The presence of petechiae and red urine with elevated protein and red blood cells in the urinalysis are classic signs of Henoch-Schönlein purpura, which is a vascular disorder commonly seen in children following a respiratory infection. Minimal change disease is a leading cause of nephrotic syndrome in children but does not typically present with petechiae or red urine.
