I am having a 10 year boy with gross painless hematuria since 3 months. No s/o nephritis. No local lesion. Having retractile testes upto deep inguinal ring.
His USG abdomen shows multiple calysial calculi bilaterally, with chronic cystits. Interestingly he is not having gross hematuria in the morning. He starts getting hematuria in the afternoon. what shoud be suspected in this child?
