Harvey has been having small amounts of blood in his urine and intense waves of pain in his back and abdomen. What urinary disease or disorder do these symptoms suggest?

Blood in the urine together with intense, wave-like pain in the back and abdomen strongly suggests kidney stones. A stone moving through the urinary tract can cause severe waves of pain and may irritate tissue, leading to blood in the urine. Interstitial cystitis, incontinence, and a typical urinary tract infection do not match this pattern as well.
