Preclinical gout is common in the patient with stage 3-5 chronic kidney disease. Relevance of musculoskeletal ultrasound.

Background: One in 10 patients with hyperuricemia may develop gout over time, with urate deposition sometimes asymptomatic. Recent reviews and guidelines support ultrasound (US) to assess asymptomatic hyperuricemic (AH) patients to detect gout lesions, showing double contour (DC) and tophus the highest specificities and positive predictive values. Hyperuricemia and gout are common in chronic kidney disease (CKD), especially with glomerular filtration rate (GFR) <60, and both are associated with worse prognosis, although treatment of AH in CKD is not yet recommended in all guidelines.
