiotic prophylaxis (AP). Population and methods. Retrospective cohort. The PM was defined as an anteroposterior diameter (APD) of the retrovesical ureter ≥7 mm, with or without pelvic dilatation (≥10 mm), at the first postnatal ultrasound. Spontaneous resolution was the absence of dilatation or a ureter APD <7 mm and pelvis <10 mm. Results. Seventy patients presented with PM, 15 bilateral. Of the 85 PM, 53 (62%) resolved spontaneously. In these patients, the ureter and pelvic APD at the first postnatal ultrasound were lower than those requiring surgery (p = 0.0001). A ureteral APD ≥10 mm and pelvic APD ≥15 mm increased the risk of surgery 2.63 and 4.57 times, respectively. The median time to spontaneous resolution was 6 and 33 months for ureters with APD < or ≥10 mm (p = 0.009) respectively. The incidence of UTI in the first year was 0.21. There were 7/22 children with AP and 7/44 without AP. Conclusion. Two-thirds of the MPs resolved spontaneously in a median of 6 months, with ureter and pelvic APD at birth being predictors.

The pediatric postural balance scale (PBS) is a valuable clinical tool for assessing postural balance in preschool and school-aged children with typical or atypical development. Objective. To assess the PBS's concurrent validity and inter-rater reliability in Chilean preschoolers and schoolchildren with typical development. Population and methods. Two hundred and three preschool and school children aged 4 to 11 (7.6 ± 2.1 years, 56.2% males) from public and private schools participated in a cross-sectional validation study. Postural balance was evaluated with PBS and postural oscillography, considering maximum lateral velocity (MLV), maximum anteroposterior velocity (MAPV), mean total velocity (MTV), mean radius (MR), and center of pressure area (COP area). Anthropometric parameters and socioeconomic level were measured. Results. The inter-rater reliability for the PBS with the intraclass correlation coefficient was 0.99 (95%CI: 0.990-0.997). There were weak inverse correlations between PBS total score and oscillography (MLV, MAPV, MTV, MR, and COP area) in the 4- to 6-year age group, standing out the correlations of mean radius (rho: -0.36; p 0.002) and COP area (Rho: -0.37; p 0.001). Conclusion. These results suggest that the PBS provides a very strong inter-rater reliability and a weak inverse correlation between the PBS total score and postural oscillography measures in the 4- to 6-yearold age group. Therefore, using PBS is recommended primarily in preschoolers and school children between 4 and 6 years of age.</p>","PeriodicalId":8338,"journal":{"name":"Archivos argentinos de pediatria","volume":" ","pages":"e202410276"},"PeriodicalIF":0.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
