RESUMO
Pathological renal mass is uncommon in children. It is important to differentiate this from a benign mass or mass-like lesion (pseudomass) for proper management. Renal dysplasia is a common finding in patients with end stage renal disease and can mimic a renal mass. Here, we report a 16-year-old girl on hemodialysis who was found to have a nodular right renal mass in the sonogram. Magnetic resonance imaging confirmed the nodular mass. She underwent right nephrectomy and the histopathology revealed features of renal dysplasia and end stage kidney disease without any evidence of malignancy. No further treatments were necessary. This case demonstrates that a nodular renal mass in dialysis patients does not always mean malignancy and could be a pseudomass from severe renal dysplasia. Since a sonogram may not be able to clearly define the etiology of solid mass in these patients, further evaluations including a renal histology and/or other imaging modalities are often necessary.

INTRODUCTION: Outpatient stress testing (OST) after evaluation in the emergency department (ED) is an acceptable evaluation method for patients presenting to the ED with low-risk chest pain (CP). However, not all patients return for OST. Barriers to follow-up evaluation exist and are poorly understood. In this study, we examined the influence of demographic and social characteristics on OST compliance. METHODS: Data were collected on low-risk CP patients with scheduled OSTs. OST compliance was assessed and then analyzed for correlation with potential barriers including insurance type; age; sex; race; employment status; the distance the patient lived from the hospital; whether or not the patient had a primary care physician; whether or not the patient had a history of hypertension or diabetes; and whether or not the patient had a history of tobacco, alcohol, or illicit drug use. RESULTS: A total of 275 patients were enrolled over a 5-month period. These patients had an OST follow-up rate of 61.82% within 72hours of discharge from the ED. Patients with Medicaid were statistically less likely (odds ratio [OR], 0.439) to complete OST. Patients with commercial insurance (OR, 1.8225), who were employed (OR, 2.299), or who were retired (OR, 3.44) were more likely to complete OST. All of the other variables analyzed were not statistically significant factors in OST compliance. CONCLUSION: More than one-third of low-risk CP patients do not follow-up with scheduled OST. Of the variables analyzed, both employment status and insurance type were statistically significant and should be included in risk stratification strategies for OST.
