About 70% of these cases will self-resolve; however, symptomatic children may present with abdominal pain (i.e. Dietl crisis), vomiting, rash, or fever.</p><p><strong>Case presentation: </strong>A 14-year-old male patient presented with cyclical vomiting every two months for the past two years. The patient's mother also described an eight-year history of headaches and intermittent abdominal pain. A renal magnetic resonance urography scan revealed decreased right kidney function and delayed cortex to ureter transit time. A pyeloplasty and stent placement were performed to correct the obstructing vessel.</p><p><strong>Conclusion: </strong>Clinical guidelines for abdominal pain and cyclical vomiting earlier in the patients' healthcare may have led to an appropriate workup and treatment years before. We recommend physicians consider UPJO as a differential diagnosis in adolescent patients with cyclical vomiting and abdominal pain and consult the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHN) guidelines to better guide the diagnosis.</p>","PeriodicalId":520934,"journal":{"name":"Journal of pediatric nephrology..","volume":"11 4","pages":"214-219"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12240563/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
