The presence of red blood cell casts in urine indicates a relatively high concentration of red blood cells in the urine. This suggests possible infection or hemorrhagic disease within the urinary system, such as kidney stones or ureteral stones. In some cases, malignancies—including bladder cancer or renal cell carcinoma—should also be considered; however, further diagnostic evaluation would be required to confirm such conditions. Only after thorough investigation and definitive diagnosis can appropriate, targeted treatment be initiated.
