Hello I have a 2 year who was diagnosed with bilateral hydronephrosis at 3 months old due to hypertension and it has since resolved but now has grade 1 pelviectasis and a few lesions on his right kidney that measure between 2-3 mm each and are in his upper pole as well as polyuria and hypertension still and tachycardia I feel like the doctors aren t doing anything or looking into this enough he also has some other medical issues that are being blown off but what should I do ?
