Hematuria, or blood in the urine, can be one of the primary symptoms of renal tumors. As these tumors grow, they can lead to bleeding within the kidney or the urinary tract, which is often reflected in the presence of blood upon urination.

Renal cancer can present with other symptoms, but it often gives rise to isolated hematuria, particularly in its early stages. This distinguishing feature makes renal cancer particularly suspect when hematuria occurs without accompanying signs of urinary tract infection, such as dysuria, frequency, or urgency.

Acute glomerulonephritis, for example, is often accompanied by proteinuria and symptoms such as edema and hypertension. Ureteral stones usually lead to severe pain and may also involve other signs. Renal vein thrombosis can be associated with flank pain and swelling or signs of underlying nephropathy.
