Ureteral cancer is most often due to cancer of the cells lining the ureter, called transitional cell carcinoma, although it can more rarely occur as a squamous cell carcinoma if the type of cells lining the urethra have changed due to chronic inflammation, such as due to stones or schistosomiasis.

Ureteritis is a medical condition of the ureter that involves inflammation. [1] [2] One form is known as "ureteritis cystica". [3] Eosinophilic ureteritis has been observed. [4] Ureteritis is often considered part of a urinary tract infection. [citation needed]
Facet cells (also known as umbrella cells, [1] capping cells, superficial urotheliocytes) are a type of cells located in the renal pelvis, the ureters, and the urethra. Umbrella cells form the outermost layer of the urothelium, which is a special type of epithelium found in the renal pelvis, the ureters, and the urethra.

Kidney stones are becoming more common with time, and their incidence is believed to increase recently due to unhealthy diet habits. The passage of kidney stones into ureters might lead to their impaction and the development of local inflammatory process around the stone in addition to the obstruction of the ipsilateral kidney and build up of pressure manifested as hydronephrosis.
Organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymides, vasa deferentia, seminal vesicles, prostate, and penis). The urinary and reproductive tracts are closely linked, and disorders of one often affect the other.
Thereafter, terms "ureter" and "urethra" were variably used to refer to each other thereafter for more than a millennia. [31] It was only in the 1550s that anatomists such as Bartolomeo Eustacchio and Jacques Dubois began to use the terms to specifically and consistently refer to what is in modern English called the ureter and the urethra.
