However, their widespread application is accompanied by a high incidence of complications, each with potentially devastating consequences if left unrecognized. Encrustation and stone formation may result in obstruction, necessitating complex retrieval procedures. Stent migration can lead to severe discomfort, infection, and compromised renal function. Infection and pyelonephritis, if undetected, may progress to urosepsis, a life-threatening condition. Additionally, stent fracture and ureteral perforation can precipitate extensive morbidity, sometimes requiring surgical intervention. Given the critical nature of these complications, early detection through imaging is paramount. Radiologists play a pivotal role in diagnosing and characterizing these complications, ensuring timely management. By providing meticulous reporting of stent positioning, encrustation, migration, and associated pathologies, radiologists contribute to preventing severe adverse outcomes. A collaborative approach between urologists and radiologists is essential for optimizing patient care and mitigating the risks associated with prolonged stent placement.</div></div>","PeriodicalId":10695,"journal":{"name":"Clinical radiology","volume":"87 ","pages":"Article 106956"},"PeriodicalIF":2.1,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144230136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were classified into low- and high-risk groups (HRGs), and a survival prediction model was constructed. Model performance was evaluated with Kaplan–Meier curves, the log-rank test, and the C-index. GSEA identified gene sets associated with radiomic features linked to survival.</div></div><div><h3>RESULTS</h3><div>The Kaplan–Meier curve using the log-rank test (p&lt;0.01) and C-index values (0.768; 95% CI: 0.694–0.842) of the predictive models showed significant differences. GSEA was performed on the low- and HRGs, and the results identified a set of genes associated with cell proliferation, including the G2M checkpoint (p=0.006, FDR=0.138), mitotic spindle (p=0.006, FDR=0.156), and E2F targets (p=0.032, FDR=0.133).</div></div><div><h3>CONCLUSION</h3><div>This study revealed the biological functions underlying imaging features crucial for survival prediction and introduced an innovative approach to radiogenomics. This comprehensive approach promises to provide novel insights into the tumour microenvironment and potentially contribute to advancements in ovarian cancer treatment.</div></div>","PeriodicalId":10695,"journal":{"name":"Clinical radiology","volume":"86 ","pages":"Article 106952"},"PeriodicalIF":2.1,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144203099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
