After 6 months of follow-up, the TRACK score was improved in both groups, and the "Ti ≥ 60 group" had a higher score, lower rate of uncontrolled asthma and fewer reassessments were required. There was no difference in the number of wheezing attacks between the two groups in terms of clinical presentation, but the "Ti less then 60 group" had more respiratory infections and ED visits. Regarding the use of ICSs, in the "Ti less then 60 groups," the dose of ICSs was higher and reduced slowly, and the dose difference between the two groups began to appear after 5 months of follow-up. Conclusion TRACK is essential for pre-schoolers with asthma at the time they are diagnosed. In addition, if the TRACK initial score is less then 60, the probability of poor prognosis is higher.Objective To investigate surgical techniques and challenges of laparoscopic in treating pediatric ureteral polyps under laparoscopy. Methods The clinical data of 7 of pediatric ureteral polyps patients who were admitted to the hospital from July 2015 to January 2020 were analyzed retrospectively. There were 6 males and 1 female from 7.7 to 13.9 years old at the mean age of 10.4. Before surgery, all children performed urinary B ultrasound, magnetic resonance urography (MRU), and renal radionuclide scanning. Six cases were observed on the left lateral and 1 on the right. The lesions of 5 cases were located at the ureteropelvic junction, 1 in the upper ureter and 1 in the middle ureter. The polyps were treated intraoperatively by the resecting of the lesion segment and simple polypectomy to retain the attached part of the original diseased segment of the ureter. All surgeries were performed under laparoscopy and B-ultrasound was performed during follow up after surgery. Results All 7 surgeries were performed suctomosis.Children with disabilities compose a substantial portion of admissions and bed-days in the pediatric intensive care
