Ureteral cancer is cancer of the ureters, muscular tubes that propel urine from the kidneys to the urinary bladder. It is also known as ureter cancer,[1] renal pelvic cancer,[1] and rarely ureteric cancer or uretal cancer. Cancer in this location is rare.[1][2]
Ureteral cancer is usually transitional cell carcinoma.[2][3] Transitional cell carcinoma is "a common cause of ureter cancer and other urinary (renal pelvic) tract cancers."[1]
Between 1988 and 2001 in the United States, cancer surveillance reports to SEER included 1,333 cases of ureteral cancer in adults: 808 male and 525 female, 1,158 white and 42 black. Of the total, 1,251 (94%) were transitional cell carcinoma of the papillary type.[2] "Five-year relative survival rates from cancers of the ureter were similar among males vs. females..."[2]
Symptoms of ureteral cancer may include "blood in the urine (hematuria); diminished urine stream and straining to void (caused by urethral stricture); frequent urination and increased nighttime urination (nocturia); hardening of tissue in the perineum, labia, or penis; itching; incontinence; pain during or after sexual intercourse (dyspareunia); painful urination (dysuria); recurrent urinary tract infection; urethral discharge and swelling".[4]
Tobacco smoking is associated with an increased risk of ureteral cancer.[5]
Diagnosis may include a fluorescence in situ hybridization (FISH) test, computed tomography urography (CTU), magnetic resonance urography (MRU), intravenous pyelography (IVP) x-ray, ureteroscopy,[6] or biopsy.
Treatment methods include surgery,[1][7] chemotherapy,[1] radiation therapy[1] and medication.[1]
