I am a 58 yr old female with history of kidney stones, hypertension. Went to my Doctor with visible blood in urine.  No infection. Had an ultrasound. It showed 2 kidney stones plus a small (.5cm) nonshadowing echogenic focus. They want to follow up with a CT scan and cystoscopy. It is not scheduled until 4 weeks from now.  Is this too long to wait if it is cancer?
Thanks for the query. As you had 2 kidney stones shown in USG, blood in urine means hematuria is due to this. Stones erode kidney and ureters wall which makes blood in urine. As nonshadowing echogenic shadow is most commonly due to hematoma or fibrosis. There are fewer chances of cancer. But to rule out ct scan is the best procedure. Get well soon...
