Complications after interventional treatment for renal cancer
Post-intervention complications of renal cancer can include hematuria, lower back pain, and tumor recurrence. Hematuria is indirect and painless, visible to the naked eye. Renal cancer often accompanies renal colic, which is due to the formation of ureteral blood clots. Blood clots from renal cell carcinoma can form a ribbon-like shape through the ureter, and the degree of hematuria is not related to the size of the renal cell carcinoma. Renal cell carcinoma sometimes presents persistent microscopic hematuria. Lower back pain is a common symptom, often an intermittent dull pain, usually due to the enlargement of the kidney tumor. When the tumor invades surrounding organs and the psoas major muscle, the pain is heavy and persistent.
