Background Image‐guided fine needle aspirations (FNAs) and core needle biopsies (CNBs) play the critical role in diagnosis of renal lesions. Rapid on‐site evaluation (ROSE) can potentially increase the adequacy rate and improve diagnostic yield, while providing additional information for rapid clinical decisions. The aim of this study is to evaluate the diagnostic utility of ROSE in obtaining adequate tissue for diagnosis of renal lesions in our institution. Methods We retrospectively reviewed all percutaneous renal CNB cases with available ROSE interpretations for a 11‐year period. The ROSE interpretations and CNB diagnoses was compared and the concordance rate was calculated accordingly. The discrepant cases were re‐reviewed and the possible causes for discrepancy were analyzed. Results A total of 189 cases were identified. Definitive diagnoses were rendered in 164 (87%) cases on the final CNBs, including primary renal lesions in 151 cases and metastatic malignancies in 13 cases. At the time of ROSE, samples were deemed to be adequate in the majority of cases (83%). The calculated concordance rate between ROSE interpretations and CNB final diagnoses was 84.6%. Sampling issue and scant tumor cells were the main causes for the discordance between ROSE interpretations and CNB diagnoses. Conclusion Our study showed a relatively high‐concordance rate of 84.6% between ROSE interpretations and CNB final diagnoses, suggesting that ROSE is a valuable tool for procurement of adequate renal CNB samples for diagnosis.

and hospital charges using STATA 17. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results: We identified 1,198,839 patients with IBD of which 235,880 patients were matched to those with anxiety. Average age was 52.04 years. There was a significant decrease in inpatient mortality (OR 0.56, CI 0.51-0.62, P , 0.0001) and total cost of hospitalization (-$3,242.13, CI -4,259.55 --2224.70, P , 0.0001), but hospital length of stay increased (0.27 days, CI 0.20-0.34, P , 0.0001) between patients with IBD with cannabis use when compared to IBD patients without cannabis use. Conclusion(s):The different clinical manifestations and symptoms of IBD may cause several psychological changes in patients. Past studies demonstrated that psychological stress and disorders can trigger flares and relapses in patients with IBD. Our study showed that there was a statistically significant decrease in inpatient mortality and hospital LOS for patients with both IBD and anxiety compared to those with only IBD. Anxiety is known to be 2 to 3 times higher in patients with IBD, but it reduces morbidity and mortality. This may be due to the increased surveillance and treatment to this subgroup of patients. Given the known association between IBD and anxiety, clinicians be vigilant in detecting and treating concomitant anxiety as this could lead to better outcomes in this patient population, as our study revealed. Future randomized control trials are needed to further study the impact of anxiety on IBD.
