Rationale: Adult renal neuroblastoma (NB) is extremely rare, and there have been only a few cases previously described in the literature. We report a case of adult renal NB and summarize the clinical and imaging features of the reported cases.
Patient Concerns: A 41-year-old female was admitted to our hospital with a chief complaint of gross hematuria that had persisted for a month. Nonenhanced computed tomography (CT) revealed a hypodense right renal mass without calcification. Enhanced CT showed an infiltrative, heterogeneously enhancing right renal mass with retrocaval lymphadenopathy and right renal vein thrombus. Magnetic resonance imaging (MRI) revealed that the right renal mass was isointense relative to the renal parenchyma on nonenhanced T1-weighted images; it showed mixed hypointensity and hyperintensity on T2-weighted images, and heterogeneous enhancement with a hyperintense rim on fat-saturated, enhanced T1W images. The initial impression was renal cell carcinoma (RCC).
Diagnoses: Adult renal neuroblastoma.
Interventions: Right nephroureterectomy with lymph node dissection was performed. The pathology and immunohistochemistry confirmed the diagnosis of renal NB with retrocaval lymphadenopathy and retroperitoneal metastasis.
Outcomes: After surgery, the patient received 6 courses of chemotherapy, and no recurrence was observed during a 24-month follow-up period.
Lessons: The clinical picture of adult renal NB is that of a 44-year-old woman, presenting with an abdominal or renal mass about 13cm in size, accompanied by hypertension, hematuria, or pain. In contrast to CT features described in previous literature, no tumor calcification is mentioned in these adult renal NB cases. It is difficult to differentiate renal NB from RCC based on CT or MRI. However, biopsy, urinary catecholamine levels, and metaiodobenzylguanidine (MIBG) scan may aid in presurgical diagnosis.

With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is of increasing importance, where exposure to high altitude (HA) imposes a blood oxygenation and acid-base challenge. A sustained and augmented hypoxic ventilatory response protects oxygenation through ventilatory acclimatization, but elicits hypocapnia and respiratory alkalosis. A subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with a high degree of interindividual variability.

Introduction: Acute kidney injury (AKI) in the setting of COVID-19 is associated with worse clinical and renal outcomes, with limited long-term data.
Aim: To evaluate critically ill COVID-19 patients with AKI that required nephrologist consultation (NC-AKI) in a tertiary hospital.
Methods: Prospective single-center cohort of critically ill COVID-19 adult patients with NC-AKI from May 1st, 2020, to April 30th, 2021.

Collapsing glomerulopathy (CG) has a severe course typically associated with viral infections, especially HIV and parvovirus B19, systemic lupus erythematosus (SLE), among other etiologies. A 35-year-old woman with recent use of a JAK inhibitor due to rheumatoid arthritis presented with a 2-week history of fever, cervical adenopathy, and facial erythema. After admission, anemia, hypoalbuminemia, proteinuria, and severe acute kidney injury were noted.

Introduction: Unplanned initiation of renal replacement therapy (RRT) in chronic kidney disease (CKD) patients is a common situation worldwide. In this scenario, peritoneal dialysis (PD) has emerged as a therapeutic option compared to hemodialysis (HD). In planned RRT, the costs of PD are lower than those of HD; however, the literature lacks such analyses when initiation is urgent.

Rationale: Thrombotic microangiopathies (TMA) caused by malignant hypertension is an acute and critical disease among rare diseases. Although renal biopsy pathology is a golden indicator for diagnosing kidney disease, it cannot distinguish between primary and secondary TMA and requires a comprehensive diagnosis in conjunction with other laboratory tests and medical history.
Patient Concerns: A 33-year-old young man was hospitalized due to unexplained kidney failure.
