Been having microscopic blood in urine for a month. if cystoscopy and ultrasound of kidneys are both normal do i accept its idiopathic or if not what would be the next steps to figure it out?

Hematuria: Microscopic hematuria indicates a renal source. Given the normal renal ultrasound a mass unlikely. Microscopic hematuria can be from benign causes like exercise. Could this be some type of sign of glomerular problem, but if so management would be modifying risk factors like BP, blood sugar and weight. Talk to your doctor or nephrologist for guidance on best follow-up.
