Ureteral Tumors

Ureteral tumours are abnormal growths that start in the ureters, which are the tubes that connect the kidneys to the bladder. They are mostly urothelial carcinomas, which account for more than 90% of cases. Other types, like squamous cell carcinoma, are less prevalent. Ureteral tumours are uncommon relative to bladder or renal pelvis tumours and typically manifest more frequently in older individuals, particularly males over 50. Symptoms often include haematuria (blood in the urine), flank pain, frequent urination, and sometimes weight loss or weariness. These tumours can stop urine from flowing, which can lead to hydronephrosis, which is enlargement of the kidney. Imaging tests like CT urography or intravenous pyelography are often used to make a diagnosis.

It can be as simple as removing the affected ureter segments or as complex as removing parts of the kidney or bladder connected to the tumour.

Chemotherapy or radiotherapy may be needed for advanced tumours. Risk factors include smoking, exposure to chemicals, abusing painkillers, and having a family history of the disease. Ureteral tumours can spread to other organs through the lymphatic or blood systems. Early identification is essential because some ureteral tumours are aggressive and can spread. The prognosis differs according to the stage of cancer and the efficacy of treatment.
