Significant advances in treatment for CF lung disease, including the expanded use of high-efficiency modulator therapies (HEMT) such as Trikafta, have dramatically increased both quality of life and life expectancy for people with CF (PwCF). With these advances, long-term extrapulmonary manifestations are more frequently recognized. Pseudo-Barter syndrome, acute kidney injury (AKI) induced by medications or dehydration, amyloidosis, nephrolithiasis, and IgA and diabetic nephropathies have been previously reported in PwCF. Newer data suggest that chronic kidney disease (CKD) is a new morbidity in the aging CF population, affecting 19% of people over age 55. CKD carries a high risk of premature death from cardiovascular complications. Studies suggest that CFTR dysfunction increases kidneys' vulnerability to injury caused by the downstream effects of CF. Improving the mutant CFTR function by HEMT may help to tease apart the kidney responses resulting from extrinsic factors and those intrinsically related to the CFTR gene mutations. Additionally, given the novelty of HEMT approaches, the potential off-target effects of their long-term use are currently unknown. We review the evolving kidney complications in PwCF and propose the term CF-related kidney disease. We hope this review will increase awareness about the changing phenotype of kidney dysfunction in PwCF and help prevent morbidity related to this condition.</p>","PeriodicalId":19735,"journal":{"name":"Pediatric Nephrology","volume":" ","pages":"3605-3614"},"PeriodicalIF":2.6,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649774","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}

In distinguishing benign from intermediate/malignant pathology using the mBosniak classification (I-II vs. III-IV), the overall pooled sensitivity, specificity, PPV, and NPV were 0.88 (227/257), 0.74 (82/111), 0.89 (227/256), and 0.73 (82/112), respectively. mBosniak III category showed a PPV of 0.78 (70/90) and mBosniak II category showed a NPV of 0.59 (36/61). From the perspective of pathological diagnoses, 0.24 (29/122) of the readings for intermediate-risk lesions inaccurately categorized the lesions as mBosniak I-II. The diagnostic performance of the classification varies among distinct subgroups of patients and lesion characteristics.</p><p><strong>Limitations: </strong>We included studies with pathologically verified lesions only. In addition, aspects of the radiographic follow-up, such as the duration of follow-up, changes in cyst complexity or size over time, and the correlation between specific dynamics and malignancy, could not be evaluated based on the data provided in the included studies.</p><p><strong>Conclusions and implications of key findings: </strong>The mBosniak classification is a less precise tool for stratifying the challenging cases of intermediate-risk lesions, and the relatively low predictive values of the middle categories (II-III) cast doubt on its utility. Clinicians should incorporate additional clinical-epidemiological data for a more accurate assessment of these lesions.
