What is a ureteral tumor?

A ureteral tumor is a type of cancer that develops in the ureter, the thin tube that connects the kidney to the bladder. This type of tumor is relatively rare and is most commonly urothelial carcinoma, which begins in the cells lining the inside of the ureter. The tumor can block the flow of urine, leading to pain, infection, or even kidney damage.


The diagnosis of ureteral tumors usually involves a series of tests and procedures. Common approaches include urinary cytology—testing a urine sample for the presence of abnormal cells—and imaging techniques like ultrasound, CT scans, or MRI, which help visualize the ureter and identify abnormal changes. Ureteroscopy may also be required, where a doctor uses a thin, flexible tube with a camera to look directly inside the ureter and kidney. During ureteroscopy, a biopsy can be performed to confirm the nature of the tumor.


Laparoscopic nephroureterectomy is the standard surgical treatment for ureteral tumors. This procedure involves removing the entire kidney along with the ureter and a part of the bladder into which the ureter drains. Laparoscopy allows surgeons to perform the operation through several small incisions instead of one large one, which leads to less pain after surgery and a faster recovery.
Benefits of the laparoscopic method include a lower risk of infection, less blood loss during surgery, and a shorter hospital stay.
Postoperative recovery typically involves monitoring the function of the remaining kidney and regular check-ups to ensure there is no recurrence of cancer.
The choice of treatment depends on the stage and type of the tumor, as well as the patient’s overall health condition. In some cases, if the tumor is localized and has not spread, less invasive options like endoscopic tumor removal may be considered. However, complete nephroureterectomy remains the gold standard for most ureteral tumors.
