What is urothelial cancer?
Bladder and other urothelial cancers are diseases in which malignant (cancer) cells form in the urothelium. The bladder is a hollow organ in the lower part of the abdomen. It is shaped like a small balloon and has a muscle wall that allows it to get larger or smaller to store urine made by the kidneys.
What is the urothelium in the urinary tract?

The prognosis of the Urothelial Carcinoma depends upon the invasive nature of the malignancy and spreading of metastasizing. In the case of initial stage low-grade cancerous lesion provides a good prognosis, whereas poor prognosis is reported with the high grade cancerous lesion. The local invasion of the carcinoma can provide 5 years survival, whereas involvement of the lymph nodes can cause 0 to 30 percent 5 years survival 1.

What is the name of the cancer that occurs in the bladder?
Upper Tract Urothelial Cancer. Urothelial cancer refers to a cancer of the lining of the urinary system. While the majority of urothelial cancers (approximately 90-95%) arise in the bladder, upper tract urothelial cancers (UTUCs) correspond to a subset of urothelial cancers that arise in the lining of the kidney (called the renal pelvis) ...
Can a UTUC spread to the kidney?
Similar to bladder cancers, UTUCs can develop as low- or high-grade tumors. In general, low-grade tumors are not invasive and very rarely spread from the kidney or ureter. However, they often recur and management involves treating visible tumors and trying to preserve the urinary tract – as these tumors are more likely to recur in the urinary system than they are to spread. High-grade tumors have an aggressive appearance under a microscope and are assumed invasive in the kidney or ureter. In the bladder, a thick bladder muscle (called the detrusor) acts as a barrier to confine invasive cancers but in the kidney and ureter, this muscle does not exist. High-grade UTUC has the potential to spread from the kidney or ureter and is most often treated with surgical removal of the kidney and ureter – an operation called radical nephrouretectomy. High-grade UTUC can be aggressive and an expert may recommend systemic therapy (for example, chemotherapy) before or after surgery to reduce the risk of recurrence elsewhere in the body. An expert pathologist is often enlisted to determine low- and high-grade urothelial cancers, as this distinction can dramatically impact management choices.
What is the ratio of urothelial cancer?
Urothelial cancers encompass carcinomas of the bladder, ureters, and renal pelvis, which occur at a ratio of 50:3:1, respectively. Cancer of the urothelium is a multifocal process.

Symptoms
Causes
- There is no single factor that causes bladder cancer to develop. Urothelial bladder cancer develops when the genetic material (DNA) inside of the urothelial cells lining the bladder becomes abnormal. These abnormal cells then divide and produce more abnormal cells. As more abnormal cells are made, the tumor develops. Though there is not one specifi...
Diagnosis
- When a bladder cancer diagnosis is suspected, many tests can be performed to help determine the cause of the symptoms and make the diagnosis.
Treatment
- Treatment for urothelial bladder cancer is dependent upon the stage of the cancer. Multiple treatments may be given in combination to best treat the cancer.
Prognosis
- The prognosis of urothelial bladder cancer varies based on how advanced the cancer has grown, as well as the size of the tumor, and if it is a new tumor or has regrown. The five-year survival rate—the percentage of people still alive at five years after diagnosis—for bladder cancer that has not gone into deeper layers is 96%. If a tumor has invaded deeper layers but not the muscle wall…
Coping
- A bladder cancer diagnosis may cause stress and worry. Side effects from the cancer or the treatments may cause distressing changes to the body. Finding ways to cope with these changes—through support groups or with family and friends—may be helpful. Discussing expectations and concerns with your healthcare team may be helpful as well.
A Word from Verywell
- If you’re experiencing symptoms, especially blood in the urine, or if you are concerned that you may have bladder cancer, don’t hesitate to reach out to your healthcare team to discuss your concerns. It is very possible that the symptoms you’re having may be due to other reasons, such as a urinary tract infection. But if caught early, bladder cancer has a much better prognosis, so it'…
