ANSWER: Pankaj:

This time you're asking what are the possible causes; essentially a laundry list.  OK, but it won't help you much.

Renal pelvis tumor, prostatitis, inverted bladder papilloma, bladder tumor, hemorrhagic cystitis, bladder infection, renal or ureteral stones, bladder calculi, arterio-venous malformations, renal vein thrombosis, ureterocele, coagulopathy, Alport's syndrome, postl-streptococcal infection, glomerulonephritis, Goodpasture's syndrome, Henoch-Schonlein purpura, Systemic Lupus disease, sickle cell disease, tramua, etc., etc.

That's why we recommend seeing a pediatric urologist.

QUESTION: my ultrasound of abdomen was normal can there is still chanccer of tumor anywhere


Ultrasound is painless, cheap and has no radiation. It is also indistinct and not very reliable for lesions less tham 0.5 cm in size.  So the answer is yes; you could still have a tumor or a cancer that the ultrasound may have missed.  For example, tumors in the bladder are generally not visible on ultrasound.
