Transitional cell carcinoma of the kidney

Transitional cell carcinoma of the kidney occurs in the renal pelvis. The renal pelvis is the center of the kidney where urine collects before travelling down the ureters to the bladder. The tissue that lines this area has cells called transitional cells. They are able to bend and stretch without being damaged. Transitional cell carcinoma forms in these cells.Transitional cell carcinoma can be either high grade or low grade. Low grade is less likely to spread to other areas or have a recurrence. High grade is more likely to metastasize to other parts of the body, like lymph nodes, and has a higher chance of returning after treatment. The grading is assessed by a biopsy.Transitional cell carcinoma can affect both males and females but most commonly affects males between the ages of 60-70 years old.
