A 7-year-old boy presents following the passage of red-colored urine one day ago. This was limited to a single episode and resolved spontaneously. He had experienced a mild fever and sore throat for the preceding four days, but these symptoms have resolved now.
There is no history of dysuria or urinary frequency. His medical history is unremarkable, and he is not on any drugs currently. His growth and development are age appropriate, and all immunizations are up to date.
His family history is significant for chronic kidney disease in a maternal uncle at the age of 25 years. However, the underlying cause is unknown, and medical documentation in this respect is unavailable.
Urinalysis reveals microhematuria, microalbuminuria, erythrocyte casts, and dysmorphic cells. A complete blood count, liver profile, renal profile, and serum electrolyte assay are all within normal parameters.
